Still, it would be incorrect to assume that every moving or curling object is simply tissue reacting to heat. The exact explanation depends on what the material actually is.
The safest conclusion is that movement alone does not prove that something is alive, nor does it establish that the meat is contaminated.
Should You Continue Cooking the Pork Ribs?
If you discover an unfamiliar object while frying pork ribs, the safest approach is to pause the preparation.
Turn off the heat if necessary, taking care to avoid splashing hot oil. Keep the questionable meat away from other ingredients and do not taste it to determine whether it is safe.
If you have already picked up the object, wash your hands thoroughly. Clean any utensils, plates, or surfaces that may have come into contact with raw meat or its juices.
If the object appears to be a foreign material or there is a credible concern about contamination, do not serve the affected food. When you cannot confidently establish that the meat is safe, discarding it is the more cautious choice.
