Danger of Raccoon Feces in Swimming Pools

Raccoons can be pests and can spread germs to humans. It is important to keep raccoons out of your pool and watch for raccoon feces (poop) in and around your pool. Raccoon feces can sometimes contain the eggs of a worm called Baylisascaris procyonis, which can infect humans, particularly children, and cause severe neurologic illness.

What is Baylisascaris? 
Baylisascaris is a roundworm parasite that commonly infects raccoons. Raccoons infected with Baylisascaris can be found in all parts of the United States. When people are exposed to Baylisascaris eggs they can become ill.

What illness does Baylisascaris cause?
Baylisascaris infections in people are very rarely diagnosed. Swallowing a few Baylisascaris eggs can result in no or few symptoms. However, swallowing a large number of eggs can result in severe disease that affects the nervous system or eyes

How is Baylisascaris spread?
The parasite is spread by swallowing Baylisascaris eggs, which are found in the feces of raccoons that are infected with Baylisascaris. People can be exposed to Baylisascaris eggs in soil, water, or on objects that have been contaminated with feces from an infected raccoon.

Additional information on the disease can be found on the CDC Baylisascaris Website.

What should I do if I find raccoon feces or a dead raccoon in my pool? 
Although chlorine in pools will kill most germs that a raccoon could carry into the water, it does not kill Baylisascaris eggs.

If raccoon feces or a dead raccoon are found in the pool:

How do I clean my pool if it has been contaminated with Baylisascaris? 
Because Baylisascaris eggs are particularly tough, adding chlorine to the water will not kill them. If a lab test has confirmed that the raccoon was infected with Baylisascaris or you don’t know if the raccoon was infected because the raccoon’s feces were not tested, there are two options for cleaning your pool.

*Remember to close the pool to swimmers until you have finished cleaning the pool.

Option 1:

  • Filter the pool for a minimum of 24 hours and then backwash the pool filter.
  • Put on disposable gloves to replace the material doing the filtering (if possible). Double bag the discarded material in plastic garbage bags. Remove gloves and place them in the garbage bags. Wash your hands thoroughly with soap and water afterwards.

Option 2:

  • Backwash the pool filter.
  • Drain and hose down the pool.
  • Put on disposable gloves to replace the material doing the filtering (if possible). Double bag the discarded material in plastic garbage bags. Remove gloves and place them in the garbage bags. Wash your hands thoroughly with soap and water afterwards
  • Refill the pool.

What can I do to keep raccoons out of my swimming pool?
Raccoons usually choose certain locations to defecate (poop) and then use those same places repeatedly. Raccoons can also be attracted to areas where humans live and play. In pools, raccoons usually defecate in the shallow areas (for example, on the steps).

Here are some tips for keeping raccoons out of your pool:

  • Cover the pool area that has been visited by raccoons.
  • Keep the fence around the pool closed.
  • Find out if anyone in your area is feeding raccoons, leaving pet food outside, leaving uncovered trash outside, or using trash cans that are not properly secured. Discourage this behavior as it could be attracting animals, particularly raccoons, to your pool.
