A total of 34 people were recently sickened after oysters exposed to sewage overflow in a Potomac River tributary in Maryland in late October were then served at various locations in Loudoun and the surrounding area, a Loudoun County Health Department official told the Times-Mirror.

All of those affected have since recovered.

The oysters that cause the illnesses were found to have been served by Nomini Bay Oyster Ranch LLC, which serves oysters at various locations.

George Khan, environmental health manager at the Loudoun County Health Department, said individuals that reported ill from the outbreak have since recovered.

The majority of individuals impacted were non-Loudoun residents, according to local health officials. Only two individuals reported going to a healthcare provider for treatment.

Kevin Embrey, district epidemiologist in Loudoun, said the department became aware of the outbreak on Nov. 10, four days after the onset for the first case.

Local health officials were notified on Nov. 11 of multiple gastrointestinal illness cases related to the temporary food establishment licensed in Loudoun County and operating at several breweries and wineries including Dirt Farm Brewery, Vanish Farmwoods Brewery in Loudoun and Barrel Oak Winery in Fauquier.

Following a Nov. 6 “One My Meal Detective” complaint being submitted by a group who had purchased food from Nomini Bay Oyster Ranch LLC at Dirt Farm Brewery, health officials said several members of the group reported gastrointestinal illness beginning on Nov. 11.

Officials also identified a number of additional customers with the illness at the additional locations.

The Virginia Department of Health Office (VDH) of Environmental Health Services Division of Shellfish Safety and Water Borne Hazards team has been notified as well as counterparts at the Maryland Health Department and the VDH Office of Epidemiology Foodborne Disease Epidemiology Program, according to health officials.

The Baltimore Sun reported more than 10,000 oysters were sold around the week of the sewage overflow.

What is the name of the tributary?


I am not worried about the oysters but I am worried about the overflow not being reported and contained.
