Here’s a foodborne illness that may not be on your radar. Hepatitis A is an infection of the liver caused by the Hepatitis A virus. Hepatitis A can range from a mild illness lasting a few weeks to a severe illness lasting several months. Fortunately, infection with the Hepatitis A virus is not a lifelong infection like other forms of hepatitis, and there is a vaccine to prevent it. Also, new cases are less than 3,000 a year in the United States. Hepatitis A can spread when a person ingests food or water contaminated by human waste that contains the virus. Food can become contaminated at any point: growing, harvesting, processing, handling and even after cooking. The Hepatitis A virus is even hardy enough to survive in frozen foods. Many people get Hepatitis A while traveling to other countries. Regardless of where travelers eat or stay – even at high-end resorts – it is still possible to get infected with the hepatitis A virus. Before traveling, it is important to check to see what vaccines are recommend, including the Hepatitis A vaccine.
