A food service worker at Harbor Restaurant at Pier 38 who was on the job as recently as Monday has come down with hepatitis A, according to the state Health Department.

People who ate at the restaurant from Aug. 26 to Sept. 12 may want to contact their health providers about getting a protective vaccine or immune globulin, the department advised in a media release Tuesday.

“Because of the long incubation period for hepatitis A, we are continuing to see new cases of this illness even after identifying and removing contaminated scallops from Hawaii restaurants, and individuals exposed in July and August may become ill as late as September or October,” said Dr. Sarah Park, state epidemiologist.

“We want the public to understand that this does not represent a new outbreak, nor is this restaurant considered a source of the ongoing outbreak.”

The risk of contracting the disease at the restaurant, at 1133 North Nimitz Highway, is low. The vaccine or immune globulin can prevent the disease if given within two weeks of exposure.

As of last Wednesday, there were 252 confirmed cases in this hepatitis A outbreak. The department will update the case count today.

The Health Department last month identified frozen scallops packaged by De Oro Resources and served raw at Genki Sushi as the probable cause of the outbreak.

According to an order by the Philippines’ Department of Agriculture Bureau of Fisheries and Aquatic Resources, the Philippine government has suspended distribution of seafood products from De Oro.

Andres Bojos, director of the agriculture bureau in the Central Visayas region, said officials required the company to test workers, including those who shuck scallops and those who work in their plant. All of them tested negative for hepatitis A, he said.

“We required the operator to subject all their personnel involved in the supply chain from those who shuck the meat of scallops in Masbate to their people in their plant here in Cebu to medical tests, but all of them tested negative for hepatitis A,” Bojos said.

He said those who were tested include around 100 De Oro workers in its plant in central Cebu province and 29 people who work in De Oro’s pre-processing plant in Masbate in the eastern Philippines, where the company gets some of its scallops.

Bojos said a water sample from Masbate was found to have a high level of coliform bacteria, and scallops are not being acquired from that area for now. He said there is also a possibility that the scallops were contaminated during the handling of the food in Hawaii. There are no known cases in the region of hepatitis A from eating scallops, he added.

Messages left for De Oro Resources remain unanswered.
