Swimmer’s itch has been reported at Long Lake Park in Lacey

The city of Lacey has posted a warning at Long Lake Park regarding the possible presence of a parasite in the water that causes swimmer’s itch.

Lacey officials said there have been two reported cases of swimmer’s itch associated with swimming in Long Lake, according to a social media post.

The parasite, which is associated with the presence of waterfowl and snails, can leave a red, itchy rash on the body where the person was exposed in infested water. The parasite does not have long-term effects for those who come into contact with it, according to the city.

The Thurston County Environmental Health Water Quality division does not test for swimmer’s itch, but does test for bacterial water quality. The Facebook post said recent test results have fallen within acceptable levels.

To avoid swimmer’s itch, swimmers should dry off immediately after exiting the lake and avoid feeding animals associated with the parasite, such as geese and ducks. People also should avoid swimming in marshy areas of the water.
