Trichinae is nearly non-existent in the U.S. pork supply because of increased knowledge of risk factors, adoption of controlled management practices and thorough biosecurity protocols, but many U.S. trading partners still have concerns over trichinae because of its prevalence in their domestic swine herds, which can result in severe human health issues.
Dr. Ray Gamble, past president of the International Commission on Trichinellosis, has estimated the prevalence of trichinae in the U.S. commercial swine herd at 1-in-300 million, and the Center for Disease Control and Prevention recognizes the U.S. commercial herd as low risk.
The guidance approved by the Codex commission allows countries to establish a negligible risk “compartment,” which must include controlled management conditions for swine herds, ongoing verification of the status of the compartment and a response plan for deviations from negligible risk status. Two years of data collection verifying negligible risk levels through slaughter surveillance, which consists of random sampling, is required to establish a compartment. Once established, a compartment can be monitored through on-farm audits, surveillance at slaughter or a combination of both.
The U.S. pork industry’s Pork Quality Assurance (PQA) Plus and the U.S. Department of Agriculture’s Trichinae Herd Certification programs will be used to create a compartment in the United States, the world’s largest exporter of pork.
