Federal officials have identified a new outbreak of hepatitis A infections suspected to be from a food source.
The Food and Drug Administration reports that it has begun product traceback efforts, but the agency has not named the product or products being traced.
As of March 1 there have been nine patients identified. The FDA has not reported where the patients live or their ages.
Hepatitis A can be transmitted when food handlers have contaminated hands. This contamination usually comes from microscopic amounts of feces. Thorough hand washing is one of the best ways to prevent transmission of the disease. Food surfaces can become contaminated as well as foods and beverages.
