Efficacy of the feed additive consisting of Saccharomyces cerevisiaeCNCM I-4407 (Actisaf® Sc47) for cattle for fattening (Lesaffre International).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of Saccharomyces cerevisiae CNCM I-4407 (Actisaf® Sc47) as a zootechnical feed additive (functional group: gut flora stabiliser) in cattle for fattening. The additive is already authorised for use in feed for dairy cows, calves for rearing, lambs for fattening, dairy goats, dairy sheep and dairy buffaloes. In a previous opinion, the EFSA Scientific Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) concluded that Actisaf® Sc47 was safe for cattle for fattening, the consumers and the environment. Additionally, the Panel considered that Actisaf® Sc47 is not a skin irritant, and no conclusions could be drawn on the additive's eye irritancy and dermal sensitisation potential. Due to the lack of adequate data, the Panel could not conclude on the efficacy of the additive in cattle for fattening at the proposed conditions of use. In the current application, the applicant submitted three trials to support the efficacy in cattle for fattening. However, two of them were not considered for the assessment. The other trial showed an improved zootechnical performance of the animals at the proposed use level of 4 × 109 CFU/kg complete feed. Considering the additive is authorised in dairy cows and calves for rearing and the requirements of the current Guidance on the assessment of the efficacy of feed additives, no further demonstration of efficacy is necessary to extrapolate the conclusions previously reached to all ruminants. The significant positive effect shown in one trial in cattle for fattening supports the above extrapolation. Therefore, the FEEDAP Panel concludes that Actisaf® Sc47 is efficacious as a zootechnical additive for cattle for fattening at the proposed conditions of use.

Acrylamide increases and furanoic compounds decrease in plant-based meat alternatives during pan-frying

Plant-based meat alternatives are gaining popularity as protein sources. However, pan-frying may lead to the formation of potentially harmful food contaminants. We investigated the formation of acrylamide and furanoic compounds in four different plant-based meat alternatives and two meat burger patties during pan-frying at 160 and 200 °C. The highest acrylamide contents (72. ± 7.7 and 69.2 ± 9.5 µg/kg, respectively) were found in soy flour- and sunflower-protein based patties fried at 200 °C. Unprepared pea and soy protein-based burger patties contained the highest furfural amounts (2832.8 ± 576.2 and 2683.0 ± 868.5 µg/kg, respectively). Furfuryl alcohol content was highest in soy flour-based patties and increased temperature-dependently up to 1120.9 ± 383.4 µg/kg. Based on the tolerable intake calculated by the EFSA Scientific Panel on Contaminants in the Food Chain, these amounts do not pose a health risk. Nevertheless, since plant-based novel food are being increasingly consumed, further investigations into the formation of food contaminants in novel processed foods are warranted.

Update of the list of qualified presumption of safety (QPS) recommended microorganisms intentionally added to food or feed as notified to EFSA

The qualified presumption of safety (QPS) provides a generic pre-assessment of the safety of microorganisms intended for use in the food or feed chains, to support the work of EFSA's Scientific Panels. QPS assessment allows a fast track evaluation of strains belonging to QPS taxonomic units (TUs): species for bacteria, yeast, fungi, protists/microalgae and families for viruses. QPS TUs are assessed for their body of knowledge and safety. Safety concerns related to a QPS TU are reflected, when possible, as ‘qualifications’, which should be tested at strain and/or product level. Based on the possession of potentially harmful traits by some strains, filamentous fungi, bacteriophages, oomycetes, streptomycetes, Enterococcus faecium, Escherichia coli and Clostridium butyricum are excluded from the QPS assessment. Between October 2019 and September 2022, 323 notifications of TUs were received, 217 related to feed additives, 54 to food enzymes, food additives and flavourings, 14 to plant protection products and 38 to novel foods. The list of QPS-recommended TUs is reviewed every 6 months following an extensive literature search strategy. Only sporadic infections with a few QPS status TUs in immunosuppressed individuals were identified and the assessment did not change the QPS status of these TUs. The QPS list has been updated in relation to the most recent taxonomic insights and the qualifications were revised and streamlined. The qualification ‘absence of aminoglycoside production ability’ was withdrawn for Bacillus velezensis. Six new TUs received the QPS status: Bacillus paralicheniformis with the qualification ‘absence of toxigenic activity’ and ‘absence of bacitracin production ability’; Bacillus circulans with the qualifications for ‘production purposes only’ and ‘absence of cytotoxic activity’; Haematococcus lacustris (synonym Haematococcus pluvialis) and Ogataea polymorpha, both with the qualification ‘for production purposes only’; Lactiplantibacillus argentoratensis; Geobacillus thermodenitrificans with the qualification ‘absence of toxigenic activity’.

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 17: suitability of taxonomic units notified to EFSA until September 2022.

The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre-evaluation of the safety of microorganisms, intended for use in the food or feed chains, to support the work of EFSA's Scientific Panels. The QPS approach is based on an assessment of published data for each agent, with respect to its taxonomic identity, the body of relevant knowledge and safety concerns. Safety concerns identified for a taxonomic unit (TU) are, where possible, confirmed at the species/strain or product level and reflected by 'qualifications'. In the period covered by this Statement, new information was found leading to the withdrawal of the qualification 'absence of aminoglycoside production ability' for Bacillus velezensis. The qualification for Bacillus paralicheniformis was changed to 'absence of bacitracin production ability'. For the other TUs, no new information was found that would change the status of previously recommended QPS TUs. Of 52 microorganisms notified to EFSA between April and September 2022 (inclusive), 48 were not evaluated because: 7 were filamentous fungi, 3 were Enterococcus faecium, 2 were Escherichia coli, 1 was Streptomyces spp., and 35 were taxonomic units (TUs) that already have a QPS status. The other four TUs notified within this period, and one notified previously as a different species, which was recently reclassified, were evaluated for the first time for a possible QPS status: Xanthobacter spp. could not be assessed because it was not identified to the species level; Geobacillus thermodenitrificans is recommended for QPS status with the qualification 'absence of toxigenic activity'. Streptoccus oralis is not recommended for QPS status. Ogataea polymorpha is proposed for QPS status with the qualification 'for production purposes only'. Lactiplantibacillus argentoratensis (new species) is included in the QPS list.

Maintenance, update and further development of EFSA's Chemical Hazards: OpenFoodTox 2.0

This report provides a summary of the activities undertaken in the third year of the framework contract (OC/EFSA/SCER/2018/01) to maintain, update and further develop the OpenFoodTox database (“OpenFodTox 2.0”) (OFT 2.0). OFT has been developed to map hazards data from EFSA documents (opinions, statements, and conclusions) on risk assessment of chemicals in food and feed. It holds summary data on identification of chemicals, document descriptors, hazard identification and hazard characterisation. Within OFT 2.0, hazard data collection and entry assessed by EFSA scientific panels was performed according to the existing data model and data for 92 new substances and 139 new hazard assessments from 61 EFSA documents were added. OpenFoodTox 2.0 now includes more than 10500 assessments for over 5200 chemicals from 2250 documents. In addition, the data collection process of new data has been continued, extended and synchronised with further expansion of the data model for physicochemical properties (OHT 1 to 23-5), toxicokinetic (TK) and metabolism data (OHT 58). Overall, new data include 3719 physicochemical datasets (139 substances, 131 EFSA outputs), 2008 PK/TK datasets (252 substances, 252 documents), metabolism data (115 studies, 39 parent substances, 121 related metabolites, 31 EFSA documents). A case study to integrate results from different OHTs for implementing the use of overarching guidance documents is proposed as a Flexible summary, together with an application using a data poor scenario. An update on the conazoles case study is reported with, an analysis of in vitro and in vivo data from OFT and an analysis of aromatase and steroidogenesis interference. Furhtermore, results on new QSAR models are presented as part of the design of an in silico integrative tool allowing description and prediction of chemical hazard properties. Finally, a means to link VEGA Hub, containing a large number of QSAR models and read-across tools, and OFT 2.0 is proposed.

Update of the list of QPS-recommended microbiological agents intentionally added to food or feed as notified to EFSA 16: suitability of taxonomic units notified to EFSA until March 2022.

The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre‐evaluation of the safety of microorganisms, intended for use in the food or feed chains, to support the work of EFSA's Scientific Panels. The QPS approach is based on an assessment of published data for each agent, with respect to its taxonomic identity, the body of relevant knowledge, safety concerns and occurrence of antimicrobial resistance. Safety concerns identified for a taxonomic unit (TU) are, where possible, confirmed at the species/strain or product level and reflected by ‘qualifications’. In the period covered by this statement, no new information was found that would change the status of previously recommended QPS TUs. Of the 50 microorganisms notified to EFSA in October 2021 to March 2022 (inclusive), 41 were not evaluated: 10 filamentous fungi, 1 Enterococcus faecium, 1 Clostridium butyricum, 3 Escherichia coli and 1 Streptomyces spp. because are excluded from QPS evaluation, and 25 TUs that have already a QPS status. Nine notifications, corresponding to seven TUs were evaluated: four of these, Streptococcus salivarius, Companilactobacillus formosensis, Pseudonocardia autotrophica and Papiliotrema terrestris, being evaluated for the first time. The other three, Microbacterium foliorum, Pseudomonas fluorescens and Ensifer adhaerens were re‐assessed. None of these TUs were recommended for QPS status: Ensifer adhaerens, Microbacterium foliorum, Companilactobacillus formosensis and Papiliotrema terrestris due to a limited body of knowledge, Streptococcus salivarius due to its ability to cause bacteraemia and systemic infection that results in a variety of morbidities, Pseudonocardia autotrophica due to lack of body of knowledge and uncertainty on the safety of biologically active compounds which can be produced, and Pseudomonas fluorescens due to possible safety concerns.

Update of the list of QPS‐recommended biological agents intentionally added to food or feed as notified to EFSA 14: suitability of taxonomic units notified to EFSA until March 2021

The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre‐evaluation of the safety of biological agents, intended for addition to food or feed, to support the work of EFSA's Scientific Panels. The QPS approach is based on an assessment of published data for each agent, with respect to its taxonomic identity, the body of relevant knowledge, safety concerns and occurrence of antimicrobial resistance. Safety concerns identified for a taxonomic unit (TU) are, where possible, confirmed at the species/strain or product level and reflected by ‘qualifications’. In the period covered by this statement, no new information was found that would change the status of previously recommended QPS TUs. Schizochytrium limacinum, which is a synonym for Aurantiochytrium limacinum, was added to the QPS list. Of the 78 microorganisms notified to EFSA between October 2020 and March 2021, 71 were excluded; 16 filamentous fungi, 1 Dyella spp., 1 Enterococcus faecium, 7 Escherichia coli, 1 Streptomyces spp., 1 Schizochytrium spp. and 44 TUs that had been previously evaluated. Seven TUs were evaluated: Corynebacterium stationis and Kodamaea ohmeri were re‐assessed because an update was requested for the current mandate. Anoxybacillus caldiproteolyticus, Bacillus paralicheniformis, Enterobacter hormaechei, Eremothecium ashbyi and Lactococcus garvieae were assessed for the first time. The following TUs were not recommended for QPS status: A. caldiproteolyticus due to the lack of a body of knowledge in relation to its use in the food or feed chain, E. hormaechei, L. garvieae and K. ohmeri due to their pathogenic potential, E. ashbyi and C. stationis due to a lack of body of knowledge on their occurrence in the food and feed chain and to their pathogenic potential. B. paralicheniformis was recommended for the QPS status with the qualification ‘absence of toxigenic activity’ and ‘absence of genetic information to synthesize bacitracin’.

Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 13: suitability of taxonomic units notified to EFSA until September 2020.

The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre‐evaluation of the safety of biological agents, intended for addition to food or feed, to support the work of EFSA's Scientific Panels. It is based on an assessment of published data for each agent, with respect to its taxonomic identity, the body of knowledge, safety concerns and antimicrobial resistance. Safety concerns identified for a taxonomic unit (TU) are, where possible, confirmed at strain or product level, and reflected by ‘qualifications’. In the period covered by this statement, no new information was found that would change the status of previously recommended QPS TUs. Of the 36 microorganisms notified to EFSA between April and September 2020, 33 were excluded; seven filamentous fungi (including Aureobasidium pullulans based on recent taxonomic insights), one Clostridium butyricum, one Enterococcus faecium, three Escherichia coli, one Streptomyces spp. and 20 TUs that had been previously evaluated. Three TUs were evaluated; Methylorubrum extorquens and Mycobacterium aurum for the first time and Bacillus circulans was re‐assessed because an update was requested in relation to a new mandate. M. extorquens and M. aurum are not recommended for QPS status due to the lack of a body of knowledge in relation to use in the food or feed chain and M. aurum, due to uncertainty concerning its pathogenicity potential. B. circulans was recommended for QPS status with the qualifications for ‘production purposes only’ and ‘absence of cytotoxic activity’.

Physiologically based pharmacokinetic (PBPK) modeling reliability in human exposure assessment after a perfluoroalkyl substances (PFAS) contamination occurred in northern Italy.

Background and goals: A wide area in the Veneto region (northern Italy) has been faced a perfluoroalkyl substances (PFAS) contamination occurred mainly in groundwater and drinking water. Exposure of the population likely started in the Sixties, had a sure decrease after filters installation in 2013. The Veneto Region is conducting a biomonitoring study to investigate health conditions of the exposed population, collecting hundreds of serum samples. Some Physiologically based Pharmacokinetic (PBPK) models are being tested comparing PFOA and PFOS measured levels with the estimated ones.Methods: Original Loccisano model corrected by EFSA Scientific Panel was tested for this case study. A worst case scenario (WCS) and a best case scenario (BCS) were developed. Both scenarios took into account individual simulations carried out on 25 people (11 men and 14 women), aged 22-39 years, living in an area with both groundwater and drinking water contamination. WCS considered water intake from the private well, company water and bottled water in the same proportion. In the BCS we assumed 1/3 of the water intake from drinking water and 2/3 from bottled water.Results: Estimated average PFOA serum level obtained from the WCS was very near to the measured one for men (E:151.4±68.4;M:108.6±51.0 ng/mL), while was farther but still quite near the measured value for women (E:132.2±108.2;M:30.9±30.1 ng/mL). In the BCS the result is the opposite (men, E:23.9±10.4; women, E:22.1±13.2 ng/mL).Conclusions: Model seems to predict well PFOA serum levels in the exposed population even with high entity of uncertainties. Loccisano model is a multi-compartment PBPK model created specifically for PFAS, but with no modelization of menstruation and pregnancy losses. New simulations are being running to increase statistical significance but we are also looking at other models to take into account gender differences, to explain differences between men and women observed in measured data.

Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 12: suitability of taxonomic units notified to EFSA until March 2020.

The qualified presumption of safety (QPS) was developed to provide a generic safety evaluation for biological agents to support EFSA's Scientific Panels. It is based on an assessment of the taxonomic identity, the body of knowledge, safety concerns and antimicrobial resistance. Safety concerns identified for a taxonomic unit (TU) are where possible to be confirmed at strain or product level, reflected by ‘qualifications’. No new information was found that would change the previously recommended QPS TUs of the 39 microorganisms notified to EFSA between October 2019 and March 2020, 33 were excluded, including five filamentous fungi, five Escherichia coli, two Enterococcus faecium, two Streptomyces spp. and 19 TUs already evaluated. Six TUs were evaluated. Akkermansia muciniphila was not recommended for QPS status due to safety concerns. Clostridium butyricum was not recommended because some strains contain pathogenicity factors. This TU was excluded for further QPS evaluation. Galdieria sulphuraria and Pseudomonas chlororaphis were also rejected due to a lack of body of knowledge. The QPS status of Corynebacterium ammoniagenes (with the qualification ‘for production purposes only’) and of Komagataella pastoris (with the qualification ‘for enzyme production’) was confirmed. In relation to the taxonomic revision of the Lactobacillus genus, previously designated Lactobacillus species will be reassigned to the new species and both the old and new names will be retained in the QPS list.

Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 11: suitability of taxonomic units notified to EFSA until September 2019.

Qualified presumption of safety (QPS) was developed to provide a generic safety evaluation for biological agents to support EFSA's Scientific Panels. The taxonomic identity, body of knowledge, safety concerns and antimicrobial resistance are assessed. Safety concerns identified for a taxonomic unit (TU) are where possible to be confirmed at strain or product level, reflected by ‘qualifications’. No new information was found that would change the previously recommended QPS TUs and their qualifications. The list of microorganisms notified to EFSA was updated with 54 biological agents, received between April and September 2019; 23 already had QPS status, 14 were excluded from the QPS exercise (7 filamentous fungi, 6 Escherichia coli, Sphingomonas paucimobilis which was already evaluated). Seventeen, corresponding to 16 TUs, were evaluated for possible QPS status, fourteen of these for the first time, and Protaminobacter rubrum, evaluated previously, was excluded because it is not a valid species. Eight TUs are recommended for QPS status. Lactobacillus parafarraginis and Zygosaccharomyces rouxii are recommended to be included in the QPS list. Parageobacillus thermoglucosidasius and Paenibacillus illinoisensis can be recommended for the QPS list with the qualification ‘for production purposes only’ and absence of toxigenic potential. Bacillus velezensis can be recommended for the QPS list with the qualification ‘absence of toxigenic potential and the absence of aminoglycoside production ability’. Cupriavidus necator, Aurantiochytrium limacinum and Tetraselmis chuii can be recommended for the QPS list with the qualification ‘production purposes only’. Pantoea ananatis is not recommended for the QPS list due to lack of body of knowledge in relation to its pathogenicity potential for plants. Corynebacterium stationis, Hamamotoa singularis, Rhodococcus aetherivorans and Rhodococcus ruber cannot be recommended for the QPS list due to lack of body of knowledge. Kodamaea ohmeri cannot be recommended for the QPS list due to safety concerns.

Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 10: Suitability of taxonomic units notified to EFSA until March 2019.

The qualified presumption of safety (QPS) procedure was developed to provide a harmonised generic pre‐evaluation to support safety risk assessments of biological agents performed by EFSA's Scientific Panels. The taxonomic identity, body of knowledge, safety concerns and antimicrobial resistance were assessed. Safety concerns identified for a taxonomic unit (TU) are, where possible and reasonable in number, reflected by ‘qualifications’ which should be assessed at the strain level by the EFSA's Scientific Panels. During the current assessment, no new information was found that would change the previously recommended QPS TUs and their qualifications. The list of microorganisms notified to EFSA from applications for market authorisation was updated with 47 biological agents, received between October 2018 and March 2019. Of these, 19 already had QPS status, 20 were excluded from the QPS exercise by the previous QPS mandate (11 filamentous fungi) or from further evaluations within the current mandate (9 notifications of Escherichia coli). Sphingomonas elodea, Gluconobacter frateurii, Corynebacterium ammoniagenes, Corynebacterium casei, Burkholderia ubonensis, Phaeodactylum tricornutum, Microbacterium foliorum and Euglena gracilis were evaluated for the first time. Sphingomonas elodea cannot be assessed for a possible QPS recommendation because it is not a valid species. Corynebacterium ammoniagenes and Euglena gracilis can be recommended for the QPS list with the qualification ‘for production purposes only’. The following TUs cannot be recommended for the QPS list: Burkholderia ubonensis, due to its potential and confirmed ability to generate biologically active compounds and limited of body of knowledge; Corynebacterium casei, Gluconobacter frateurii and Microbacterium foliorum, due to lack of body of knowledge; Phaeodactylum tricornutum, based on the lack of a safe history of use in the food chain and limited knowledge on its potential production of bioactive compounds with possible toxic effects.

Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 9: suitability of taxonomic units notified to EFSA until September 2018.

The qualified presumption of safety (QPS) procedure was developed to provide a harmonised generic pre‐evaluation to support safety risk assessments of biological agents performed by EFSA's Scientific Panels. The taxonomic identity, body of knowledge, safety concerns and antimicrobial resistance were assessed. Safety concerns identified for a taxonomic unit are, where possible and reasonable in number, reflected by ‘qualifications’ which should be assessed at the strain level by the EFSA's Scientific Panels. During the current assessment, no new information was found that would change the previously recommended QPS taxonomic units and their qualifications. Between April and September 2018, the QPS notification list was updated with 48 microorganisms from applications for market authorisation. Of these, 30 biological agents already had QPS status, 15 were excluded from the QPS exercise by the previous QPS mandate (five filamentous fungi) or from further evaluations within the current mandate (two notifications of Enterococcus faecium, one of Streptomyces spp. and seven of Escherichia coli). One taxonomic unit was (re)evaluated: Pseudomonas fluorescens had been previously evaluated in 2016, and was now re‐evaluated within this mandate. The revision of the literature supports the previously identified safety concerns (e.g. production of biocompounds with antimicrobial activity and virulence features), preventing the inclusion of P. fluorescens in the QPS list. Mycobacterium setense and Komagataeibacter sucrofermentans were evaluated for the first time. M. setense cannot be considered for the QPS assessment because there are significant safety concerns. K. sucrofermentans (Acetobacter xylinus subsp. sucrofermentans) can be proposed for the QPS list but only for production purposes. The QPS status of Corynebacterium glutamicum is confirmed with the qualification extended to other production purposes.

Outcome of the public consultation on the draft Guidance of the EFSA PLH Panel on quantitative pest risk assessment

EFSA has carried out a public consultation on the draft Guidance of the EFSA Scientific Panel on Plant Health (PLH Panel) on quantitative pest risk assessment with the aim of collecting input from the scientific community and all interested parties. The draft Guidance was prepared by the dedicated Working Group of the PLH Panel. It provides guidance on the methodology to conduct quantitative pest risk assessment and the evaluation of risk reduction options. The methodology consists of a two-phase approach. Phase one consists of pest categorisation to determine whether the pest has the characteristics of a quarantine pest or those of a regulated non-quarantine pest for the area of the EU. Phase two consists of pest risk assessment and is a more detailed assessment to inform phytosanitary decision making. Following the endorsement of the draft Guidance by the PLH Panel, the public consultation was launched on 12 February 2018 and closed on 25 March 2018. EFSA received 178 comments on the draft Guidance from 11 interested parties. This technical report on the outcome of the public consultation on the draft Guidance summarises the comments received through the public consultation and presents the responses of the PLH Panel to the comments. The PLH Panel prepared an updated version of the draft Guidance taking into account the comments received. The Guidance was adopted at the PLH Panel plenary meeting on 21 June 2018, and is published in the EFSA Journal.

Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 8: suitability of taxonomic units notified to EFSA until March 2018.

The qualified presumption of safety (QPS) was developed to provide a harmonised generic pre‐evaluation procedure to support safety risk assessments of biological agents performed by EFSA's Scientific Panels. The identity, body of knowledge, safety concerns and antimicrobial resistance of valid taxonomic units were assessed. Safety concerns identified for a taxonomic unit are, where possible and reasonable in number, reflected by ‘qualifications’ which should be assessed at the strain level by the EFSA's Scientific Panels. During the current assessment, no new information was found that would change the previously recommended QPS taxonomic units and their qualifications. The Panel clarified that the qualification ‘for production purpose only’ implies the absence of viable cells of the production organism in the final product and can also be applied for food and feed products based on microbial biomass. Between September 2017 and March 2018, the QPS notification list was updated with 46 microorganisms from applications for market authorisation. From these, 28 biological agents already had QPS status, 15 were excluded of the QPS exercise from the previous QPS mandate (10 filamentous fungi and one bacteriophage) or from further evaluations within the current mandate (two notifications of Streptomyces spp. and one of Escherichia coli), and one was excluded where confirmatory data for the risk assessment of a plant protection product (PPP) was requested (Pseudomonas sp.). Three taxonomic units were (re)evaluated: Paracoccus carotinifaciens and Paenibacillus lentus had been previously evaluated in 2008 and 2014, respectively, and were now re‐evaluated within this mandate, and Yarrowia lipolytica, which was evaluated for the first time. P. carotinifaciens and P. lentus cannot be granted QPS status due to lack of scientific knowledge. Y. lipolytica is recommended for QPS status, but only for production purpose.

Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 7: suitability of taxonomic units notified to EFSA until September 2017.

The qualified presumption of safety (QPS) concept was developed to provide a harmonised generic pre‐evaluation to support safety risk assessments of biological agents performed by EFSA's scientific Panels. The identity, body of knowledge, safety concerns and antimicrobial resistance of valid taxonomic units were assessed. Safety concerns identified for a taxonomic unit are, where possible and reasonable in number, considered to be ‘qualifications’ which should be assessed at the strain level by the EFSA's scientific Panels. No new information was found that would change the previously recommended QPS taxonomic units and their qualifications. The BIOHAZ Panel confirms that the QPS approach can be extended to a genetically modified production strain if the recipient strain qualifies for the QPS status, and if the genetic modification does not indicate a concern. Between April and September 2017, the QPS notification list was updated with 46 applications for market authorisation. From these, 14 biological agents already had QPS status and 16 were not included as they are filamentous fungi or enterococci. One notification of Streptomyces K‐61 (notified as former S. griseoviridis) and four of Escherichia coli were not considered for the assessment as they belong to taxonomic units that were excluded from further evaluations within the current QPS mandate. Eight notifications of Bacillus thuringiensis and one of an oomycete are pending the reception of the complete application. Two taxonomic units were evaluated: Kitasatospora paracochleata, which had not been evaluated before, and Komagataella phaffii, previously notified as Pichia pastoris included due to a change in the taxonomic identity. Kitasatospora paracochleata cannot be granted QPS status due to lack of information on its biology and to its possible production of toxic secondary metabolites. The species Komagataella phaffii can be recommended for the QPS list when used for enzyme production.

Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 6: suitability of taxonomic units notified to EFSA until March 2017.

The qualified presumption of safety (QPS) concept was developed to provide a harmonised generic pre‐evaluation to support safety risk assessments of biological agents performed by EFSA's scientific Panels. The identity, body of knowledge, safety concerns and antimicrobial resistance of valid taxonomic units were assessed. Safety concerns identified for a taxonomic unit are, where possible and reasonable in number, reflected as ‘qualifications’ which should be assessed at the strain level by the EFSA's scientific Panels. No new information was found that would change the previously recommended QPS taxonomic units and their qualifications. Between the end of September 2016 and March 2017, the QPS notification list was updated with 87 applications for market authorisation. From these, 32 biological agents already had a QPS status, and 37 were not included in the evaluation as they are filamentous fungi or enterococci. Streptomyces species (Streptomyces cinnamonensis, Streptomyces mobaraensis and Streptomyces violaceoruber), Bacillus circulans (three notifications) and Escherichia coli (seven notifications) were re‐confirmed not suitable for QPS. Streptomyces rubiginosus and Streptomyces netropsis, not evaluated within the previous mandate, were also not recommended for QPS. Streptomyces spp. and E. coli will be excluded from further QPS evaluations within the current QPS mandate. Hyphomicrobium denitrificans, which has never been evaluated before, was not recommended for the QPS list and for Pseudomonas amyloderamosa, the QPS assessment was not applicable because it is not a validated species. Lactobacillus animalis was a new taxonomic unit recommended to have the QPS status.

Scientific Opinion on the update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA.

EFSA is requested to assess the safety of a broad range of biological agents in the context of notification for market authorisation as sources of food and feed additives, food enzymes and plant protection products. The qualified presumption of safety (QPS) assessment was developed to provide a harmonised generic pre‐assessment to support safety risk assessments performed by EFSA's scientific Panels. The safety of unambiguously defined biological agents (at the highest taxonomic unit appropriate for the purpose for which an application is intended), and the completeness of the body of knowledge are assessed. Identified safety concerns for a taxonomic unit are, where possible and reasonable in number, reflected as ‘qualifications’ in connection with a recommendation for a QPS status. The list of QPS recommended biological agents was reviewed and updated in the current opinion and therefore becomes the valid list. The 2016 update reviews previously assessed microorganisms including bacteria, yeasts and viruses used for plant protection purposes following an Extensive Literature Search strategy. The taxonomic units related to the new notifications received since the 2013 QPS opinion, were periodically evaluated for a QPS status and the results published as Statements of the BIOHAZ Panel. Carnobacterium divergens, Lactobacillus diolivorans, Microbacterium imperiale, Pasteuria nishizawae, Pediococcus parvulus, Bacillus flexus, Bacillus smithii, Xanthomonas campestris and Candida cylindracea were recommended for the QPS list. All taxonomic units previously recommended for the 2013 QPS list had their status reconfirmed as well their qualifications with the exception of Pasteuria nishizawae for which the qualification was removed. The exclusion of filamentous fungi and enterococci from the QPS evaluations was reconsidered but monitoring will be maintained and the status will be re‐evaluated in the next QPS Opinion update. Evaluation of bacteriophages should remain as a case‐by‐case procedure and should not be considered for QPS status.

Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 5: suitability of taxonomic units notified to EFSA until September 2016.

EFSA was requested to assess the safety of a broad range of biological agents in the context of notifications for market authorisation as sources of food and feed additives, enzymes and plant protection products. The qualified presumption of safety (QPS) assessment was developed to provide a harmonised generic pre‐assessment to support safety risk assessments performed by EFSA's Scientific Panels. The safety of unambiguously defined biological agents (at the highest taxonomic unit appropriate for the purpose for which an application is intended) and the completeness of the body of knowledge were assessed. Safety concerns identified for a taxonomic unit are, where possible and reasonable in number, reflected as ‘qualifications’ in connection with a recommendation for a QPS status. A total of 57 biological agents were notified to EFSA between the end of April 2016 and the beginning of September 2016. From these, 34 biological agents already had a QPS status and did not require further evaluation, and 10 were not included in the evaluation as they are filamentous fungi or enterococci, biological groups which have been excluded from QPS evaluation since 2014. Three notifications for Streptomyces violaceoruber, one for Streptomyces albus, one for Bacillus circulans and four for Escherichia coli were not evaluated for QPS status because these species were recently assessed and considered not suitable for QPS status. Therefore, only four notifications related to three taxonomic units were evaluated for QPS status. Of these, Arthrobacter ramosus and Pseudomonas fluorescens are not recommended for the QPS list. Bacillus smithii is recommended for the QPS status.
