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.

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.

Ready-to-eat (RTE) foods come with heightened food safety risks due to their lack of a final kill-step, leaving them susceptible to foodborne pathogens like Listeria monocytogenes. To help food firms control RTE food safety risks at all steps of the supply chain, this eBook provides solutions related to plant sanitation and hygiene, temperature abuse, culture, and more.

The engineering-led assessment program helps food and beverage processors identify drainage risks, prioritize hygienic upgrades, and implement facility-specific standard operating procedures (SOPs) for long-term performance.

Researchers found that the presence of nanoplastic particles can increase the expression of virulence and antimicrobial resistance (AMR) genes in Salmonella, and can also encourage biofilm formation.

In an analysis of domestic refrigerator swabs, researchers discovered complex microbial communities harboring foodborne pathogens and antimicrobial resistance (AMR). The findings also suggested that regular cleaning is possibly more important than temperature control in managing these communities.

The researchers conducted environmental sampling throughout a controlled environment agriculture (CEA) operation and tested swabs for L. monocytogenes. Boot covers proved to be a useful tool for evaluating the effectiveness of cleaning and sanitation.  

Drawing on extensive research, industry conversations, and insights from focus groups and job task analysis, the Sanitation Controls Practitioner Program (SCPP) identifies critical job tasks related to sanitation. This article, inspired by the SCPP's comprehensive approach, will delve into the three pillars of an effective sanitation program: cleaning, monitoring and verification, and sanitizing.

Applying wet sanitation in dry environments often increases risk. Food processors need a balanced understanding of these risks and their desired cleaning outcomes; specifically, the impact of different sanitation practices and how those impacts are driven by hygienic design challenges in their facilities.

3-A Sanitary Standards Inc. has published new editions of its standard for farm milk cooling and holding tanks, and its foundational hygienic equipment design standard.
