Despite routine water testing and disinfection, pools and hot-tubs may still contain a bacteria, Psuedomonas aeruginosa, that causes a hot tub rash. This bacteria can live in temperatures up to 106°F and is resistant to chlorine and other disinfectants. 

Hot tub rashes include itchy spots on the skin that become a bumpy red rash. Pus-filled blisters can also occur. This rash usually occurs within a few days of being in the hot tub. Most rashes clear up in a few days without medical treatment, but consult your doctor if the rash lasts longer than a few days. 
Keep your friends and family safe by routinely testing for Psuedomonas aeruginosa. 

Mesa County Health Department’s Regional Laboratory can test your hot tub water. For information regarding this service, click here. Or, call 970-248-6999.
