More Info

Eating undercooked or raw pork can indeed pose a risk of parasitic infections, particularly from organisms such as Trichinella spiralis, which causes trichinosis, and Taenia solium, the pork tapeworm. The risk of infection largely depends on the cooking temperature and the source of the pork. Proper cooking of pork to an internal temperature of at least 145°F (63°C) followed by a resting time of three minutes is recommended to kill any potential parasites.

In your case, if you accidentally consumed raw or undercooked salted pork, the likelihood of infection can vary. Trichinella spiralis is more commonly associated with undercooked pork, especially from wild game or poorly inspected sources. However, the prevalence of these parasites in commercially available pork has significantly decreased due to improved farming practices and regulations.
If you are experiencing any symptoms such as abdominal pain, diarrhea, nausea, vomiting, or fever, it is advisable to seek medical attention. Symptoms of trichinosis can appear within a few days to weeks after consuming contaminated meat and may include gastrointestinal symptoms followed by muscle pain, fever, and swelling of the face, particularly around the eyes. In the case of a tapeworm infection, symptoms might be less pronounced but can include abdominal discomfort, changes in appetite, and weight loss.

If you are concerned about potential infection, it is best to visit a healthcare provider. You should consider seeing a specialist in infectious diseases or a gastroenterologist, as they can provide the appropriate tests and evaluations. Diagnostic tests may include stool tests to check for the presence of eggs or larvae, blood tests to detect antibodies against the parasites, or imaging studies if there are concerns about complications.

In terms of prevention, it is crucial to ensure that all pork is cooked thoroughly and to practice good hygiene in food preparation. Avoid cross-contamination by using separate cutting boards for raw meat and other foods, and wash your hands thoroughly after handling raw meat.
In summary, while the risk of parasitic infection from consuming undercooked pork exists, the actual likelihood depends on various factors including the source of the meat and cooking practices. If you have any symptoms or concerns, do not hesitate to seek medical advice. It is always better to err on the side of caution when it comes to food safety and health.
