How can Trichinella spiralis be eliminated from food?

1. By freezing pork

2. By cooking pork to 150°F for 15 seconds

3. By marinating pork in vinegar

4. By smoking pork at low temperatures

The correct answer is: By cooking pork to 150°F for 15 seconds

Cooking pork to an internal temperature of 150°F for at least 15 seconds is effective in eliminating Trichinella spiralis, a parasitic roundworm responsible for trichinosis. This method of cooking ensures that the meat reaches a temperature high enough to kill the parasite and any related pathogens, rendering it safe for consumption. In contrast, freezing pork is effective against certain parasites, but Trichinella can survive freezing at temperatures commonly used for home storage. Marinating pork in vinegar does not reach the necessary temperatures to kill the parasite, as marinating primarily affects flavor rather than food safety. Finally, smoking pork at low temperatures may not effectively neutralize Trichinella, as the low heat may not be sufficient to kill the parasite. Therefore, ensuring that pork is cooked properly is critical in preventing trichinosis and ensuring food safety.
