3. 3 Health Risk Associated with Recreation Use of Untreated Surface Water James Howell, DVM, MPH Diplomate, ACVPM State Epidemiologist Indiana State Department of Health

4. 4 Untreated Surface Water Ponds, creeks, rivers, lakes, sea shores Unfiltered to remove protozoa parasites Untreated with chemicals to destroy bacteria or virus

6. 6 Bacteria of Concern Campylobacter E. coli 0157:H7 Leptospira Salmonella Shigella Swimmer’s ear

7. 7 Parasites Cryptosporidium parvum Naegleria Swimmer’s itch Acanthamoeba

8. 8 Toxins Cyanotoxins are a diverse group of chemical substances that are categorized by toxic effects as follows :  Neurotoxins affect the nervous system.  Hepatotoxins affect the liver.  Tumor promoters - chemicals that can increase tumor growth.

9. 9 Toxins Cynobacteria  Microcystins - liver, tumor promotor  Saxitoxins - neurotoxin  Anatoxin-a - neurotoxin  Nodularins - liver, tumor promotor  Lipopolysaccharide - inflammation  Cylindrospermopsin – liver other organs

10. 10 Cyanotoxin Human Health Effects Skin  Rashes, hives, skin blisters Inhalation  Runny eyes and/or nose, sore throat, asthma-like syndrome, allergic reactions Swallowing  Acute and severe gastroenteritis  Liver toxicity  Neurological symptoms

11. 11 Effects on Pets and Domestic Animals Drinking contaminated water may cause  Photosensitization  Liver failure  Neurological Signs and Symptoms  Lethargy, muscle tremors, rapid breathing,  Twitching, paralysis, convulsions Can cause death

12. 12 Fish from Contaminated Waters Shellfish such as fresh water mussels can bio- accumulate toxins and should not be eaten Healthy fish may be eaten, but should exclude liver and kidneys

13. 13 Bottom Line Risk of health effects is dose dependent  Higher the level of toxin present, higher the risk  Skin contact, nasal contact, ingestion The route of exposure can increase the risk of health affects.

14. 14 What a Recreational User Can Do Wise users take certain sensible precautions :  Prepare before entering the water: Bring appropriate gear. Be sure to check weather conditions  While in the water: Recreate in groups Always supervise children Try to avoid consuming large amounts of water  When you’re finished: Make sure you shower Take time to clean your equipment
