When looking for a surface sanitizer for your restaurant, ask the following questions: Sanitizing is also achieved through the use of chemical compounds capable of destroying disease causing bacteria. Most sanitizers must be applied to surfaces that are free of organic matter and cleaner residues. For instance, many chemical sanitizers corrode and damage food processing equipment (Fatica and Schneider, 2009; Moye et al., 2018) and could have toxic chemical residues that may harm the . Clean and sanitize food contact surfaces: after theyre used, before changing ingredients (e.g., between the prep of raw chicken and lettuce), after preparing different raw TCS foods (e.g., between the prep of melons and kale), any time youre interrupted and something may have become contaminated, and after four hours of constant use. These sanitizers function well under cold conditions (~ 4 C), thus producing acceptable microbial mortality on equipment normally held below ambient temperature. Quaternary Ammonium Compounds (QACs or Quats)
One risk management measure is the development of maximum levels (MLs) for chemical contaminants in retail foods. Chemical sanitizer concentration is expressed as. Over time, the film becomes enhanced and may contain different species of bacteria, yielding a constant source of contamination. Chemical Sanitizing Using an approved chemical solution to reduce the number of microorganisms on a clean surface to safe levels. What is the proper concentration for chemical sanitizers?
