Customers who consumed food prepared at a North Merrick deli last month may have been exposed to hepatitis A, Nassau County health officials said Friday.

Anyone who visited Park Delicatessen at 1420 Park Avenue between Aug. 2 and 5, Aug. 9 and 11, and Aug. 16 and 18, and on Aug. 20 should watch for symptoms of the disease and should visit a doctor if they are experiencing symptoms of illness, the Department of Health said in a release.

Symptoms may range from mild to severe and include an abrupt onset of fever, fatigue, poor appetite, nausea, stomach pain, dark-colored urine and jaundice, a yellowing of the skin and whites of the eyes.

Officials issued the warning after confirming a case of hepatitis A virus in a food handler who worked at the deli.

The disease is rarely fatal and most people recover in a few weeks without any complications, officials said.

The symptoms commonly appear within 28 days of exposure. There are no special medicines or antibiotics that can be used to treat a person once symptoms appear. Generally, bed rest is all that is needed. Thorough hand-washing after bathroom use, and before, during and after food preparation is the most important means to prevent the spread of the illness. Sharing of food and utensils should be discouraged especially whenever anyone is ill.

The deli’s management could not be reached Friday night for comment.

For additional information on the potential exposure, call the Nassau County Department of Health at 516-227-9639 between 9 a.m. and 4 p.m. Additional information on hepatitis A is available on the state Department of Health website.
