Whether you are enjoying some home-made goulash soup, fresh stuffed pasta from a farm shop, a grilled sausage from a kiosk or sandwiches from a petrol station, when you buy food, you want to be sure that it's not only good quality but also meets hygiene standards. To ensure that this is the case, companies that handle food in any way must work in accordance with the HACCP ("Hazard Analysis Critical Control Points") guidelines.
These regulations cover areas from thorough cleaning to safe disinfection in order to make sure that the basic food hygiene requirements are met. In these environments, it is particularly important to consider which cleaning agents are used. This is because the cleaning agents must not only effectively remove dirt and be gentle on the surfaces, they must also not be harmful to health as they will come into contact with surfaces on which food is processed.
When it comes to disinfection, understanding factors like protein interference, chemical incompatibility, and temperature inhibition is important:
Protein Interference: Chemical disinfectants lose potency when organic soils or protein residues remain on a surface. This happens because disinfectants react with food proteins rather than targeting microorganisms. To prevent this, always thoroughly clean surfaces with alternating alkaline and acidic detergents before applying sanitizer.
Soap/Surfactant Incompatibility: Residual surfactants from detergents can neutralize quaternary ammonium or chlorine-based disinfectants upon contact. Always rinse surfaces thoroughly with clean water prior to sanitizing.
Temperature Inhibition: Disinfecting solutions mixed with excessively cold water react too slowly, drastically reducing chemical efficacy and requiring far longer dwell times. Always follow label directions for optimal water temperature during chemical dilution.
