Some symptoms include flu-like symptoms(i.e. swollen lymph nodes, muscle aches). Severe toxoplasmosis can cause damage to the brain, particularly in newborns, as well as eye damage called ocular toxoplasmosis. Ocular toxoplasmosis is characterized by poor or blurred vision, pain when exposed to bright light and redness. •Time to onset is not established as not all persons show symptoms. •Commonly affected foods include undercooked contaminated meat (pork, lamb, venison), shellfish from contaminated waters, unpasteurized goat's milk, and foods contaminated via cross-contamination with raw meat or shellfish.

If the worm is allowed to attach to the gastrointestinal lining, symptoms include stomach pain, nausea, vomiting, abdominal distension, diarrhea (with blood and mucus) and a mild fever. Some persons also experience mild allergic reactions, like an itchy rash, and in some cases, anaphylaxis. •Time to onset depends on where the worm attaches. Gastric symptoms can develop within several hours after consumption, with small intestine or large intestine symptoms developing within several days or weeks. Severity of the symptoms depends on the number of larvae consumed and the location of the infection. •Commonly associated foods include raw or undercooked fish and squid. In particular, herring, cod, halibut, mackerel and pacific salmon (which feed on crustaceans) have been associated with anisakiasis.
