Raw milk is susceptible to microbial contamination during transportation and storage. producing heat-resistant enzymes have become the most common and harmful psychrophilic microorganisms in the cold chain logistics of raw milk. To rapidly detect in raw milk, the protease gene X was selected as a detection target to construct a set of primers with strong specificity, and a loop-mediated isothermal amplification (LAMP) assay was established. The detection thresholds of the LAMP assay for pure cultured and pasteurized milk were 2.57 × 10 and 3 × 10 CFU/mL, respectively. It had the advantages over conventional method of low detection threshold, strong specificity, rapid detection, and simple operation. This LAMP assay can be used for online monitoring and on-site detection of in raw milk to guarantee the quality and safety of dairy products.

Fermented foods, particularly fermented dairy products, offer significant health benefits but also present serious concerns. Probiotic bacteria, such as lactic acid bacteria (LAB), found in these foods have been strongly linked to the selection and dissemination of antibiotic resistance genes (ARGs). This study aims to examine the potential risks associated with fermented foods, despite their importance in human nutrition, by analyzing the entire production chain from raw material acquisition to storage.

With improving living standards, functional and healthy foods are accounting for an increased share in human food. The development of dairy products that are rich in virgin omega-3 polyunsaturated fatty acids (n-3 PUFAs) has become a topic of interest. Virgin n-3 PUFA milk can provide high-quality protein and calcium, as well as provide n-3 PUFAs to improve human health.

Farms that engage in agritourism and provide niche products such as raw milk directly to consumers may request a biosecurity plan from the animal health advisors. Veterinarians who have relationships with these operations should be familiar with the state and federal requirements and pathogens of interest that may be present in raw milk and products processed from raw milk. Biosecurity plans involve an understanding of risk and specific farm goals.

Current manual multi-methods for analysis of pesticides are limited due to their complexity and scope of pesticides, high demand for time and solvent or unsuitability for broad types of food of animal origin. The following research presents a novel automated sample preparation and purification method for various food matrices of animal origin, including milk, raw milk, dairy products, cheese, eggs, fish, fish products, and offal. The Ultra-Turrax® Tube Drive System enables quick fat extraction using a solvent mixture of cyclohexane/ethyl acetate/acetonitrile.
