Summary: Bovine viral diarrhea virus (BVDV) causes significant economic losses in the global cattle industry. Monitoring a dairy cattle herd in the eastern region of Saudi Arabia from 2020 to 2022 showed BVDV seroprevalence rates and an estimated incidence rate, providing insights into the transmissibility of BVDV.

Summary: This study investigated the variation in the prevalence and concentration of Campylobacter spp. in cows' milk, feces, and the farm environment over one year at a small German dairy farm. The highest prevalence of Campylobacter spp. was found in feces (77.1%), while it was completely absent in milking equipment and low in raw milk (0.4%). The study highlights the persistence of Campylobacter spp. in individual cows' intestines and the farm environment for at least one year, as well as the possibility of fecal cross-contamination of teats even when raw milk contamination is rare.

Summary: This exploratory study aimed to investigate the association between herd-level udder hygiene and clinical mastitis, as well as the impact of sample size and milking stage on the accuracy of herd udder hygiene assessments. The study found a positive correlation between poor herd udder hygiene and clinical mastitis, and suggested that at least 80 cows need to be scored for precise estimations. Additionally, cows scored later during milking were slightly more likely to have poor udder hygiene.

Summary: In the food sector, the dairy industry is an important economic activity that faces challenges in meeting consumer demand for natural and high quality products. To address these challenges, the application of innovative technologies, such as nanotechnology, can improve the quality and safety of dairy products. This review provides examples and promising results of using nanotechnology in dairy product preservation, including the use of nanoparticles and nanofilms. Despite the high cost and scale-up difficulties, these technologies have generated interest in the dairy industry.

Summary: The study conducted a comprehensive evaluation of Neospora, Toxoplasma, and Brucella infections in milk samples from dairy farms in Hamedan province, Iran for the first time. Results showed that milk quality was affected by infections. Control measures such as regulating animal age, herd size, and animal species, as well as health education and milk pasteurization, can help reduce the spread of infectious diseases.

Summary: This study estimated the apparent herd prevalence of Mycoplasma bovis in Irish dairy herds using bulk milk surveillance samples. The results showed a high apparent herd prevalence of seropositivity to M. bovis in Irish dairy herds. The study also identified risk factors associated with positive herd status, indicating the endemic nature of M. bovis infection in the Irish dairy sector.

Summary: This study examined anticipated COVID-safe behavior before, during, and after a youth mass gathering event. The results showed that participants anticipated maintaining appropriate physical distance from strangers, but not from friends. Both groups experienced reductions in physical distancing from friends, physical distancing from strangers, and additional protective behaviors throughout the mass gathering, and these reductions persisted at follow-up.

Summary: This prospective cohort study conducted at a public university in California aimed to identify incident SARS-CoV-2 infections and inform effective mitigation strategies. The study found that 2.6% of students and 0.4% of employees tested positive for SARS-CoV-2 infection via PCR testing. Phylogenetic analysis revealed that a super-spreader event in a student dormitory accounted for most of the infections, but there was no spread beyond the campus.

Summary: Mineral contents in thirty commercial delactosed dairy products were determined, and significant differences among different product types were observed. Mozzarella samples had higher Fe, V, and Co contents and lower Al content. The analyzed dairy samples were a good source of calcium and posed no safety risk from toxic element exposures.

Summary: This observational study aimed to assess the relationship between the prevalence of hyperketolactia (HPH) at the herd level and management practices during the transition period and herd milk production. It found that HPH in early lactation in Canadian dairy herds was associated with certain transition-period management practices and was negatively associated with herd productivity.

Summary: Milk is a valuable food for balanced nutrition in Sub-Saharan African countries. Traditional dairy value chains play a significant role in Zambia's milk supply, with differences observed between provinces in terms of cattle breeds, milk production, transport methods, and hygiene practices. The study found that unrefrigerated transport of milk by farmers can lead to microbial contamination, highlighting the need for improved food safety knowledge along the Zambian dairy value chain.

Summary: Recent evidence suggests the circulation of multiple MAP strains and mixed infections within cow herds, which calls for a rethink of MAP epidemiology knowledge. Strain typing has opened new avenues for investigating MAP transmission. The study showed that infection chains and spreading patterns could be quantified by linking genomic data with field data in a well-managed dairy herd.

Summary: In this study, it was found that pegbovigrastim treatment reduces the occurrence of clinical mastitis in dairy cows, particularly in those at higher risk of elevated lipid mobilization. However, the treatment did not have an impact on retained placenta or metritis occurrence. Additionally, cows treated with pegbovigrastim for metritis showed improved uterine healing process compared to control cows.

Summary: This study found that the impact of PEG treatment on fertility and culling interacts with pre-NEFA levels. In high pre-NEFA cows, PEG treatment increased the rate of first insemination, countered the negative effects of early-lactation CM and UD on pregnancy rates, and decreased the hazard of culling.

Summary: This study used machine learning algorithms to predict disease endpoints in untagged Salmonella genome sequences isolated from ground chicken. A semi-supervised random forest model showed the highest overall accuracy and could be used as features in future predictive modeling endeavors. The approach could be useful in various areas of food safety.

Summary: Machine learning models were used to predict the food source of clinical Listeria monocytogenes isolates, with the logit boost algorithm performing the best. The model identified dairy, fruits, leafy greens as the main sources of human clinical cases of L. monocytogenes, and provided predictive genetic features for specific sources.

Summary: This randomized controlled trial examined the effects of pegbovigrastim (PEG) treatment on the partial net return of grazing dairy cows. The study found that PEG treatment increased the partial net return and resulted in an economic benefit of $210 ± $100 per cow per year. It also reduced the cost of treatment for clinical mastitis and numerically reduced the cost of culling.

Summary: The objective of this observational study was to investigate the relationship between clinical mastitis (CM) occurring in the first 100 days of a dairy cow's first lactation and her total productive lifetime. Data were collected from 24,831 cows in 5 New York Holstein herds. Two analytical approaches were compared: separate survival analyses treating removals (death, sale) as competing events, and traditional survival analysis using Cox proportional hazards models. The findings showed that certain pathogens were associated with either higher hazard rates of death or sale. The study highlights the importance of optimizing management strategies for cows with specific types of CM early in their productive lifetime.

Summary: Climate change is dramatically changing the way humans live, with the food ecosphere being one of the most impacted areas. Climate-induced changes in temperature, precipitation, and extreme weather events are affecting the yield, quality, and safety of food. This urges the need for advanced methods, such as Artificial Intelligence, to predict future climate change-induced food safety risks from a holistic perspective.

Summary: This study investigates the awareness of Indonesian smallholder dairy farmers regarding milk quality parameters and identifies factors associated with total plate count (TPC) and somatic cell count (SCC) awareness. The study finds that most farmers have conceptual awareness of quality parameters but lack knowledge of their values. Factors such as cooperative membership, distance to other farmers, and information sources significantly influence farmers' awareness. Cooperatives play a crucial role in increasing smallholder farmers' awareness of milk quality parameters.
