Virginia Beach has issued a swimming advisory for First Landing State Park on Wednesday until further notice.

Testing reveals that bacteria results exceed safe swimming levels. The VDH says the beach was resampled and new results are expected Thursday.

Recreational waters are monitored weekly for bacteria using indicator organisms such as enterococcus, the indicator of choice in estuarine and marine waters. Enterococci are a group of organisms used to determine the extent of the fecal contamination of recreational waters. While they do not cause illness, scientific studies indicate that their presence is closely correlated to the presence of other disease-causing organisms. People swimming or playing in waters with bacteria levels higher than the standard have an increased risk of developing gastrointestinal illness, as well as skin, eye and respiratory infections.

It is impossible to pinpoint exactly what causes each case of high bacteria levels, however, waste from wildlife, domestic pets, storm and agricultural runoff, breaks in wastewater pipes and boat discharge can all contribute to higher levels. Heavy rain often contributes to higher bacteria levels as well.
