Evaluating the effects of different processing methods on the nutritional quality of bovine milk

Milk is a universal food that is widely consumed around the world irrespective of age. It has a complex matrix consisting of proteins, carbohydrates, minerals, vitamins, and enzymes that have successfully retained the interest of researchers as yet. The aim of the study was to evaluate the effect of low-temperature long-time (LTLT), ultraviolet light (UV), and ultrasound (US) treatments on physicochemical properties, microbial count, and fatty acid profiling of three types of bovine milk – Country (C), Jersey (J), and Holstein Friesian (HF). The study was conducted in southern India, where these three types of milk are commonly consumed. It was found that no significant (p ˂ 0.05) differences in the proximate composition of milk samples subjected to different treatments compared to untreated milk. However, LTLT treatment resulted in a reduction in ascorbic acid content and significant changes in antioxidant activity and lactose content. LTLT treatment was also able to kill the pathogenic bacteria E. coli, whereas UV and US treatment only showed a notable reduction in the E. coli count. Fatty acid profiling of the treated milk samples was done using GC/MS, and Fourier Transform Infrared Spectroscopy (FTIR) was performed to study the types of chemical bonds present. The results showed that non-thermal treatments (UV and US) were able to sustain the chemical characteristics of milk and had potential for implementation in the dairy industry. Overall, the study highlights the potential benefits of non-thermal treatments such as UV and US in maintaining the chemical properties of milk and reducing pathogenic bacteria count. The findings could be useful in the dairy industry to ensure the safety and quality of milk.

Consumers' willingness to pay for safe and quality milk: Evidence from experimental auctions in Rwanda

AbstractA major concern of the Rwandan government and other dairy stakeholders is the safety and quality of milk that goes through informal delivery systems until it gets to the consumers. Although the government introduced the dairy best practices scheme that stipulates standards and practices for proper handling of raw milk, consumers' willingness to pay (WTP) for such milk has not yet been assessed. It is also unclear whether consumers are aware of and/or value the safety‐ and quality‐related information on types of milk sold in different marketing channels. In this study, we use the second price auction mechanism to elicit consumers' WTP for pasteurized but unpackaged milk in Rwanda and we estimate the effect of providing safety‐ and quality‐related information on WTP using the random‐effect Tobit model. Our results show that consumers are willing to pay a price premium for safe and quality milk, implying that there is an opportunity for market transformation in the dairy sector. Furthermore, we find a positive and significant effect of providing information to consumers on WTP for safe and quality milk. Based on our results, we recommend policies that promote private sector investments in upscaling of milk zones and the establishment of milk‐dispensing machines selling this type of milk. There is also a need for information campaigns that increase consumers' knowledge and awareness of the quality of milk consumed. [EconLit Citations: C34, C91, D12, D44, M31].

Distribution of cereulide-producing Bacillus cereus in raw milk in Hokkaido, Japan, and evaluation of cereulide production

It is important to understand the distribution of strains of Bacillus cereus that produce the emetic toxin, cereulide, in raw milk, and to evaluate their impact on the safety of milk and dairy products. The distribution of cereulide-producing B. cereus was investigated for isolates from raw milk in Hokkaido, Japan, and the ability of strains to produce cereulide in milk was also studied. Only one of 393 isolates had the cereulide-producing gene, indicating very low presence of cereulide-producing strains in milk in Hokkaido. This isolate produced cereulide in milk stored at 12 and 30 °C, but not at 10 °C. It was concluded that keeping storage temperatures below 10 °C reduces the possibility of accumulation of cereulide in milk and dairy products pasteurised at temperatures at which B. cereus spores survive. Hence the possibility of occurrence of cereulide-associated vomiting by ingestion of dairy products of Hokkaido, is very low.

Evaluation of the physicochemical and hygienic quality of cow's milk and its derivatives in El Jadida city Morocco.

Despite the efforts and investments made for traceability and the guarantee of a fair and safe milk product, the informal sector threatens the safety of milk. In fact, during this circuit, the product does not undergo any treatment and therefore presents serious risks for the health of the consumer. In this context, studies have been carried out on samples of peddled milk and products derived from it. The purpose of this study is to evaluate the relevance of the informal circuit in Morocco's Doukkala region (El Jadida Province) by physicochemical and microbiological investigation of raw milk and its derivatives at various points of sale. 84 samples were taken between (23 for raw milk, 30 for the «Lben», and 31 for the «Raib») between January 1st, 2021 and October 30th, 2021. According to Moroccan rules, microbiological analyses revealed an extremely high non-compliance rate in most samples obtained at the level of outlets situated in the El Jadida region, with a non-compliance ratio of 65 percent for raw milk sold, 70 percent for the «Lben», and 40 percent for the «Raib». Likewise, these analyses revealed that majority of the samples did not fulfill international criteria for the pH values of raw milk samples «Lben» and «Raib», which are respectively between 5.85 and 6.71; 4.14 and 4.43 and 4.5. Other characteristics, including lactose, proteins, fat, mineral salts, density, and additional water, have also yielded results. This has allowed us to analyze the major impact of the peddling circuit at the regional level, which is a risk factor for consumer health.

Cold plasma bubbling: Impact on safety, physicochemical properties, and nutritional quality of sesame milk

The decline in the consumption of animal milk raises the possibility of using different plant materials in producing vegan milk. Sesame is an oilseed, rich in nutrients, making it a suitable animal milk substitute. However, microbial stability, quality, and anti-nutritional factors must be considered while processing vegan milk. In this study, plasma bubbling (PB) was used for processing sesame milk (at various exposure times-10, 20 and 30 min). PB effectively reduced the microbial load (1.82 and 0.64 log reduction of coliforms and bacterial load), yet it increased oxidation of lipids and reduction in whiteness index. However, the reduction in phytates (1.48–0.58 mg/g), oxalates (39.13–19.96 μg/g) and lipoxygenase activity (18.3 from 100%) makes it an efficient alternative technique in the processing of sesame milk. Further, studying the structural modifications of protein and lipids would be beneficial in understanding plasma influence in the processing of sesame milk.

Hemodynamic Changes with Umbilical Cord Milking in Nonvigorous Newborns: A Randomized Cluster Cross-over Trial

To assess the hemodynamic safety and efficacy of umbilical cord milking (UCM) compared with early cord clamping (ECC) in nonvigorous newborn infants enrolled in a large multicenter randomized cluster-crossover trial. Two hundred twenty-seven nonvigorous term or near-term infants who were enrolled in the parent UCM vs ECC trial consented for this substudy. An echocardiogram was performed at 12±6hours of age by ultrasound technicians blinded to randomization. The primary outcome was left ventricular output (LVO). Prespecified secondary outcomes included measured superior vena cava (SVC) flow, right ventricular output (RVO), peak systolic strain, and peak systolic velocity by tissue Doppler examination of the RV lateral wall and the interventricular septum. Nonvigorous infants receiving UCM had increased hemodynamic echocardiographic parameters as measured by higher LVO (225±64 vs 187±52mL/kg/min; P<.001), RVO (284±88 vs 222±96mL/kg/min; P<.001), and SVC flow (100±36 vs 86±40mL/kg/min; P<.001) compared with the ECC group. Peak systolic strain was lower (-17±3 vs -22±3%; P<.001), but there was no difference in peak tissue Doppler flow (0.06 m/s [IQR, 0.05-0.07 m/s] vs 0.06 m/s [IQR, 0.05-0.08 m/s]). UCM increased cardiac output (as measured by LVO) compared with ECC in nonvigorous newborns. Overall increases in measures of cerebral and pulmonary blood flow (as measured by SVC and RVO flow, respectively) may explain improved outcomes associated with UCM (less cardiorespiratory support at birth and fewer cases of moderate-to-severe hypoxic ischemic encephalopathy) among nonvigorous newborn infants.

Factors affecting the microbiological quality and contamination of farm bulk milk by Staphylococcus aureus in dairy farms in Asella, Ethiopia

BackgroundThe determination of the microbiological quality and safety of raw milk and the associated influencing factors at the farm level is very critical given that the quality or safety of subsequent products that are further produced depends on this. Therefore, this study aimed to determine the microbiological quality and safety of bulk milk and identify associated risk factors, and assess the presence/absence of S. aureus in bulk milk with potential contaminating sources in dairy farms in Asella, Ethiopia.ResultsThe geometric means of bacterial counts in farm bulk milk were 5.25 log cfu/ml, 3.1 log cfu/ml and 2.97 log cfu/ml for total bacterial count (TBC), coliform count (CC) and coagulase-positive staphylococci count (CPS), respectively. Of the 50 dairy farms, 66, 88, and 32% had TBC, CC and CPS counts, respectively, that exceeded the standard international limits for raw cow’s milk intended for direct human consumption. TBC tended to increase as CC increased in bulk milk (r = 0.5). In the final regression model, increased TBC, CC and the contamination of farm bulk milk by S. aureus were significantly associated with dirty barns, dirty cows and soiled udder and teats. TBC was higher during the rainy season than during the dry season. The reported practice of washing teats with warm water significantly decreased CC and CPS. The occurrence of S. aureus was significantly (p < 0.05) higher in bulk farm milk (42%) than in pooled udder milk (37.3%), teat swabs (22.5%), milkers’ hand swabs (18%), bulking bucket swabs (16.7%), milking container swabs (14%), and water for cleaning of udder and milkers’ hands (10%). The questionnaire survey result showed widespred raw milk consumption habits, low level of training and poor hygienic milking practices.ConclusionsThis study revealed low-quality bulk farm milk with high bacterial counts and a high occurrence of S. aureus. This indicates the potential food safety risks due to consumption of raw milk or its products. This study suggests awareness creation to dairy farmers and the public on hygienic milk production and heat treatment of milk before consumption.

Validation and application of an immunochromatographic test to detect four macrolides and two lincosamides in raw cow milk

In this study, an immunochromatographic test (using the Charm QUAD2® Test) was used to screen for residual macrolides and lincosamides in raw cow’s milk. The validation parameters (selectivity/specificity, detection capability (CCβ), and ruggedness) were in agreement with the requirements of[EC] 2021. The selectivity of the immunochromatographic test was verified by the negative results of microbiological tests. The false-positive rate was 0%. The CCβ values of the immunochromatographic test for various antibiotics in milk were as follows: erythromycin 0.02 mg/kg, spiramycin 0.1 mg/kg, tilmicosin 0.025 mg/kg, tylosin 0.05 mg/kg, lincomycin 0.15 mg/kg, and pirlimycin 0.15 mg/kg. The determined CCβ values were lower than the respective maximum residue limits (MRLs; regulatory limits in Japan) for milk, except for lincomycin (equal to the MRL). The presence of antibiotic groups other than macrolides and lincosamides did not interfere with the specificity of the test. It showed no significant difference in lot-to-lot repeatability. The results obtained by the two researchers showed no significant differences. Finally, the test was applied to milk samples obtained from a tylosin-treated cow. The outcome was positive and in agreement with the results of the chemical analytical and microbiological methods. Therefore, this validated immunochromatographic test is expected to be suitable for routine analysis to ensure milk safety.

Dynamics of 17β-estradiol under influence of technological operations during production of dairy products

Safety of milk can decline because of high concentrations of steroid hormones like 17β-estradiol, which is associated with the development of some oncological diseases and reproductive disorders. We studied the effects of thermal processing of raw milk and technologies of production of butter and yogurt on the concentration of 17β-estradiol. For this purpose, we determined the amount of 17β-estradiol in raw milk, after pasteurization under different regimes, boiling and during the production of butter and yogurt. Content of 17β-estradiol was determined using the method of immunoenzymatic analysis. We determined that low-temperature processing of milk at the temperature of 77.0 ± 1.0 °С for 1 min caused no changes in the structure of the estrogenic hormone 17β-estradiol, resulting in practically no changes in its amount in pasteurized milk. We determined that 17β-estradiol in milk is a temperature-stable hormone with no tendencies towards significant decrease when subject to high-temperature processing (85.0 ± 1.0 °С for 1 min) and during boiling, because the amount of the hormone decreased on average by 5%. Therefore, we may state that after pasteurization or sterilization, the concentration of 17β-estradiol in drinkable milk would not be significantly different from its initial amount in raw milk. We determined significant increase in 17β-estradiol in butter (3896.1 ± 67.5 pg/g), as compared with the concentration in raw milk (189.4 ± 12.5 pg/mL), and its insignificant content in buttermilk was insignificant (29.3 ± 1.8 pg/mL). The concentration of 17β-estradiol in milk decreased by 25% during 9-month storage at the temperature of –18 °С and by 20% at the temperature of –9 °С. This process can be applied to butter made from milk of cows at late stages of lactation, which contains high level of estrogen. We determined that the steroid hormone 17β-estradiol did not break down under the influence of dairy acid that accumulates as a result of lactic acid fermentation, both with the participation of mixed microflora of raw milk and pure lactic-acid bacteria of fermentation starter for yogurt. The prospects of the studies are the development of a safe maximum allowable level of 17β-estradiol in raw milk and methodological evaluation at a milk-processing factory.

Microbiological, Physicochemical and Nutritional Properties of Fresh Cow Milk Treated with Industrial High-Pressure Processing (HPP) during Storage.

The safety, shelf life, and quality of fresh cow milk treated using industrial High-Pressure Processing (HPP) treatment at 600 MPa for 10 min was studied to identify the novelty of this non-thermal technology in milk processing. Changes in microbiological and physicochemical properties, including nutritional values of vitamins and amino acid profiles, were measured for a 60-day storage period at 6 °C +/- 1 °C. The HPP treatment produced milk that met all microbial safety requirements and exhibited a shelf life beyond 60 days in a hot and humid region. High physicochemical stability was achieved, with consistent pH and undetectable titratable acidity. The HPP treatment successfully retained all vitamins and minerals, including calcium (99.3%), phosphorus (99.4%), and magnesium (99.1%). However, the 60-day storage caused some degradation of Vitamin A (25%), B3 (91%), B5 (35%), B6 (80%), and C (85%), and minerals, including potassium (5%) and zinc (18%) when compared with fresh milk. This research has shown that the adoption of advanced treatment with HPP is very beneficial to the dairy industry in preserving milk quality in terms of its physicochemical and nutritional properties and extending its storage shelf life beyond 60 days.

Investigating Genetic Characteristics of Chinese Holstein Cow’s Milk Somatic Cell Score by Genetic Parameter Estimation and Genome-Wide Association

The quality and safety of milk is challenged by cow mastitis, and the value of somatic cell score (SCS) in milk is closely related to the occurrence of mastitis. This study aimed to analyze the genetic characteristics of SCS across the first three parities in Chinese Holstein cattle, as well as to investigate potential candidate genes and biological processes that may play a potential role in the progress of cow mastitis. In this respect, we evaluated genetic parameters and conducted a genome-wide association study based on the test-day records of SCS for Chinese Holstein cows; we also validated key candidate genes using a quantitative reverse transcription PCR (RT-qPCR) experiment in primary bovine mammary epithelial cells (bMECs). The heritability of the SCS 305-day performance in milk varied between 0.07 and 0.24, and decreased with increasing parity. As the time interval grew larger, the genetic and permanent environmental correlations with the number of days in milk (DIM) weakened. Six significant single-nucleotide polymorphisms (SNPs) were identified in the association analysis, one of which was located within the exonic region of CD44. This exon-associated SNP may modify the activity of the protein encoded by the CD44. A total of 32 genes within the two hundred kilobase (kb) range of significant SNPs were detected, and these genes were markedly enriched in eight Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways and 22 biological processes, mainly participating in the progress of transmembrane transport, inflammatory factor regulation, cellular responses, the Toll-like receptor signaling pathway, and the MAPK signaling pathway. Nine genes, including the PKD2, KCNAB1, SLC35A4, SPP1, IBSP, CD14, CD44, MAPK10, and ABCG2 genes, were selected as candidate genes that could have critical functions in cow mastitis. These findings can serve as a foundation for molecular breeding and as valuable data for reducing the incidence of mastitis of Chinese Holstein cattle at the molecular level.

Effect of Adulterants on Quality and Safety of Cow Milk: A Review

Cow milk adulteration is the act of intentionally decreasing the quality of milk offered for sale either the admixture or substitution of substance or removing of some valuable ingredient. Milk has a high food value, since it comprised of a variety of nutrients. Scientific evidence supports, the consumption of cow’s milk and dairy products as part of a balanced diet and it is perfect and complete food. Therefore, milk and its derivatives contribute essential micro and macronutrients to the diet, when consumed according to appropriate national guidelines. However, different adulterants are added, to increase its quantity and done for financial gain. The common adulterants used in cow milk adulteration are water, starch, flour, urea, formalin, sodium hydro oxide and cane sugar. Water is the most common adulterant. These adulterants have effect on the nutritional quality of cow milk by decreasing the concentration of ingredients found and wholesomeness of the milk. To dilute milk, cheaper materials will be added. Almost all commercially available milk comes from cow and major milk adulteration occurs with cow’s milk and its products. These, adulteration of milk can pose serious risk to human health. The composition of milk varies with the breed of cow, stage of lactation; feed, season of the year. Therefore, both intentional and incidental milk adulterations affect nutritional quality and safety of milk. This review aims to review the effect of adulterants on safety and quality of cow milk. Even while financial gain is one of the main drivers of cow milk adulteration.

Therefore, the study of the influence of environmental factors on the quality of livestock.

Blockchain Based Solutions for Milk Procurement Management and Adulteration Detection

In our day-to-day life, milk is a fundamental component that is rudimentary for many food products. Consuming milk regularly is very important because it is a mixture of various macro and micronutrients and is a source of proteins, fats, carbohydrates, and vitamins. Particularly in our nation, women’s empowerment and milk production are closely related. Furthermore, rural Indian communities rely heavily on small holder dairy farms for their livelihoods, and women play an important role in milk production. The dairy sector is estimated to contribute around 6% of the country’s agricultural GDP, with the value of milk production in India exceeding 200 million ton by the year 2023 [1]. Milk is a highly perishable commodity, when not handled properly it is susceptible to microbial spoilage. The milk after production must be processed properly to retain its quality till consumption. Nowadays, many milk vendors are adulterating the milk for financial gain. Consumers have the rights to obtain good and safe milk, as it is largely consumed by people of all age groups. Supply chain process of a small holder dairy farming has been examined recently in Salem, Tamil Nadu, India and it has been observed that the current process in dairy involves the accumulated milk from dairy farmers are being poured into the milk cane, then being detected and sent to a larger container where it is mixed with all the other milk. In most cases, it would be impossible to separate fresh milk from un-fresh milk. Therefore, the objective of this research work aims to develop a Blockchain and IoT based solution for milk procurement and adulteration detection there by providing a complete milk traceability data to the consumers from production to consumption, and establishing a trust in providing quality milk to the society.

The improvement of the body and udder hygiene influence on the milk safety and composition on small dairy farms in Serbia

The hygienic condition of dairy cows and their udders in 128 small household farms in different regions of Serbia, producing mostly milk, having 5-15 cows, a milk cooler and at least one milking machine, was evaluated by the following indicators: 1. general assessment of body cleanliness, 2. visual inspection of teats and udder base, and 3. maintenance of udder cleanliness, rated on a scale of 0 and 1 or 1 to 5. The samples were taken at each visit to the farm after cooling and tested for milk protein and fat content, somatic cell count (SCC) and the total number of microorganisms (TNM). The milk fat content was determined by the Gerber method, the protein content by the Kjeldahl method, the TNM according to the ISO 4833-1:2013 method and the SCC using Fossomatic TM. The IBM SPSS program was used for statistical data processing. Capacity, housing system, breed, milking system, number of cows, and capacity occupancy mostly had a very significant or significant impact on hygiene parameters, protein and fat content, SCC and TNM in milk. The hygiene parameters showed a continuous trend of improvement in relation to the visits. TNM mean scores increased after each visit, with significant differences between visits (F=9.63, P&lt;0.0001). SCC scores varied very significantly between visits (F=5.17, P&lt;0.0001). The number of visits tended to show a significant influence on the milk fat rate (F=2.221; P?0.1), but no influence on the milk protein rate (P=0.480; F=0.901).

MILK SECTOR TRENDS: THE CASE OF ALBANIA

Since the transformation of Albania's agricultural sector in 1992, it has shifted from subsistence farming to a thriving commercial industry, making a significant 17.7% contribution to the country's GDP. Among the agricultural subsectors, animal production, particularly in the dairy sector, plays a pivotal role in both farm income and market supply, contributing about 40% to the total agricultural value. Despite this positive trajectory, the dairy production sector is confronted with a set of challenges. This paper conducts a comprehensive analysis of the dairy sector in Albania, using a systematic methodological approach that involves primary and secondary data analysis. The analysis underscores the need for substantial improvements in various aspects of primary production. These improvements should primarily focus on feed and forage practices, specialized dairy breeds, and advanced animal husbandry techniques. Attention is also required for milking and milk collection, which includes maintaining high standards of hygiene, animal health control, milk safety, quality controls, and effective cooling systems. Furthermore, the conclusions highlight the significance of strengthening public extension services, motivating agricultural advisors, and providing financial support to address the knowledge gaps among farmers. Additionally, it is crucial to emphasize that Albania currently depends on net imports for various agricultural products, including milk, as it aligns with EU standards. This underscores the need for efforts to enhance competitiveness and food quality within the dairy sector. The findings of this study are based on the information and data accessible at the time of the analysis, and thus, they may not capture the entirety of the complexities within the dairy sector in Albania. The dairy industry is subject to various external factors, such as changes in global markets, trade policies, and economic conditions, which can influence its performance. In summary, while this research provides valuable insights into the challenges and prospects of Albania's dairy sector, readers should consider these limitations to understand the potential constraints and biases in the study, as well as the dynamic nature of the industry beyond the scope of this analysis.

Evaluation of the quality and safety of cows' milk when using the mineral elements

A successful feeding program should solve the following problems: achieving planned milk production, increasing dry matter intake and improving ruminal microbiota. As an integral part of the diet, feed additives have an impact on the animal's body, which is expressed, for example, in an increase in average daily weight gain, a decrease in conversion, an improvement in metabolic metabolism and so on. However, it should be noted that feed additives alone do not guarantee of high productivity or profitability of milk production. The purpose of these studies was to evaluate the effect of the multicomponent feed additive Felucen on the sanitary quality and safety of cows' milk. The studies were conducted on the basis of training and experimental farm, where two groups of dairy cows, 40 heads each, were formed according to the principle of analogues. All cows of both groups received the basic diet accepted on the farm. Additionally, the first group received Felucen feed additive at the rate of 5 g per 1 kg of body. Analysis of the milk composition and productivity was carried out on the 10th, 30th, 60th and 90th day. The use of Felucen provided an increase in the milk productivity of cows by 11% and an increase in the quality indicators of milk: the mass fraction of fat increased by 0.11%, protein - by 0.21%, lactose - by 0.20%.

АНАЛИЗ ФАЛЬСИФИКАЦИИ И БИОБЕЗОПАСНОСТИ МОЛОКА СЫРЬЯ В АЛТЫНСАРИНСКОМ РАЙОНЕ

The article shows monitoring studies on the issue of providing dairy processing enterprises with raw materials produced by dairy farms located in the Kostanay region. The research was carried out on the materials of official statistics using analytical materials of public administration bodies. To establish the well-being of the subsidiary farms of the Altynsarinsky district, the monitoring of the reporting documentation provided by the veterinary supervision authorities was carried out. The analysis of scientific articles on the safety of raw milk was carried out, with citations from foreign and domestic literature. The article reveals the problem of shortage and falsification of raw materials in the Kostanay region. The percentage and type of falsification have been established. The analysis of the purchased raw milk from individual deliverers, according to physico-chemical and microbiological indicators, was carried out. The results of microbiological examination of raw milk samples are reflected. The percentage of bacterial contamination of the studied samples was established. Studies of raw milk on the content of somatic cells were also carried out. The article shows the analysis of the naturalness of raw milk. To do this, the following indicators were determined: dry skimmed milk residue, density, mass fraction of fat. The importance of the work of specialists of veterinary supervision and control in terms of educational activities with individual deliverers was also noted.

Islands of Milk Insecurity in World’s Leading Milk Producer: A Case of Andaman and Nicobar Islands, India

India, with the world’s largest cattle population, is a leading producer of milk, and claims to be self-sufficient for dairy production. However, such an important component for nutritional security has been reported to be adulterated by 68% by the national food safety agency. This study challenges the basic claim of self-sufficiency in terms of milk production and food security for milk and milk products. A novel model for studying milk safety is presented, which evaluates the prevailing conditions in the Andaman and Nicobar Islands (A&amp;N), India. There are no comprehensive data nor studies available for this region. The assessment of the pillars of food security found that with the present population load, there is an annual deficit of 25673.7 MT of fluid milk in the A&amp;N Islands. The study found that the average herd size is 1.9, with about 26.9% of the animals rearing desi (non-descriptive) cattle, characterized by low production levels of 3.95 L/day and with gene frequency of 16.48% for the A1 allele. None of the milk samples were found to be positive for antibiotic (tetracycline and aminoglycoside) residues. However, 4% of the milk samples were found to be positive for the aflatoxin residues above the permitted MRL. The KAP study shows that awareness regarding clean milk production, antimicrobial residues, withdrawal timings, aflatoxins, etc. is poor/highly limited among the farmers of the region. The output may act as a referral study and a template for future studies for the assessment of product-specific food security. Our findings highlight the limitations of the present approach and the need for additional data, using a wider range of research techniques for assessing dairy. Whilst not definitive, it aims to highlight those factors which are considered crucial to an understanding of contemporary milk safety controls.
