FREDONIA, N.Y. — People who ate at a Fredonia restaurant may have been exposed to Hepatitis A.

Chautauqua County health officials say anyone who ate at The Mustard Seed between April 1-May 19 may have been exposed.

They say most people don't get sick when an employee at a restaurant has Hepatitis A, but there is still a risk.

Symptoms include fever, loss of appetite and nausea.

The health department is advising anyone who ate food at the restaurant or takeout between May 8-19 get a free Hepatitis A vaccine.

It will be offered Saturday at a clinic at SUNY Fredonia.

Health officials say the vaccine is only effective within two weeks of exposure.
