<strong>Trichinella spiralis:</strong> If a human or animal eats meat infected with Trichinella cysts, the Centers for Disease Control and Prevention says, their stomach acid dissolves the hard covering of the cysts. The worms pass into the small intestine, where they lay eggs that develop into immature worms, which travel through the arteries and into the muscles. There, they curl up and return to the original cyst formation, and the life cycle continues. Symptoms can include nausea, diarrhea, vomiting, headaches, fevers, chills, cough, facial swelling, aching joints and muscle pain.
