Features: Re-Evaluating Additives on the GRAS List
Are there food additives once considered safe that should now be banned?
Features: Specialized Materials Analysis Training
Specialized materials analysis training programs can meet the requirements for possible forthcoming FDA training mandates
Departments: Future of Produce Testing in Question
The expense of detective work and exemptions for smaller farms might be a hindrance despite the availability of better and faster assays.
Departments: Identity That Goes with the Grain
Systems that track certain varieties start with certified seed and end with traceable, high-quailty ingredients
Departments: Analyze Organophosphorus Pesticides in the Apple Matrix by GC/MS/FPD Using an Agilent J&W DB-35ms Ultra Inert GC Column
Organophosphorus pesticides (OP) are widely used in the agricultural industry for crop protection. Human toxicities for this class of molecules have shown acute and chronic effects from pesticide poisoning. OP pesticides affect the nervous system of insects and mammals by inhibiting an enzyme, acetylcholinesterase, that is important in helping regulate nerve impulses.
Features: Outbreaks Spur Rapid STEC Tests
First implicated in a 1993 U.S. outbreak caused by undercooked ground beef, the Shiga toxin-producing E. coli (STEC) known as O157:H7 has become a familiar term associated with foodborne illness.
Departments: Move Over, Salmonella
You’re not likely to see a picture of Campylobacter in a post office lobby, but as of July 2011, the FSIS has introduced a new performance standard to reduce the prevalence of Campylobacter, similar to the one used for Salmonella for years.
At least one person has died and more than 110 in 31 states have been sickened as a result of this summer’s outbreak of Salmonellainvolving two distinct but closely related strains.
Microbiologic testing for specific pathogens in the U.S. food processing industry has increased 18% annually for the past three years and is expected to continue to rise, according to a recent report. U.S. food processors performed 213.2 million microbiology tests in 2010, of which approximately 22% were specific pathogen tests, according to the author of the report.
Departments: On the Trail of Salmonella
Of all foodborne pathogens, Salmonella is one of the most difficult to isolate because of its homogeneity. Strains like Salmonella enteritidis and Salmonella Montevideo are, genetically speaking, almost indistinguishable from one another using conventional tools of forensic microbiology.
