Departments: Market Expanding for Diagnostic Testing
The FDA’s growing focus on preventing food-borne illness rather than just responding after an outbreak has occurred is prompting big demand and growth in the diagnostic testing market
Electronic “tongues” or e-tongues have been the focus of research for several years, with applications for sampling wine, screening for bacteria and contamination in production, distinguishing between different varieties of beer, or evaluating milk and dairy products.

Whitepaper: Understanding, Monitoring and Meeting the Differing Global Maximum Residue Limits for Pesticides in Food and Feed Products
The purpose of this white paper is to provide an overview on current thinking within the food industry for how best to manage pesticide residue risk in food products and supply chains.
Could that omnipresent tool of high school chemistry labs—litmus paper, which indicates if a liquid solution is acidic or basic—be harnessed as perhaps the simplest assay yet for foodborne pathogens? Researchers were able to correlate levels of E. coli bacteria with pH values represented by the changing color of the litmus paper.
Features: Salmonella Control in Poultry
