5 to 10 minutes. As arkshells are grown on the soft muddy or sandy seabed of shallow sea, some toxins or disease-causing bacteria will be accumulated in the body of arkshells, therefore, it is best to cook the arkshells for consumption to avoid the entry of diseases through the mouth. The simple treatment or no treatment of arkshells in boiling water or eating them raw can't effectively kill hepatitis A and other viruses, and the risk of food safety is still high.
Hepatitis A epidemics are triggered by people eating unclean arkshells, which in this case is a vector (biological transmission). Infection is closely related to living conditions, hygiene habits and education; contaminated water and food can also cause outbreaks, for example, the 1988 Shanghai Hepatitis A pandemic was caused by the consumption of HAV-contaminated arkshells.
