Chlorine test strips for food service are available to help you ensure the correct solution is created. Both should be used correctly, and maintained. Concentration is usually expressed in terms of mass per unit volume. Who should be contacted after the regulatory authority suspends the permit to operate? Sanitizing reduces the amount of bacteria or germs on a surface to safe levels. In contrast, other sanitizers have been shown to be unstable at low temperature, for instance, the QACs at high concentration (0.05%, w/v) had no virucidal effect on equine herpesvirus type 1 after 10 min reaction time at 0 C (Tsujimura et al., 2015). Chlorine Dioxide Although known as explosive in its gas form, this inorganic compound is safe in a liquid solution. Sometimes, it is thought that bacterial resistance is present when actually the organisms are avoiding contact with the sanitizing chemical because a biofilm is present. Detergent-sanitizer blends may be used if you have a two-compartment sink (used first to clean then a second time to sanitize).
