Try not to choose the digestive tract and intestines of animals, because most parasites are parasitic in the digestive tract. If you don't feed the digestive tract, at least 80% of the parasite problem can be avoided. In fact, the parasite problem is very easy to solve. Freezing for 3~4 days+deworming cats every month can solve most parasitic problems.
Microbial problems are more common. The random inspection of Utrecht University (citation 1) showed that Escherichia coli was isolated from 28 of 35 samples, Listeria was isolated from 19 products and Salmonella was isolated from 7 products.
Although cats' digestive system can cope with microorganisms better than humans. Also try to avoid cross-infection and bacterial reproduction.
