However, there have been several reports of outbreaks and illnesses from Hepatitis A in many states. Each year, an estimated one hundred persons die as a result of severe liver failure in the United States due to Hepatitis A. Hepatitis A is totally preventable; therefore cases, and especially outbreaks centered towards food consumption, should not occur. The Hepatitis A virus or HAV is heat stable and will survive for up to a month at ambient temperatures in the environment.

Such outbreaks are usually associated with contamination of food during preparation by an HAV-infected food handle. Although ingestion of contaminated food is the most common means of spread for Hepatitis A, it may also commonly be spread by household contact among families or roommates, sexual contact, by the ingestion of contaminated water, by the ingestion of raw or underco...
