Hepatitis A vaccine remains underused in food service workers despite decades of availability

# Editorial Summary

Hepatitis A is a viral infection that attacks the liver and spreads primarily through contaminated food and water. While most people recover fully, the infection can cause severe illness and, in rare cases, liver failure. The virus poses a particular risk in food service settings, where an infected worker can potentially expose numerous customers to the pathogen through food preparation. Despite being a preventable disease, Hepatitis A continues to appear in outbreaks linked to restaurants and food handling facilities across the country.

The good news is that a safe and effective Hepatitis A vaccine has been available since 1995, meaning we've had the tools to prevent this disease for nearly three decades. Yet vaccination rates among food service workers remain disappointingly low. This gap between available protection and actual vaccination creates an ongoing public health vulnerability. When workers lack immunity, a single case of Hepatitis A can trigger widespread illness affecting customers, staff, and the broader community.

Healthcare experts argue that universal vaccination of food service workers would be a straightforward way to prevent these preventable outbreaks. Making the vaccine standard practice in the industry, similar to other occupational health requirements, could dramatically reduce cases. The approach is cost-effective compared to the costs of outbreak investigations, medical treatment, and lost productivity.

What can consumers do? Ask your healthcare provider whether you're up to date on your Hepatitis A vaccination, especially if you work in food service, healthcare, or travel frequently. You can also support food safety by reporting suspected foodborne illness cases to your local health department, which helps identify contamination sources and protects others.
