On-Farm Food Safety Certification Trichinae Herd Certification Dr. Dave Pyburn National Trichinae Coordinator USDA, APHIS, VS
Influences on the Prevalence of Trichinella in U.S. Pigs • 1953-1962 – Enactment of garbage cooking laws aimed at CSF (hog cholera) and vesicular exanthema • Reduction of waste feeding operations • Movement of U.S. pork industry to increased biosecurity on operations
Pre-Harvest Certification • Based on production of pigs under management practices which minimize the risk of exposure of pigs to Trichinella • Uses written records and third party auditing to document on-farm good production practices • Is supported by regular testing of certified animals to verify the absence of infection and USDA oversight
Risk Exposure to meat waste containing infective larvae. Exposure to infected rodents. Exposure to infected wildlife. Cannibalism. Intervention Proper cooking of all meat containing waste. Documented rodent control program. Biosecurity to eliminate exposure to wildlife. Prompt removal of dead pigs. Interventions to Reduce or Eliminate Risk of Pig Exposure to Trichinella
Program for Certification of Trichinae Safe Production • Educational materials are distributed describing the requirements for certification. • Producer and herd veterinarian work together to implement/document good production practices which reduce risk of exposure to trichinae.
Program for Certification of Trichinae Safe Production • At the request of producer, trained and accredited veterinarian conducts an audit which is submitted to USDA. • Based on the audit: • Farm receives USDA certification and pigs may go to slaughter with a trichinae-safe designation; or • Report summarizes deficiencies which must be addressed prior to certification.
Program for Certification of Trichinae Safe Production • Certified pigs go to slaughter with trichinae-safe certificate. • Certified pigs are processed separately from non-certified pigs. • Regular testing of certified pigs is conducted with samples collected at slaughter. • Spot audits are conducted on a random sub-set of certified farms.
