The USDA and other experts say the New World screwworm, a parasite that can damage livestock tissues, poses a threat to animals but does not contaminate food products. Coverage notes that the screwworm has been found in multiple locations across the United States, including Texas cattle, raising concern among producers. However, officials emphasize that the parasite does not get into meat, milk, or produce. Instead, the main risk is to animals themselves, particularly through infestations that can spread when flies lay eggs on wounds.
While the USDA assigns a risk level related to livestock exposure and monitoring, the guidance presented by outlets focuses on reassurance for consumers: the current information does not indicate that screwworms create a food safety hazard through contamination of edible products. The reporting also points to the broader role of surveillance and veterinary response to prevent outbreaks and manage cases in affected regions. Overall, sources converge on the view that the screwworm is an animal health issue, not a human food contamination issue.
