For instance, symptoms of a bacterial infection linked to undercooked pork yersiniosis , can appear between four to seven days after eating the contaminated food. But on average, food poisoning symptoms begin within two to six hours after consuming contaminated food.
Eating raw or undercooked pork infected with the parasitic worms, Trichinella spiralis, can lead to trichinosis. The good news is that the risks of infection are lower than they have been in the past. The USDA said its Food Safety and Inspection Service found that cooking pork to a temperature of degrees and letting it rest for three minutes is just as safe as cooking it to a higher temperature. Trichinosis Food Poisoning Trichinosis is a food-borne illness that is caused by eating raw or undercooked meats, particularly pork products infested with a particular worm.
However, fatigue, mild pain, weakness and diarrhea may linger for months or years. Your doctor may prescribe medications depending on your symptoms and the severity of infection. The symptoms of food poisoning usually begin within one to two days of eating contaminated food, although they may start at any point between a few hours and several weeks later.
The main symptoms include: feeling sick nausea. Use a meat thermometer to ensure that the meat is thoroughly cooked. Freeze pork. Freezing pork that is less than six inches thick for three weeks will kill parasites. But in the United States, trichinosis has been eliminated for all practical purposes. Trichinosis is a reportable disease.
From to , a total of ninety cases were reported—a mean annual incidence of less than one-tenth of one case per million people. Meats other than pork, including meat from bears and deer, accounted for more than half of the cases—and two were even linked to ground beef Did you know hamburgers can give you worms? Several cases were linked to wild boar and home-raised swine. Many other animals are known to harbor trichinella, including horses, walruses, and many other animals whose meat is not sold in U.
In , there was an outbreak of trichinosis in northern California caused by consumption of undercooked bear meat. The attack rate was high: of thirty-eight people attending an event where the bear meat was served, thirty became sick.
The bear in question had been shot while lying down and had appeared to be sick. So developing trichinosis from eating undercooked pork is not impossible in the United States, but the overall risk is an order of magnitude less than one in a million. And the risk is much less if you avoid eating the meat of wild animals, especially bear meat. A micromort is a unit of risk defined as a one-in-a-million chance of death; a microprobability is a one-in-a-million chance of some event.
Most people are willing to accept a one-in-a-million risk. Skiing incurs a risk of 0. In comparison, the risk of dying from eating undercooked commercial pork products in the United States is far less than one micromort, and the risk of developing trichinosis is well below one microprobability. Recommendations for cooking pork have been revised. Official guidelines no longer require us to cook all pork to degrees. Now they say it is sufficient to cook common cuts of pork to an internal temperature of degrees Fahrenheit followed by a three-minute rest after removal from the heat source during which the temperature will continue to rise for a short time.
The short answer is eating undercooked pork could make you seriously sick. But why? It all comes down to one little worm called trichinella. Trichinella is a species of worm that can commonly occur in carnivorous animals like bears or cougars, or omnivorous animals such as domestic pigs and wild boars. While you're probably not noshing on bear when you're out to a nice dinner, pork chops are a lot more common—and this is where things start to get icky.
Trichinellosis typically presents as garden-variety food poisoning, but more severe cases can result in swollen joints, conjunctivitis and more horrible stuff.
