Warning On Bacteria In Water: County Health Department

From Anne Arundel Department of Health: Natural bodies of water can contain bacteria, viruses and other microorganisms. Swimmer’s ear, an infection of the outer ear, is most common, but other water-related illnesses can be acquired. Disease-causing microorganisms, such as various forms of Vibrio, can enter the body through open cuts and sores. Eating raw shellfish can also cause Vibrio-related illnesses. Each summer as water use and temperatures rise, cases of Vibrio-related illnesses are reported in Anne Arundel County.

People with liver disease or weakened immune systems are at highest risk of serious infection from Vibrio bacteria. They should avoid contact with raw shellfish whether in the water or on the plate. Although rare, Vibrio can also cause serious infections in healthy people.

The Department of Health offers the following recommendations:

• Cook crabs, oysters, clams, mussels and other shellfish completely.
• Do not swim in natural bodies of water if you have an ear infection, perforated eardrum, open cut, skin lesion or immunity problem.
• Wash well with soap and warm water after coming in contact with natural bodies of water.
• Thoroughly clean any cuts or wounds you sustain during water activities. Boaters may want to carry hand sanitizers and first aid supplies in case of cuts and scrapes, especially those related to handling seafood.
• If an infection develops in a wound, seek medical attention as soon as possible.
