Two-year investigation of spore-formers through the production chain at two cheese plants in Norway

Spore-forming bacteria are the most complex group of microbes to eliminate from the dairy production line due to their ability to withstand heat treatment usually used in dairy processing. These ubiquitous microorganisms have ample opportunity for multiple points of entry into the milk chain, creating issues for food quality and safety. Certain spore-formers, namely bacilli and clostridia, are more problematic to the dairy industry due to their possible pathogenicity, growth, and production of metabolites and spoilage enzymes. This research investigated the spore-forming population from raw milk reception at two Norwegian dairy plants through the cheesemaking stages until ripening. Samples were collected over two years and examined by amplicon sequencing in a culture independent manner and after an anaerobic spore-former enrichment step. In addition, a total of 608 isolates from the enriched samples were identified at the genus or species level using MALDI-TOF analysis. Most spore-forming isolates belong to the genera Bacillus or Clostridium, with the latter dominating the enriched MPN tubes of raw milk and bactofugate. Results showed a great variation among the clostridia and bacilli detected in the enriched MPN tubes. However, B. licheniformis and C. tyrobutyricum were identified in all sample types from both plants throughout the 2-year study. In conclusion, our results shed light on the fate of different spore-formers at different processing stages in the cheese production chain, which could facilitate targeted actions to reduce quality problems.

Knowledge of Production Conditions and the Quality of Raw Milk Produced in Burundi

In Burundi, despite the socio-economic importance and health impact of milk and dairy products, few researchers are interested in this sector. The few studies concerning the sector are related to the increase in the productivity of dairy cows. However, among all the actions that promote the development of the dairy sector, the improvement of the quality of dairy products constitutes an added value. In view of the above, the objective of this study is to know the production conditions and the quality of raw milk produced in the communes of Kayanza, Ngozi and Bubanza provinces and at the point of reception of raw milk of the Modern Dairy Burundi industry. To this end, a surveys were conducted in 40 dairy farms and carried out physico-chemical measurements on 84 samples of raw milk. The results revealed satisfactory hygiene in 40 farms monitored. The averages were: (i) fat: 46 ± 4g / l, (ii) protein: 29.9±4.7g/l, (iii) pH: 6.7 ± 0.07, (iv) density: 1.031 ± 0.006 and (v) lactic acidity: 16.63 ± 0.92 °D. The antibiotic residues were found in 9 of the 84 samples analyzed, 4 out of 84 samples were positive for alcohol test. It should be remembered that the presence of antibiotic residues in raw milk is an obstacle to processing, especially in the fermentation process. This study aims to contribute to the awareness of stakeholders to adopt good practices throughout the milk production chain in Burundi to better protect the health of consumers.

Renewable Horizons: Solar Power and Dairy Industry in India

Renewable energy is energy obtained from sources that are essentially inexhaustible such as wind power, solar power, geothermal energy, tidal power, bio-energy and hydropower. It is also known as non-conventional energy. Harnessing renewable energy offers numerous environmental benefits, including mitigating climate change, reducing air pollution, conserving natural resources, and enhancing energy security by diversifying energy sources. Solar resources are available in every country and both Solar Photovoltaic (SPV) and Concentrating Solar Power (CSP) technologies can be used to convert solar resource into electricity. SPV can use both direct and diffuse sunlight to generate power, while CSP relies on direct sunlight, restricting its deployment to areas with high Direct Normal Irradiance (DNI). Mandatory demand supported with higher subsidies for green technologies will positively attracts dairies towards use of solar energy. In many villages, power cut hinders the reception of milk from milk producers as electronic weighing system and milk testing instruments require uninterrupted power supply. solar-powered dairy operations offer resilience against power outages and fluctuating energy costs, empowering farmers with greater control over their operations. As the Indian dairy industry embraces solar power, it not only secures a greener future but also fosters economic growth and energy access in rural communities, marking a significant stride towards sustainability and self-sufficiency.

Tracking microbial quality, safety and environmental contamination sources in artisanal goat cheesemaking factories

A harmonised microbiological survey was performed in two artisanal factories of raw goat milk cheeses (A and B) located in the Andalusian region (Spain). A total of 165 different control points or samples (raw materials, final products, food-contact surfaces [FCS], and air) were examined as microbial and pathogen sources of contamination of artisanal goat raw milk cheeses. For raw milk samples analysed from both producers, the concentrations of aerobic-mesophilic bacteria (AMB), total coliforms, coagulase-positive Staphylococcus spp. (CPS), lactic-acid bacteria (LAB) and moulds and yeasts ranged between 3.48 and 8.59, 2.45–5.48, 3.42–4.81, 4.99–8.59 and 3.35–6.85 log cfu/mL respectively. For the same microbial groups, the analysis of raw milk cheeses revealed concentrations ranging from 7.82 to 8.88, 2.00–6.82, 2.00–5.28, 8.11–9.57 and 2.00–5.76 log cfu/g, respectively. Although the raw material analysed from producer A presented higher microbial loads and between-batch variability, it was B the producer with the most loaded final products. Regarding the microbial air quality, the fermentation area, storage room, milk reception and packaging room were the most AMB loaded places, while the ripening chamber was the area with higher fungal loads in bioareosol from both producers. Conveyor belts, cutting machine, storage boxes and brine tank were highlighted as the most contaminated FCS evaluated. Staphylococcus aureus was the only pathogen detected within the set of 51 isolates from samples as revealed by MALDI-TOF and molecular PCR, with a prevalence of 12.5% for samples from the producer B. The public health risk attributed to the consumption of artisanal goat cheese should not be neglected, and may consider the whole cheesemaking processing chain, from microbiological quality of raw milk to the ready-to-eat final product, especially concerning the presence of S. aureus.

Cross-breastfeeding and milk donation in Brazil.

The objective of this study was to describe the frequency of cross-breastfeeding, human milk donation to human milk banks and reception of human milk from human milk banks, and to investigate the intersection between cross-breastfeeding and breast milk donation practices. This study used data from the national household-based survey Brazilian National Survey on Child Nutrition (ENANI-2019), which collected information from 14,558 children < 5 years old between February 2019 and March 2020. The present study included data from 5,831 biological mothers who reported having breastfed their child < 2 years old at least once and replied questions about cross-breastfeeding, donation and recaption of human milk to human milk banks. Prevalence and 95% confidence intervals (95%CI) were estimated for each stratifier, considering the study complex sample design. Among mothers of children < 2 years old who breastfed their child at least once, 21.1% practiced cross-breastfeeding; breastfeeding another child was more frequent (15.6%) than allowing a child to be breastfed by another woman (11.2%). Among this population, 4.8% of women donated human milk to a human milk bank, and 3.6% reported that their children had received donated human milk. The donation of human milk is a practice recommended by the Brazilian Ministry of Health and has the potential to save thousands of newborns throughout Brazil. In contrast, cross-breastfeeding is contraindicated due to the potential risk of transmitting HIV. There is a need for a broad debate on these practices in Brazil and worldwide.

Carbon Footprint of Milk Processing: A Life Cycle based Approach

This study was undertaken with the aim to assess and enumerate direct and indirect CO2 emissions from Student Training Dairy Plant, WSDT, using an LCA approach. One litre of milk was chosen to be the functional unit and the operations from milk reception to packaging were considered to be the system boundary for the research. The activity level for Life Cycle Inventory was collected by consulting the personnel at the plant and the data registries available at the plant and the emission factors for the various sources were taken from various international registries such as IPCC and NDRC. The results showed that the indirect emissions contributed the most to the overall carbon emissions, i.e., 19.675 KgCO2 e. The LCIA showed the Global Warming Potential of Indirect emissions to be higher than direct emissions.

The application of Failure Mode Effects Analysis in the long supply chain – A case study of ultra filtrated milk cheese

A long food supply chain is a complex food path from producer to consumer in which multiple participants are involved, and in which various failures for both food safety and food quality can be identified. The purpose of this study was to apply the Failure Mode Effects Analysis (FMEA) technique to analyze various aspects of industrial production of cheeses produced from ultra-filtered milk (UF cheeses). Data were obtained from three dairy farms, three big dairy companies, and three trade organizations located in Serbia. Risk Priority Numbers (RPN) were calculated to rank the risk of failures identified at each production step. The obtained results showed that the greatest risks are related to the production at the dairy farms as well as the reception of raw milk at dairy processing plants, being failures that are not noticed at the primary production step. They have been covered by dairies implemented HACCP based food safety management system, which significantly reduces the risk level. The applied FMEA methodology indicates the importance of preventive food safety measures within the whole chain. Also the role of the state in improving the quality of raw milk should be emphasized. The results of this study can be used to improve the status of dairy farms in terms of animal health and welfare, but also for the identification and assessment of most common failures at dairy processing plants, and transportation and cold storage phase during retail.

Milk reception in a time-efficient manner: A case from the dairy processing plant

The short raw milk lifespan is a matter of concern for the dairy processing sector. It is crucial to the final product quality to ensure that raw milk will reach the cooling facility without undue delay while maintaining high hygienic standards. However, an effective milk reception is undermined by numerous internal and external challenges due to the complexity of the dairy manufacturing system and the stochastic variation of the milk supply chain. This work presents an industrial case study where the milk reception performance was examined, and opportunities for improvement were identified. The output provided operational documentation of each stage of milk reception. The outcomes illustrate that existing infrastructure and operations were not set up to manage a post-quota abolition uptake in milk production. A number of shortcomings and challenges were outlined, namely process bottlenecks, inefficient design of the facility layout, lack of standardized procedures, and internal-communication issues. Recommendations for improvements have been provided to achieve a 23.4% reduction of process lead time. These findings provide an opportunity for the industry to review their milk reception operations to deal with stochastic variations in milk supply and seasonality.

Prevalence of Bovine Leukemia Virus (BLV) and Bovine Adenovirus (BAdV) genomes among air and surface samples in dairy production

We aimed to assess the occurrence of bovine viruses (bovine leukemia virus–BLV and bovine adenovirus–BAdV) at workplaces in traditional dairies and to evaluate the potential role of airborne and surface contamination in spreading of these viruses derived from raw milk. The total amount of 122 samples—including 37 air (bioaerosol), 40 surface, and 45 milk samples—were checked for the presence of BLV and BAdV genomes using RT-qPCR/qPCR method. The study showed that the viruses were present in 7 air (among them 71.4% were BLV-positive and 28.6% were BAdV-positive), 14 surface (among them 85.7% were BLV-positive and 14.3% were BAdV-positive), and 34 milk (all were BLV-positive only) samples. Statistical analysis revealed that both the air and surfaces in studied occupational environment were more frequently contaminated with BLV than with BAdV (Chi-square test: p = 0.002, Fisher’s Exact test: p = 0.002). Kruskal-Wallis tests showed significant differences in BLV genome concentrations in the air (p = 0.045) as well as in BLV and BAdV genome concentrations on surfaces (p = 0.005 and p = 0.040, respectively) between studied processing areas. In units of genome copies (gc) per area, the highest concentrations of BLV and BAdV genomes in the air (9.8 × 101 ± 1.14 × 102 gc/m3 and 5.4 × 101 ± 9.1 × 101 gc/m3, respectively) and on surfaces (9.83 × 102 ± 7.41 × 102 gc/100cm2 and 2.30 × 102 ± 3.8 × 102 gc/100cm2, respectively) were observed in milk reception area. The air and surfaces of pre-production zones were also significantly more contaminated with BAdV genomes compared to production areas (Mann-Whitney test: p = 0.039 and p = 0.029, respectively). This study showed that dairy workers may be exposed to bovine viruses through the inhalation of bioaerosols and contact with contaminated surfaces. To reduce the probability of virus transmission from the raw milk to humans, efficient surface cleaning procedures degrading viral particles should be introduced and the use of personal protection equipment, especially within pre-production zones, should be required. As the raw milk may be a source of bovine viruses, the development of strategies for both the control and eradication of BLV and BAdV among cattle seems to be also urgently needed.

Perpetua, Cheese, and Martyrdom as Public Liturgy in the Passion of Perpetua and Felicity

In a well-known scene from the Passion of Perpetua and Felicity, Perpetua has a vision in which she is given cheese by a heavenly shepherd. This paper argues that the cheese which Perpetua receives is eucharistic, and that the vision is best understood as a heavenly rite of initiation. Scholarly views of the reception of cheese as essentially interchangeable with the reception of milk cannot be supported. Perpetua’s cheese should be interpreted as eucharistic even if it does not reflect any actual liturgical practice involving cheese, as both textual and contextual evidence make a eucharistic reading compelling. The biblical images in the vision, including the transformation of milk into cheese, support this liturgical reading. The article concludes by arguing that the Passio as a whole envisions martyrdom as a public liturgy.

Interpretation of Evidence-based Guideline: Berastfeeding of Neonates in the Hospital: in-hospital management

At present, the situation of breast feeding for hospitalized newborns in China is not optimistic. The management of breast feeding involves many aspects, including hospital management, medical staff and chidren families. Breastfeeding and management of hospitalized newborns face many challenges. This study aims to interpret the contents of in-hospital management such as breast milk reception, thawing, feeding and quality control in the Evidence-based Guideline: Breastfeeding of Neonates in the Hospital published in 2018, and expects to play a positive role in promoting breast-feeding of newborn in China. Key words: Infant, newborn; Hospitalization; Breast feeding; Guidebooks; In-hospital management

Detection of antibiotic residues in locally raw milk by using high performance liquid chromatography at different seasons and the effect of heat treatment on their concentration

The aim of this study was to determine the level of antibiotics residues in the locally produced cows raw milk as well as to evaluate the effect of different commercial heat treated process on the level of antibiotics residues in milk. A total of 52 locally produced milk samples were collected from apparently healthy cows in AL-Fudhailia village, milk cans (50 Kg), bulk milk tanks (1, 5 and 10 tons) which belonged to the milk reception and collection centers and dairy plants in Baghdad were collected during beginning of December 2015 to the end of April 2016. Results revealed by using high performance liquid chromatography that there was a significant seasonal variation in the residual concentration of each detected antibiotic in milk samples, where it was found that all cow's milk samples had significantly higher concentrations of antibiotic residues in spring than in winter seasons. Generally by excluding both the season and the kind of antibiotic, it was found that milk samples that were collected from 50 Kg milk cans recorded significantly highest antibiotic residues followed by bulk milk tanks of 1 and 5 tons in comparison to 10 tons. Antibiotics recovery experiment was conducted by spiking the bovine milk samples with Known concentrations four ß-lactams (Benzylpencillin, Cloxacillin, Amoxcilin, Ampcilline) and other five detected antibiotics and then exposed to one of the three different commercial heat treatments. The results showed that the pasteurization process (63°C/30 min.) a slight inactivation of four ß-lactams and other five detected antibiotics, whereas 80°C/5 min. high degree of antimicrobial loss at the rate of 89% and 82%. However, boiling at 100°C/5 min, high degree of antimicrobial loss at the rate of 100% and 90% respectively.

Computational Simulation Model of Milk Production Process, Case Study: Dairy Plant FCP-ESPOCH

Abstract. Computational simulation is a powerful tool that allows the experimentation of variants in production environments, which made on real scenarios, would entail heavy costs for the company. For this, it is necessary to correctly define the model that represents the actual processes involved. This paper presents the development of a computational simulation model, developed with "Siman" programming language and "Arena" software, based on queuing theory for the processes of milk production process in the Dairy Plant FCP-ESPOCH. We sought to determine the efficiency of the computational model using the scientific method, techniques of descriptive statistics and hypothesis demonstration. The results indicate that the data of the model are similar to the real ones in the processes of Daily Crude Milk Reception and Production Daily Pasteurized Milk, concluding that the computational model is valid for future experimentation.

Short communication: Snapshot of industry milk hauling practices in the western United States

The Pasteurized Milk Ordinance (PMO) mandates milk hauling sanitation and operational practices; however, the use of vague language (i.e., "as needed") and gaps in processes lead to variability in industry practices. Our aim was to characterize industry milk hauling practices and identify areas that may be an unexplained source of contamination in the dairy processing continuum, and communicate this information with industry to cultivate best practices. The objectives of this study were to (1) survey industry hauling sanitation and operation practices in the Pacific Northwest region of the United States, and (2) quantify microbial populations [aerobic plate count (APC), lactic acid bacteria, coliforms] on the internal surfaces of transfer hoses (tanker and receiving bay) to determine their potential contribution to the microbiological quality of raw milk. Eleven facilities (78% response rate) participated in our survey. All facilities surveyed were compliant with the PMO; however, overall milk reception layout, sanitation practices, and routine maintenance greatly varied between facilities. Farm hose samples (n = 115) had significantly higher microbial loads (APC: mean 4.7 log cfu/100 cm2; median 5.1 log cfu/cm2) than receiving hose samples (n = 57; APC: mean: 2.1 log cfu/100 cm2; median 1.9 log cfu/100 cm2). Microbial populations on transfer hose surfaces did not correlate with time since last cleaning for either tanker or receiving bay hoses. Microbial content of farm hoses is likely to reflect the microbial quality of the previous milk transferred through the hose, making on-farm management practices the primary consideration to maintain low microbiological counts downstream. Upon arrival at the processor, 10% of farm hoses were missing caps. Although this did not correlate with elevated microbiological counts, uncapped farm hoses are exposed to the farm environment, provide opportunity for contamination, and are in violation of the PMO. Through observations made during our studies, manual cleaning procedures appear to be a major weakness in hauling practices and need more attention. Recognizing and communicating variability and areas of weakness allows industry to elevate their hauling sanitation and operational practices to maintain optimum milk microbiological quality.

Got Jewish Milk? Screening Epstein and Van Sant for Intersectional Film History

Rob Epstein's The Times of Harvey Milk (USA, 1984) and Gus Van Sant's Milk (USA, 2008), the two major films that narrate the life and tragically dramatic death of gay politician and activist Harvey Milk (1930–1978), are widely recognized as part of the queer cinematic canon but are less often categorized as Jewish films. While Epstein's film adroitly presents a Kosher-style Milk, the Jewishness of Van Sant's Milk is less certain; however, a well-established pattern of gay and lesbian Jews citing Milk as one of their own—what I term Jewqhooing—enabled a Jewish reception of Milk . Querying and queerying the Jewishness of Milk (the man as well as the movies that purport to represent his life and times) illuminate the complex ways Jewishness continues to be cinematically conveyed or whitewashed as well as the intersections between queer and Jewish film history.

Application of exergy analysis to the dairy industry: A case study of yogurt drink production plant

This work was aimed at undertaking a detailed exergy analysis of an industrial-scale yogurt drink production plant using actual operational data. Exergy efficiency and exergy destruction rate of each subcomponent of four main subsystems of the plant, including steam generation, above-zero refrigeration, milk reception, pasteurization, and standardization, and yogurt drink production lines were derived independently. This analysis was performed to quantify thermodynamic inefficiencies of all subcomponents of the plant in order to identify the breakthrough points for further energy savings. An effort was also made to compute the quantity of exergy destruction in processing a given amount of pasteurized yogurt drink. The results indicated that the highest exergy destruction rate occurred in the boiler & compressor combination of steam generator, followed by ice-water tank & agitator combination in the above zero refrigeration system. The specific exergy destruction of pasteurized yogurt drink was determined as 442kJ/kg according to the mass allocation method. The steam generator had the highest contribution to the specific exergy destruction of pasteurized yogurt drink, followed by yogurt drink production, above-zero refrigeration, and milk reception, pasteurization, and standardization lines, respectively. In general, the current survey can be an important step for future improvements of dairy processing plants from the sustainability and productivity viewpoints. This study clearly showed the effectiveness of exergy analysis for determining irreversibilities and losses occurring in dairy processing plants in order to improve their thermodynamic performances.

Draining and salting as responsible key steps in the generation of the acid-forming potential of cheese: Application to a soft blue-veined cheese

A disregarded nutritional feature of cheeses is their high acid-forming potential when ingested, which is associated with deleterious effects on consumers’ health. This work aimed to characterize the acid-forming potential of a blue-veined cheese during manufacturing to identify the main steps of the process involved in this phenomenon. Sampling was performed on 3 batches at 10 steps of the cheese-making process: reception of raw milk, pasteurization, maturation of milk, coagulation, stirring, draining of the curds, and 4 ripening stages: 21, 28, 42, and 56d. The acid-forming potential of each sample was evaluated by (1) the calculation of the potential renal acid load (PRAL) index (considering protein, Cl, P, Na, K, Mg, and Ca contents), and (2) its organic anion content (lactate and citrate), considered as alkalinizing elements. Draining and salting were identified as the main steps responsible for generation of the acid-forming potential of cheese. The draining process induced an increase in the PRAL index from 1.2mEq/100g in milk to 10.4mEq/100g in drained curds due to the increase in dry matter and the loss of alkaline minerals into the whey. The increase in PRAL value (20.3mEq/100g at d 56) following salting resulted from an imbalance between the strong acidogenic elements (Cl, P, and proteins) and the main alkalinizing ones (Na and Ca). Particularly, Cl had a major effect on the PRAL value. Regarding organic anions, draining induced a loss of 93% of the citrate content in initial milk. The lactate content increased as fermentation occurred (1,297.9mg/100g in drained curds), and then decreased during ripening (519.3mg/100g at d 56). This lactate level probably helps moderate the acidifying potential of end products. Technological strategies aimed at limiting the acid-forming potential of cheeses are proposed and deserve further research to evaluate their nutritional relevance.

Exergetic performance assessment of a long-life milk processing plant: a comprehensive survey

The aim of this study was to carry out a comprehensive exergy analysis of an industrial-scale long-life milk processing plant for the first time. The plant consisted of four main lines including steam generator, above-zero refrigeration system, milk reception, pasteurization, and standardization line, and ultra-high-temperature (UHT) milk processing unit. This survey was performed to obtain more in-depth information about the exergy destroyed in the whole plant and its main subcomponents. In addition, an attempt was made to quantify the exergy destroyed for processing a given amount of the long-life milk using the mass allocation method. The results indicated that the largest exergy destruction rate occurred in the compressor and boiler combination of the steam generation system, accounting for 89% of the total exergy destruction of the system. More specifically, the specific exergy destruction of the long-life milk processing was determined as 345.50 kJ kg−1. The steam generation system had the greatest contribution to the specific exergy destruction of the long-life milk processing followed by above-zero refrigeration system, UHT milk processing unit, and milk reception, pasteurization, and standardization line, respectively. Hence, a small improvement in the exergetic performance of the steam generator could profoundly lower the specific exergy destruction of the long-life milk processing. According to the outcomes of the current study, the performance and sustainability parameters of dairy processing plants can be best-evaluated and improved using exergy analysis.
