USDA Multi-Agency Project: Collaboration in Animal Health, Food Safety & Epidemiology (CAHFSE)

Despite producer interventions, on-going research and continued surveillance, food borne outbreaks continue and multiple antimicrobial resistant bacteria have emerged. A multi-agency APublic Health Action Plan to Combat Antimicrobial Resistance@ was developed to address these concerns and one USDA response was the development of the Collaboration in Animal Health, Food Safety and Epidemiology (CAHFSE), a partnership among the Agriculture Research Service (ARS), Animal and Plant Health Inspection Service (APHIS), and Food Safety Inspection Service (FSIS. The objective of CAHFSE is to implement and expand a surveillance system patterned after the APHIS National Animal Health Monitoring System (NAHMS) which focuses on animal health and food safety. Swine is the first commodity in CAHFSE. To date, fecal samples from 8 farms have been collected and processed for culture of Salmonella, Campylobacter, Enterococci and E. coli. Preliminary results indicate that all four bacteria have been recovered from a number of operations and are currently being characterized

Salmonella serotypes from 1997-2003 NARMS swine diagnostic, on-farm, and slaughter samples

The veterinary component of the National Antimicorbial Resistance Monitoring System (NARMS) identified 8527 Salmonella isolates from swine samples in the years 1997-2003. Fifty-one Salmonella serotypes were identified from 3147 diagnostic, 2138 on-farm, and 3246 slaughter samples

Antimicrobial resistance in Salmonella from 1997-2003 NARMS swine samples

A total of 3246 swine slaughter and 3147 swine diagnostic Salmonella isolates from the National Antimicrobial Resistance Monitoring System (NARMS) for the years 1997-2003 were tested for antimicrobial resistance. No resistance was detected in any Salmonella isolates for ciprofloxacin or amikacin. For all other antimicrobics tested, more resistance was observed in diagnostic isolates compared to slaughter isolates

Antimicrobial resistance in Salmonella isolates recovered from swine: A NARMS report

In 1996 the Food and Drug Administration Center for Veterinary Medicine established the National Ant1microbial Resistance Monitoring System - Enteric Bacteria (NARMS) as a post-approval monitoring program. From 1997 through 2005, 10,565 Salmonella isolates originated from swine slaughter/processing (n=3,848), diagnostic (n=4,579) and on-farm (n=2138) sources as part of the animal arm of NARMS. Relative to 2005, the top five Salmonella serotypes from slaughter/processing (in decreas1ng frequency) were S. Derby, S. Typhimunum var. 5-, S lnfantis, S Anatum, and S Johannesburg while diagnostic serotypes were S Typhimurium var 5-, S Choleraesuis var kunzendorf, S Derby, S Typhimunum, and S Heidelberg Increased antimicrobial restistance was most often observed for diagnostic versus slaughter/processing isolates although there were exceptions for some drug and serotype combinations. For all years, greater than 55% of the slaughter/processing isolates were either pan-susceptible or resistant to only one antimicrobial, which was most often tetracycline. Since 1997, approximately 41% of the isolates exhibited multi-drug resistance, defined as resistance to ~2 antimicrobials. Of the 723 S Typhimunum DT104 isolates from swme only 24% (n=176) originated from slaughter/processmg These data reaffirm that overall patterns of resistance are highly dependent on the Salmonella serotype distribution and is variable when measured at different points along the farm to fork continuum.</p

Collaboration in animal health & food safety epidemiology: swine data

The collaboration in Animal Health & Food Safety Epidemiology (CAHFSE), a partnership among APHIS, ARS, and FSIS of USDA was established to track food borne pathogens and monitor diseases from farm through plant. Sampling began in July, 2003.</p
