From the Guidelines
Individuals with hepatitis A infection should not work in the food industry until they are no longer contagious, as they pose a significant public health risk due to the potential for fecal-oral transmission of the virus. Hepatitis A is primarily transmitted through the fecal-oral route, making food handlers with active infection a significant public health risk, as noted in a study by the Advisory Committee on Immunization Practices (ACIP) 1. Key considerations for food industry workers with hepatitis A include:
- Exclusion from work until at least 1 week after the onset of jaundice or symptoms
- Exclusion from work until at least 1 week after the date the positive test result was reported if no symptoms are present
- The ability to shed the virus in their stool for up to 2 weeks before showing symptoms and for about 1 week afterward Unlike hepatitis B and C, which are transmitted through blood and body fluids, hepatitis A poses a direct contamination risk to food, highlighting the need for precautions to prevent transmission in food handling settings, as discussed in the context of vaccination and postexposure prophylaxis 1. Once recovered from hepatitis A, individuals develop immunity and can safely return to food handling duties. Local health departments typically provide guidance on when it's safe for workers to return.
From the Research
Hepatitis and Food Industry Employment
The ability to work in the food industry can be affected by certain types of hepatitis due to the risk of transmission and the potential for liver disease to impact an individual's health and ability to perform their job safely.
- Hepatitis A: This form of hepatitis is typically transmitted through the fecal-oral route, often via contaminated food or water 2. Individuals with hepatitis A can indeed work in the food industry once they have recovered, as the virus does not lead to chronic infection.
- Hepatitis B and D: Hepatitis B can become chronic and may reactivate or occur as a coinfection with hepatitis D virus 3. While vaccination against hepatitis B is available and effective, individuals with chronic hepatitis B or D may face restrictions in certain roles within the food industry due to the potential risk of transmission, although this is more related to blood and bodily fluids than food handling.
- Hepatitis C: This form of hepatitis can lead to chronic infection and is not preventable through vaccination, although new direct antiviral agents can reliably lead to a cure of chronic hepatitis C 3. Individuals with hepatitis C, especially those undergoing treatment, may need to consider the demands of their job in the food industry and how their condition and treatment might affect their ability to work safely.
- Hepatitis E: Similar to hepatitis A, hepatitis E is often transmitted through the fecal-oral route and can cause acute or, in cases of immunosuppression, chronic hepatitis 3, 2. The risk of transmission in a food handling setting would be a concern, similar to hepatitis A.
Employment Restrictions
Given the information above, the primary concern for employment in the food industry would be related to the transmission risk of hepatitis A and E, due to their fecal-oral transmission routes. However, specific employment restrictions would depend on the individual's condition, the stage of their disease, and the specific job requirements within the food industry.
- For hepatitis B, C, and D, the concern is more about the individual's health status and potential for chronic disease rather than the direct risk of transmission through food handling.
- Hepatitis A and E pose a risk due to their transmission routes, but recovery from these infections typically means the individual is no longer contagious.
It's essential to consult specific guidelines and regulations regarding employment in the food industry for individuals with hepatitis, as these can vary by location and are influenced by public health policies aimed at preventing the spread of infectious diseases 4, 5.
