Many times, eating habits have a great influence on the immunity of external microorganisms. For example, animals are used to eating things that have not been cleaned and heated, and microorganisms in the body have become accustomed to certain pathogenic microorganisms and can keep a balance, just like ducks.

Theoretically speaking, as long as meat is treated harmlessly, human beings can eat it. In Mexico, the eating habit of eating insects is relatively popular. Local residents will remove the head and legs of cockroaches and then fry the rest to make special food. In China, many famous medical books, such as Shen Nong's Classic of Materia Medica and Compendium of Materia Medica, all record that cockroaches are used as medicine. Chinese medicine usually grinds cockroaches into powder, which is used for promoting blood circulation, removing blood stasis, diuresis and detumescence, and also has a good effect on insect and snake bites.

However, cockroaches can be artificially infected with bacteria that cause cholera, pneumonia, diphtheria, gangrene, anthrax and tuberculosis in Asia. Cockroaches can carry many kinds of eggs, such as roundworms, hookworms, beef tapeworms, roundworms and whipworms. They can also be used as intermediate hosts for Echinococcus moniliforme, Hymenolepis brevis, tumor tubes and other nematodes.

In addition, cockroaches can also carry a variety of protozoa, four of which are pathogenic to humans or animals, such as amebic dysentery and Giardia. Experimental studies have confirmed that cockroaches can carry, preserve and excrete viruses, including Coxsackie virus and poliovirus. Cockroaches can also carry fungi. A variety of fungi, including a large number of Aspergillus flavus, were isolated from cockroaches captured indoors in Nanjing and Nantong, Jiangsu Province.

Therefore, eating cockroaches is still not recommended. If you must experience it, replace it with locusts or cicadas and earthworms. Not easy to accept.
