Foodborne parasites are a hidden danger in our food supply. These microscopic organisms—including tapeworms, roundworms, and protozoa—can cause serious illness, sometimes with just a single contaminated bite. While many people consume at-risk foods without concern, understanding where these parasites lurk and how to safely handle food is crucial for protecting your health.
