These issues occur in international export and import of raw food materials and food, provision of regional and municipal control in food supply and sales and teaching food culture to the public.

However, angiotensin-converting enzyme is an essential receptor that causes COVID-19. After infecting any individual, COVID-19 develops in specific pattern with the following stages: replication stage and adaptive immunity stage. After adaptive immunity stage, the clinical symptoms of patient include cough, fever, runny nose, shortness of breath and many more.
