Under normal circumstances, parasites are low pathogenic eukaryotes living in a parasitic way, so parasites are basically not resistant to high temperatures. The temperature of fried beef is generally above 200 degrees, so beef can kill parasites in 3-5 minutes.

Parasites adapt to the parasitic environment for a long time and lose their ability to live independently to varying degrees. The stronger the dependence of parasites on nutrition and space, the weaker their ability to live independently. The longer the parasitic life history, the stronger the adaptability and the greater the dependence. Therefore, compared with * * * habitat and mutual benefit * * *, parasites can't adapt to changes in the external environment and can only selectively parasitize on a host or a certain type.
