Pseudomonas aeruginosa is the most commonly isolated bacteria in dogs with postgrooming furunculosis and is often found in human hair and skin care products, leading to possible risk for infection in consumers.1-3 This study investigated prevalence of and risk factors for P aeruginosa contamination in nonmedicated dog grooming products. Products used by grooming salons (n = 97) and pet owners (n = 20) were cultured, and potential risk factors (ie, bottle size, relative remaining volume, content dilution, expiration date, ingredient list) were recorded. P aeruginosa was identified in 14 out of 117 samples, and diluted products were contaminated significantly more often than nondiluted products. Other potential risk factors were not significantly associated with contamination. Product dilution is associated with contamination and may increase the risk for bacterial skin infection in exposed dogs.
