Pork meat can contain parasitic worms such as Trichinella, particularly in backyard or unregulated production systems, though commercial pork produced under strict biosecurity standards generally exhibits negligible risk.
Multiple studies demonstrate that pork meat can harbor Trichinella parasites, especially in backyard-raised pigs or regions with inadequate food safety measures. While modern commercial pork production under strict biosecurity (such as in the U.S. and Brazil) shows near-zero or negligible prevalence, the underlying biological capacity of pork to carry the parasite remains well-documented, supporting the claim.
