Salmonella enterica serotype Enteritidis: increasing incidence of domestically acquired infections.

Background: Salmonella enterica causes an estimated 1 million cases of domestically acquired foodborne illness in humans annually in the United States; Enteritidis (SE) is the most common serotype. Public health authorities, regulatory agencies, food producers, and food processors need accurate information about rates and changes in SE infection to implement and evaluate evidence-based control policies and practices.

Methods: We analyzed the incidence of human SE infection during 1996-2009 in the Foodborne Diseases Active Surveillance Network (FoodNet), an active, population-based surveillance system for laboratory-confirmed infections.

Multidrug-resistant nontyphoidal Salmonella in New York state's foodborne diseases active surveillance network counties.

With the emergence of multidrug-resistant nontyphoidal (NT) Salmonella, knowledge of resistance patterns is critical for appropriate presumptive treatment. This report describes the prevalence and trends of NT Salmonella antimicrobial susceptibility within the New York State (NYS) Foodborne Diseases Active Surveillance Network (FoodNet). The NYS Department of Health, Wadsworth Center Public Health Laboratory tested all Salmonella isolates from the NYS FoodNet catchment area between May 2003 and December 2007 for antimicrobial susceptibility to ampicillin, chloramphenicol, streptomycin, sulfisoxazole, tetracycline, nalidixic acid, and ciprofloxacin.
