(See manufacturer’s recommendations for specific temperatures. While they are considered safer and less irritating, non-alcohol hand sanitizers may not be as effective against all germs compared to alcohol-based ones. Accumulation of metal fragments and food debris observed on piercing part of table mounted can opener. Best practice requires 200PPM and not above (health inspectors cite too much "quat" concentration much more that not enough). Chlorine contact time is at least 10 seconds on surfaces and 30 seconds for Quaternary ammonia. ) Quaternary ammonium compounds and COVID 19 Though QACs are in use for a long time, a significant rise in the consumption of QACs was seen during the COVID-19 pandemic. A quaternary ammonium compound solution must: Be tested at a temperature of 65°F - 75°F (18°C - 24°C) for greatest accuracy (this may not be the same as the “use” temperature. Temperature — sanitizers work best at temperatures between 55°F (13°C) and 120°F (49°C). of water in up to 500 ppm Health inspectors look for "quat" solutions to have at least 200PPM concentration of quaternary ammonium. Water temperature must be at least 180°F, but not greater than 200°F. These may vary depending on the specific sanitizer and what you are using it for. Though an advantage to most foodservice facilities, this would not be advantageous in operations producing such items as cultured dairy products, cheese, beer, etc. ) Have a concentration as specified under the FDA Food Code § 7-204.
