Quantum dot-based biomimetic fluorescence immunoassays for enrofloxacin detection in animal-derived foods.

Long-term consumption of foods with excessive enrofloxacin (ENRO) residues may cause the accumulation of ENRO in the human body, thus damaging human health. In this study, quantum dot-based biomimetic fluorescence immunoassays were used for enrofloxacin detection in food of animal origin. Under the most suitable conditions, the detection limit (IC15) of the method in standard solution was 0.13 ± 0.02 ng L-1 and the sensitivity (IC50) was 0.13 ± 0.18 μg L-1. The recoveries for ENRO from four fortified food samples, including chicken, eggs, shrimp, and milk, ranged from 85.74% to 114.19% and the coefficients of variation were 0.01-18.09%. The established method shows good agreement with the results obtained using commercial ELISA kits, with a correlation coefficient of 0.997. The proposed method shows the advantages of high sensitivity, specificity and wide detection range. It can be used as an alternative method for the rapid and sensitive detection of ENRO in food of animal origin.

Classifiability analysis of spectroscopic profiling datasets in food safety related discriminative tasks.

Discriminative tasks, i.e., the identification of different food materials, brands, and origins, have become an essential part of food safety control. In recent years, spectroscopic profiling combined with machine learning is becoming popular for food-related discriminative tasks, but finding an appropriate classification model can be challenging. Compared to the current "trial-and-error" practice, this paper proposes a dedicated two-step classifiability analysis framework to address this issue. The first step collects more than 90 diversified metrics to measure the dataset separability from different perspectives. The second step synthesizes these metrics into a quantitative score using meta-learner and decomposition-based strategies. Finally, two Raman spectroscopic profiling case studies were conducted to validate the method, demonstrating higher scores for the easily separable liquor dataset (around 1.0) compared to the more challenging table salt dataset (< 0.5). This score can guide researchers to determine the required model complexity and assess the adequacy of the current physio-chemical profiling instrument. We expected the classifiability analysis framework proposed in this research to be generalized to a wide range of machine learning applications within the realm of food, where data-driven classification or discriminative tasks are involved.

Ethnic fermented foods of the world: an overview

AbstractThe origins of traditional fermented foods and the types and characteristics of fermented foods by region are reviewed. Fermented foods are classified into alcohol fermentation, acid fermentation, carbon dioxide (bread) fermentation, and amino acid/peptide fermentation, and related fermentation technologies for each region are introduced. The raw materials, microorganisms involved, and usage of ethnic fermented foods are reviewed and compared one another. The beginning of food fermentation technology is related to the invention and use of earthenware, and Northeast Asia is presumed to be one of the birth places. During the period of primitive pottery culture (8000–3000 BCE) on the Korean Peninsula and the coastal region of Korea Strait, boiling technology of food materials using pottery and salt manufacturing technology from seawater were developed, and at the same time, alcohol fermentation using grains and salt-fermentation of fish and vegetables emerged. In the West, where people were nomads, a roasting/grilling culture was continued for a long time, and technologies for fermenting fruit wine and milk products such as cheese and yogurt were developed. As a result, fermentation was mainly used for enhancing the taste of plant foods in the East, while for extending the shelf life of animal foods in the West. The production of salty and meaty flavors from soybeans and marine products by fermentation in East Asia is a technology that increases the value of low-quality proteins.

Особливості харчування українців в умовах геноциду 1932–1933 рр. (на основі спогадів очевидців Голодомору)

Based on 155 accounts of the Holodomor witnesses (covering the whole USSR territory), the author comprehensively studied the peculiarities of the diet of Ukrainians in the conditions of the crime of genocide committed by the communist totalitarian regime in 1932 and 1933. The traditional diet of Ukrainians was before the 1930s was described. It is known that that since ancient times, Ukrainians were primarily involved in agriculture, as well as cattle breeding and gathering, which determined the traditional diet of the nation, whose daily ration consisted of food of plant and animal origin. From the products of plant origin, they cooked cereal and vegetable dishes (bread, halushky, zatirka, noodles, porridge, kulish, chur, solomakha, mamalyha, lemishka, borsch, yushka, soup, cabbage soup, potatoes, pancakes, hashbrowns, dumplings), and from the products of animal origin, they cooked meat, dairy and fish dishes (sausages, blood sausages, roast, saltyson, kholodets, dushenyna, kruchenyky, sichenyky, khliaka, riazhanka, butter, sour cream, cheese, etc.). The most important dish on the table of Ukrainians was and still is bread. It has been analyzed and proved that during the Holodomor genocide years, the destruction of traditional Ukrainian nutrition, along with customs and traditions related to it took place. The communist totalitarian regime, by taking away all edible supplies, doomed Ukrainians to hungry death. To survive, Ukrainians ate surrogates, plants (leaves, weeds, grass); small animals, insects, birds (hedgehogs, cats, dogs, gophers, sparrows, crows, pigeons, storks, frogs, mollusks, snails, dragonflies); cow’s milk (families that had a cow called it a feeder and a savior); vegetables, fruits, berries; rotten potatoes, beets (dug up in early spring); offal; human flesh (cases of corpse-eating and cannibalism were recorded). Consumption of such products caused the most severe stomach diseases and even fatal poisonings. People suffered from vomiting, diarrhea, swelling, weakness, inflammation, and unbearable pain. Epidemics and various diseases, often fatal ones (smallpox, dysentery, louse-borne typhus and typhoid fever, malaria, pellagra, glanders, dropsy) spread in Ukraine Due to hunger, Ukrainians developed mental disorders, their consciousness was clouded, their thinking, will, and memory were disturbed, and their behavior changed. Keywords: Holodomor, 1932–1933, genocide, non-traditional food, surrogates, moral and psychological effects.

Decreasing the carbon footprint of food through public procurement—A case study from the municipality of Härnösand

Eating habits are among the strongest drivers of negative environmental impact. Public procurement has been suggested as an efficient lever to catalyze changes within the food system. This study examines alternative purchase processes that may decrease the carbon footprint of publicly procured food through a case study of a municipality in the Northern part of Sweden. The GHG emissions associated with the current food service in the case study were 2.2 kg CO2e per kg food and must be reduced by 40.9% by 2030 to comply with the Paris Agreement; 76% of the emissions derive from food of animal origin (44% from unprocessed red meat). Three alternative diet scenarios, “zero red meat,” “−50% red meat,” and “flexitarian free from red meat,” were explored. Only 6% of the total purchased food kilograms were altered, yet the cutback of meat caused GHG emissions reductions turned out to be as high as 44%. The Swedish Law on Public Procurement, deficient infrastructure, unsustainable food culture, and local politicians' reluctance to change were mentioned as the main obstacles to materializing necessary changes in the food procurement system. The respondents also pointed out essential policy changes at the national and municipal levels.

Identification of Bacterial Pathogens in Organic Food of Animal Origin in Poland.

The consumption of organic food has increased in recent years. In organic rearing animals are exposed to outdoor conditions, which may increase their risk of infection from various pathogens. In the present study the occurrence of the most significant foodborne pathogenic bacteria in organic meat and ready-to-eat organic meat products was assessed. Out of 100 raw organic meat samples tested, 72 were contaminated with bacterial pathogens. The highest percentage of contaminated samples was observed in poultry meat (92.5%) followed by pork meat (66.7%). Furthermore, 50.0% of beef origin samples were positive for the bacteria tested. L. monocytogenes was found in 39.0% of samples, S. aureus was identified in 37.0%, Campylobacter in 20.0%, Salmonella in 8.0% and Shigatoxin-producing E. coli in 4.0% of raw meat samples. In 31.0% of samples a co-occurrence of two (83.9%) or three (16.1%) pathogens was observed. Among 100 samples of organic meat products tested, only L. monocytogenes was found in 5.0% of samples. The result of the present study indicated that organic food may be a source of harmful microorganisms that may pose foodborne infections to consumers.

Sosialisasi Manajemen Kesehatan Kambing Perah serta Pengaruhnya terhadap Kualitas Susu pada Peternak Kambing Perah di Kecamatan Ampelgading dan Tirtoyudo Kabupaten Malang

Goat's milk is a food of animal origin that is easily damaged and requires handling after the milking process. Ampelgading and Tirtoyudo sub-districts are areas in Malang Regency where some of the population are dairy goat breeders. This community service aims to provide socialization and education on good animal health management so that it can improve the quality of goat milk. The activity began with collecting farmer data and analyzing the situation of dairy goat farming. The socialization method was carried out by conducting focus group discussions about knowledge of animal health management and checking the quality of goat milk. Milk composition testing uses Lactoscan, while organoleptic testing is based on Indonesian National Standard 01-2346-2006 concerning organoleptic and sensory testing instructions. The results of community service show that the quality of dairy goat milk in Ampelgading and Tirtoyudo Districts is premium based on the Thailand Agriculture Standard 2008. The results of the organoleptic test of goat milk have remained the same based on SNI 3141-1-2011 regarding the quality of fresh milk. The results of this goat milk quality test can be used as a basis for farmers to improve livestock management and milking. Through this activity, farmers can implement good livestock health management so that the quality of goat milk and the selling price increase. This activity will encourage young farmers to be more interested in becoming dairy goat breeders who have high economic prospects and contribute to increasing goat milk productivity. Apart from that, this activity can improve the welfare of farmers by improving the quality of goat milk with higher selling power.

Reducing the danger of phytopathogen toxins by using an organomineral composition

Relevance. Contamination by toxins of phytopathogens or mycotoxins of food and feed raw materials of plant origin poses a serious threat to the production of high-quality and safe agricultural products. Reducing the risks of contamination of plant raw materials with mycotoxins depends on the effective use of biological products to reduce the toxicity of mycotoxins.Methods. Experiments were carried out on primary rat liver cells. Primary liver cells were cultured in DMEM medium in the presence of 10% fetal calf serum at 37OC and 5% CO2. Zearalenone and T-2 toxin were dissolved in a mixture of DMSO and 96% alcohol in a ratio 1:1. Zearalenone T-2 toxin and protective compositions were mixed and aged together for 6 hours and after exposure added to a medium with a cellular monolayer. The concentration of bacterial-based compositions KMBI-3 and KMCI-3 was used for research in three variants: 0.4 mg/ml, 2 mg/ml, 4 mg/ml. After 24 hours of cultivation, the cell layer was evaluated using an inverted microscope according to the following parameters: percentage of surface coverage, cell shape, number of cell aggregates, number of floating cells.Results. A dose-dependent decrease in cell viability was revealed when exposed to zearalenone and T-2 toxin, the most toxic effect was observed at doses from 0.5 х 10-4 and 8.6 х 10-8 M and 2.14 х 10-7 M, respectively. When using the protective composition KMBI-3 at a dose of 4 mg/ml, the least negative effect of zearalenone and T-2 toxin on cell culture was observed. The use of compositions of organomineral origin KMBI-3 helps to increase cell viability when exposed to the toxins zearalenone and T-2 toxin, which indicates the activation of proliferative processes in comparison with the group without the use of drugs. The use of the biopreparation KMBI-3 reduces the pathogenic effect of zearalenone and T-2 toxin on cell culture, increases the resistance of liver cells to the effects of phytopathogen toxins.

Knowledge, attitude and practices towards antibiotic usage among farmers rearing yaks, dzomo and hill cattle in the high-altitude regionsof Himachal Pradesh

The present cross-sectional survey aimed to investigate knowledge, attitudes and practices (KAP) of farmers of high altitude regions of Himachal Pradesh towards antibiotics and their usage. The survey was carried out using pre-validated questionnaires among 162 farmers (40 males and 122 females) engaged in animal husbandry practices particularly rearing yaks, dzomo and hill cattle from Lahaul, Spiti and Kinnaur regions of Himachal Pradesh. More than 75% of the respondents were aware of antibiotics, with females (83.6%) having more knowledge in comparison to males (52.5%). Using antibiotics in lactating animals may lead to, occurrence of antibiotics or their residues in milk, question was correctly answered by 110/162 (67.91%) respondents with significant difference with respect to educational levels. It was observed that 78.68% respondents adopted the best practice of not purchasing antibiotics without prescription. Overall, it was found that farmers’ perceptions of the use of antibiotics and their side effects are directly influenced by their education. Majority of the farmers were having significant knowledge regarding antibiotics, their usage and effects on consumers. They also had very positive attitude towards antibiotic usage but the practices were average in context of purchasing of antibiotics without prescription and consumption of milk from animals undergoing treatment. Therefore, education of farmers on food safety and antibiotic misuse becomes imperative for production of good quality animal origin foods.

Consumers’ Willingness to Pay for Attributes of Sustainability, Origin and Production Process in Raicilla

In recent years, consumer concern about the origin, process and environmental impact of food and beverages has increased significantly, due to sustainability and food safety issues. However, studies of consumers’ willingness to pay for these types of attributes in traditional agave distillates are scarce. In this article, a discrete choice experiment was carried out on a sample of Mexican Raicilla consumers (n = 300) to estimate their willingness to pay for attributes such as ecolabels, protections of origin and the production process; the analysis was performed using a mixed logit model. The results showed that consumers are willing to pay a higher price for a Raicilla that contains on the label the region of origin, the production process (ancestral or artisanal), that has some legal-economic protection, such as geographical indication or designation of origin, and certifications in water management and organic production. The methodology of discrete choice experiments made it possible to jointly evaluate the extrinsic attributes in the willingness to pay for a traditional agave distillate, allowing its influence on the decision to purchase to be determined.

Brominated flame retardant in animal feeds from Poland

The safety of food of animal origin is closely related to feed quality. Feed pollution by brominated flame retardants (BFRs) leads to the exposure of animals and consumers of food of animal origin to these substances. The study aimed to assess the concentration of ten PBDE (BDE-28, 47, 49, 99, 100, 138, 153, 154, 183, and 209) congeners and eight nBFRs (TBX, PBT, HBB, PBEB, EH-TBB, BTBPE, BEH-TBPH, and DBDPE) in 59 feed and feed materials from six different feed categories (277/2012/EU). The quantification of analytes was based on isotopic dilution and gas chromatography–high-resolution mass spectrometry (GC-HRMS). All 59 feed samples were contaminated with at least one of the analytes. PBDEs and nBFRs were found in 78% and 91% of the samples, respectively. BFR content ranged from 0.18 to 5.87 μg·kg-1 in feed with a 12% moisture content, and the most contaminated category was vegetable oils, followed by fishmeal, feeds for fish, animal fats, and compound feeds for pigs. The least contaminated samples turned out to be compound feeds for chickens. This study confirms the general trend of decreasing PBDE concentrations in fishmeal. In the investigated samples, BDE-47 and BDE-209 contributed the most to the ∑PBDE content. DBDPE, HBB, and PBT contributed the most to the investigated ∑nBFRs. The widespread occurrence of nBFRs in feed seems disturbing because these compounds have replaced PBDEs. Their concentrations in the feed may most likely exceed those of PBDEs in the coming years.

Fishy Forensics: FT-NIR and Machine Learning based authentication of Mediterranean Anchovies (Engraulis encrasicolus)

Seafood authentication and traceability is a challenging issue owing to its complex supply chain and fishing in international waters. NIR spectroscopy has been successfully used to authenticate food of animal and plant origin. In this study, FT-NIR was used to discriminate between Mediterranean anchovies (Engraulis encrasicolus) fished from Adriatic, Balearic, and Tyrrhenian Sea. The spectra were prepared using the standard normal variate (SNV) and the Savitzky-Golay 1st derivative, 2nd order (SG), as well as both together. The model was built, after outlier removal, with linear-support vector machine (L-SVM), polynomial-SVM (P-SVM), k-nearest neighbor (k-NN) and Random Forest (RF). Spectral preprocessing improved model classification accuracy for all algorithms. The data could not be put into groups by linear algorithms like L-SVM and k-NN because the NIR spectra were not linear and had many columns. Non-linear algorithms, P-SVM and RF when coupled with SG+SNV, successfully produced models with maximum robustness. P-SVM and RF models had 100% accuracy in training set and 95.7% and 95.5% accuracy in testing set, respectively and 95.2 and 95.1 accuracy in cross-validation set.

Seasonal Feeding Activity and Ontogenetic Dietary Shifts of the Common Carp (Cyprinus carpio) in Lake Arekit, a Small, Eutrophic Lake in Ethiopia

ABSTRACTSeasonal feeding activity and ontogenetic dietary shifts of Cyprinus carpio (Linnaeus, 1758) were examined using 209 fish samples from Lake Arekit, Ethiopia. Among the 209 specimens, 174 (83.3%) displayed a range of dietary items in their stomachs. The species’ feeding patterns were determined through numerical indexes (frequency of occurrence and volumetric contribution) and composite indexes (index of preponderance [IOP] and Geometric Index of Importance [GIIi]). Detritus emerged as the primary food source for C. carpio, followed by macrophytes, insects and zooplankton. A lesser amount of phytoplankton, nematodes and ostracods were also consumed. On the basis of the findings, C. carpio can be classified as a detri‐omnivore, as it consumes benthic species like nematodes, ostracods and insect larvae. Seasonal fluctuations in food item consumption were noted (p &lt; 0.05), with higher intake during the rainy season and reduced consumption in the dry season. There was a distinct ontogenetic shift in the relative importance of food items and showed significant variations in food preferences among size groups (p &lt; 0.05). The contributions of animal‐origin food categories (ostracods, zooplankton and insects) were important in the diet of the smaller size class, whereas food of plant origin (macrophytes) and detritus were more important in the diet of adults. Understanding the seasonal feeding patterns and ontogenetic dietary shifts of C. carpio in Lake Arekit provides crucial insights into their ecological role within the lake's ecosystem and highlights their adaptability to eutrophic conditions.

Safety and efficacy of a feed additive consisting of lutein-rich extract of Tagetes erecta L. for turkeys for fattening (EW Nutrition).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of lutein-rich extract of Tagetes erecta L. as sensory additive (functional group: Colourants (ii) substances which, when fed to animals, add colours to food of animal origin) for turkeys for fattening. The additive is already authorised for use in feed for chickens for fattening and minor poultry for fattening and laying hens and minor poultry for laying. The FEEDAP Panel concluded that the use of lutein-rich extract of T. erecta is safe for turkeys for fattening when used up to the maximum proposed use level of 80 mg total carotenoids/kg complete feed. The Panel concluded that the use of lutein-rich extract of T. erecta in feed for turkeys for fattening under the proposed conditions of use would not be of concern for the consumer, considering also its use in other poultry for fattening and for laying hens. Regarding user safety, the lutein-rich extract of T. erecta extract is irritant to skin and eyes and any exposure is considered a risk. The conclusions on user safety reached for the lutein-rich extract of T. erecta would, in principle, apply to preparations made with it. The use of the additive in feed for turkeys for fattening under the proposed conditions of use is safe for the environment. The FEEDAP Panel concluded that the additive has the potential to colour the skin of turkeys for fattening at the proposed conditions of use.

The gut microbiome without any plant food? A case study on the gut microbiome of a healthy carnivore

Objective The carnivore diet is a ketogenic diet based exclusively on the consumption of food of animal origin. While the impact of various diets on the gut microbiome is extensively documented, the effects of a carnivore diet remain unclear. To address this gap, we conducted a pilot study on the gut microbiome of an individual following a carnivore diet and compared it with that of a subgroup of healthy individuals. Methods A stool sample was collected from a healthy 32-year-old male adhering to a carnivore diet and was sequenced using 16S DNA Amplicon Sequencing. The results were then compared to those from three control groups possessing similar anthropometric characteristics and differing in their frequency of meat consumption. Results The gut microbiome of the carnivore was dominated by the phylum Firmicutes and the genera Faecalibacterium, Blautia, unspecific Lachnospiraceae, Bacteroides, and Roseburia—bacteria known for fiber degradation. Furthermore, neither alpha- nor beta-diversity, nor the functional capacity of the gut microbiome, showed differences when compared to the control groups. Additionally, the gut microbiome of the carnivore showed the least similarities with the microbiome of the cohort consuming meat on a daily basis. Conclusions In our study, we showcase the compositional and functional characteristics of the gut microbiome in an individual on a carnivorous diet, finding no differences in comparison to a control cohort. Further research is needed to investigate the short- and long-term impacts of a carnivorous diet on gut health through cross-sectional and longitudinal studies. Significance statement To the best of our knowledge this is the first study to report on the composition of the gut microbiome of a person adhering long-term to the carnivore diet.

Seasonal changes in body composition in children from Maya agriculturalists in central Yucatán, Mexico.

Development policies have aimed to substitute subsistence agriculture for cash crops or other cash generating activities to encourage local farmers to depend on store-bought groceries available year-round instead of seasonal subsistence crops. In this paper, we test the hypothesis that increased dependence on store bought foods has decreased seasonal changes in nutritional status and fat mass in Maya Children from Yucatan, Mexico. Weight for age (W/A), body mass index (BMI), and tricipital Skinfold z scores in children under the age of 10 years from 14 Maya rural towns with different degrees of development were compared longitudinally between scarcity and abundance seasons using a repeated measures analysis of variance. Height for age (H/A) z scores were also estimated. Origin of food consumed corresponded to the town's degree of development. Nutritional status (W/Az) and adiposity, BMI, and tricipital z scores were significantly lower during the scarcity season in every community. W/Az, tricipital skinfold z, and H/Az scores were significantly higher in developed than in traditional towns, yet in both types of town W/Az and H/Az scores were below the WHO standard mean. Tricipital skinfold z score was only below the WHO standard amongst traditional towns during the scarcity season. Increased dependence on store foods failed to eliminate significant losses in body fat during the scarcity season. This failure may be affecting linear growth and promoting a thrifty phenotype that is seen in short and stocky individuals with a tendency to accumulate fat during abundance seasons.

Europium anomaly as a robust geogenic fingerprint for the geographical origin of aquatic products: A case study of nori (Neopyropia yezoensis) from the Japanese market

Rare earth element (REE) concentration patterns, while essential in geochemistry for tracing sample histories, have yet to be utilised entirely in food origin authentication. This research analysed 13 heavy metal(oid)s and REEs in Japanese edible seaweed Nori sheet samples (Neopyropia yezoensis), showing that the concentrations mirror the laver cultivation area's geological features (island arc-trench systems vs. continental crust). Thresholds for cadmium (0.5 ppm) and thorium (3.3 ppb) differentiate Japanese products from Korean imports. The slope of REE pattern, gadolinium anomalies, and yttrium/holmium ratios were also examined. However, nori samples significantly conveyed europium (Eu) anomalies, aligning with the mariculture hinterland's geochemistry. Both Japan's major seaweed mariculture areas, the Ariake Sea and the Seto Inland Sea, and Korean imports revealed distinct Eu anomalies (Eu/Eu* = 0.81–0.90, 0.58–0.66, 0.71–0.77), underscoring the potential of Eu anomalies as reliable seafood origin verifiers. This was also confirmed by literature values of Chinese samples.

Portable detection of Salmonella in food of animal origin via Cas12a-RAA combined with an LFS/PGM dual-signaling readout biosensor.

Ahighly specific and sensitive rapid two-signal assay was developedfor the detection of Salmonella typhimurium in foods of animal origin. TheinvA gene of Salmonella was usedas the biorecognition element and recombinase-assisted amplification (RAA) technology for signal amplification. By utilizing the specific recognition and efficient trans-cleavage activity of CRISPR/Cas12a, point-of-care testing (POCT) for S. typhimurium was achieved via lateral flow strips (LFS) and personal glucometer (PGM) biosensors as dual signal readout systems, with sensitivities of 33CFU/mL and 20CFU/mL, respectively. Users can select the appropriate test system on the basis of specific application requirements: LFSs are ideal for rapid onsite screening, whereas glucometer biosensors offer precise quantitative determination. This approach simplifies the use of large instruments and overcomes site constraints, demonstrating good accuracy and applicability in animal-derived samples, with significant potential for the detection of other pathogens and for use in restricted environments.

Beyond table manners: Children’s gratitude for food and the role of parental socialization

This investigation explores children’s food gratitude and parents’ socialization of this gratitude within the United States. Study 1 examined children’s spontaneous expressions of gratitude (N = 1,441), focusing on the concepts of food environmental sustainability, properties, origins, scripts, and well-being. Study 2 surveyed parents (N = 110) regarding their engagement in socialization practices that promote children’s food gratitude: conversations; modeling; niche selection; and, scaffolding. The results unveil nuances in younger and older children’s gratitude for food concepts as well as parents’ differential use of food gratitude socialization practices and emphasis on specific concepts. Furthermore, the results demonstrate that parents’ food gratitude socialization practices predict parents’ reports of their children’s food gratitude. These studies elucidate variability in children’s gratitude for food and parents’ contribution to its development within this domain. These findings have implications for food gratitude socialization. (137 words)
