Researchers developed a quantitative microbiological risk assessment (QMRA) framework that evaluates the public health, environmental, and economic trade-offs of microbiological sampling plans. They suggested microbiological sampling may be most useful when risk-based or as a verification tool.

Garlic carries a distinct bacterial signature reflective of the soil in which it was grown, enabling geographic identification based on microbial composition. A novel method using microbiome data and AI analysis potentially offers a low-cost authentication technique.

Controls based on overly sensitive detection methods and focused on single outcomes may introduce unintended environmental and economic consequences. The researchers advocate for the holistic evaluation of food safety and sustainability risks within a “One Health” framework.

A national study led by the UK Food Standards Agency (FSA) found concerning increases in antimicrobial resistance (AMR) among poultry-associated Campylobacter isolates. Source attribution modeling predicted that chicken meat is by far the most dominant source of human campylobacteriosis cases.

The low-cost approach enables simultaneous detection of multiple foodborne pathogens and spoilage microorganisms in a shorter timeframe than traditional detection methods, without requiring advanced technical training. 

According to the researchers, the findings indicate that Salmonella persistence in food processing environments should not be attributed solely to disinfectant resistance. Proper implementation of cleaning and sanitization protocols alongside stringent hygiene practices remains critical.

The Achyut Adhikari Research Group is conducting several projects focused on preventive, FSMA-aligned strategies to reduce microbiological risks during pre-harvest and processing of produce, including hydroponic production, manure fertilizer treatment, food-contact surface sanitation, and antimicrobial packaging development.

The platform uses a DNAzyme-crosslinked hydrogel that produces a visible color change when E. coli is present, enabling equipment-free, point-of-use detection. It successfully detected E. coli in a range of foods, even when other pathogens were present.

Researchers have developed and validated a rapidly vaporizing antimicrobial liquid designed for dry sanitization, which, after further optimization and regulatory approvals, could offer a potential alternative to highly flammable alcohol-based solutions.

Elevated levels of certain metals and the presence of commonly used disinfectants were found to inactivate Salmonella vaccines administered to poultry via drinking water.
