Scientific testing by an independent laboratory has proven that a specialized laundering process offered by UniFirst Corporation to clean and maintain food industry garments can reduce bacterial contamination levels on workwear by greater than 99.9 percent. Tests indicate that the UniSafe Service for food-related businesses can return employee work garments to customers hygienically clean and virtually pathogen-free.
UniFirst’s hygienic laundering process was tested by scientists at the North American Science Association (NAMSA) of Northwood, Ohio, a microbiology consulting service and Good Manufacturing Practice independent testing laboratory with expertise in contamination controls for the medical device industry. NAMSA measured reductions of some of the most common classes of pathogens found on food industry-related work apparel, including bacteria, yeasts, and molds—all recognized as dangerous sources of cross-contamination. NAMSA’s analysis demonstrates that UniFirst’s specialized garment processing can kill virtually all organisms tested.
