If you experience gastrointestinal problems or muscle pain and swelling about a week after eating pork or wild-animal meat, talk to your doctor. People get trichinosis when they eat undercooked meat — such as pork, bear, walrus or horse — that is infected with the immature form larvae of the trichinella roundworm. In nature, animals are infected when they feed on other infected animals. Pigs and horses can become infected with trichinosis when they feed on garbage containing infected meat scraps.
Cattle don't eat meat, but some cases of trichinosis in humans have been linked to eating beef that was mixed with infected pork or ground in a grinder previously used for contaminated pork. Due to increased regulation of pork feed and products in the United States, pigs have become a less common source of infection. Wild animals, including bear, continue to be sources of infection. Except in severe cases, complications related to trichinosis are rare. In cases of heavy infestation, larvae can migrate to vital organs, causing potentially dangerous, even fatal, complications, including:.
The best defense against trichinosis is proper food preparation. Follow these tips to avoid trichinosis:. Avoid undercooked meat. Be sure to thoroughly cook cuts of meat until brown.
Cook pork and meat from wild animals to an internal temperature of F 71 C throughout. For whole cuts and ground varieties of poultry, cook to a temperature of at least F 74 C.

Trichinella is a microscopic parasite, unable to be seen with the human eye. The Centers for Disease Control and Prevention said cases of trichinosis have decreased because of legislation.
Females seek out meat scraps in garbage or the body of a dead animal to lay their eggs in the decaying tissue. The flies as well as the maggots favor warm conditions for egg laying and hatching. The entire life cycle of a blow fly typically spans days. Stages of development pass more quickly in warm weather, and cool temperatures slow development. An adult female lays eggs inside meat tissue. The maggots hatch within 48 hours after the eggs are laid.
The larvae pass through multiple stages of development, called instars. The larval stage continues for 3 to 9 days, depending on temperature. During the larval stage, the maggots consume meat as they burrow through the tissues. They need to eat enough to sustain them through the next stage of development. After the maggots have changed into the final instar stage, they leave the meat source where they hatched to form a pupa.
During the pupal stage, the larvae encases itself in a protective structure where it completes its development.
