Antimicrobial susceptibility of Salmonella isolated from various products, from 1999 to 2003.

Foodborne salmonellosis continues to be a major health concern worldwide; thus, detection and tracking of antimicrobial resistance in Salmonella isolates is of interest. The U.S.

Validation of a PCR-based method for the detection of various rendered materials in feedstuffs using a forensic DNA extraction kit.

A method trial was initiated to validate the use of a commercial DNA forensic kit to extract DNA from animal feed as part of a PCR-based method. Four different PCR primer pairs (one bovine pair, one porcine pair, one ovine primer pair, and one multispecies pair) were also evaluated. Each laboratory was required to analyze a total of 120 dairy feed samples either not fortified (control, true negative) or fortified with bovine meat and bone meal, porcine meat and bone meal (PMBM), or lamb meal.

Antimicrobial resistance of food-related Salmonella isolates, 1999-2000.

Salmonellosis is a major foodborne infection in the United States, and strains of Salmonella that are resistant to a variety of antimicrobial agents have become a major public health concern. To estimate the incidence of antimicrobial-resistant Salmonella in our food supply, the U.S.
