Customers may have been exposed to hepatitis A at a Costco in Montebello, health officials said Friday.

The Los Angeles County Department of Public Health said in a statement there was a “possible low risk” of exposure to the deadly virus. Butchered meat and seafood products sold at the store, 1345 N. Montebello Ave., between Oct. 22 and Oct. 31 may have been contaminated by a worker with hepatitis A.

The department said this case did not appear to be related to the current outbreak occurring among homeless populations across the state.

The current outbreak has infected more than 500 individuals and killed 21 people. In Los Angeles County, no deaths have been reported, but the virus has infected more than 20 people.

“We are actively monitoring this situation, and we don’t believe this case is related to the outbreak,” interim Los Angeles County Health Officer Jeffrey Gunzenhauser said in the statement.

Hepatitis A is a liver disease with symptoms that include fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, clay-colored bowel movements, joint pain, and a yellowing of the skin or eyes or jaundice. In extreme cases, the virus can cause liver failure and even death.

The Department of Public Health is working with Costco to investigate the possible exposure and provide employees with hepatitis A vaccines, according to the statement.

“There is no known risk of hepatitis A exposure at the Montebello Costco Wholesale now or on other dates outside the exposure period, and Public Health has not identified any new cases associated with this possible exposure,” the statement read.

The department is recommending that individuals who handled or consumed the meat and seafood products from the Montebello Costco get vaccinated or receive an immune globulin shot by Mondayto prevent or reduce illness. They should also discard any leftover meat and seafood purchased between Oct. 22 and Oct. 31.

Costco is offering free hepatitis A vaccinations at the Montebello store for any customers who may have handled or consumed the meat and seafood products that may have been contaminated.

Here are the times the vaccines are offered:

9:30 a.m. to 6 p.m. Saturday, Nov. 11

10 a.m. to 6 p.m. Sunday, Nov. 12

9:30 a.m. to 6 p.m. Monday, Nov. 13

The Department of Public Health routinely sees cases of hepatitis A. Over the past five years, there have been between 35 and 60 confirmed cases each year.
