Globally, disinfectants are regulated by different bodies for different applications. Disinfectant products, including disinfectants that are used in the food industry in South Africa, are regulated by the National Regulator for Compulsory Specifications (NRCS). There are various types of disinfectant products approved for use on fruit and vegetables all over the world, including Bleach (sodium hypochlorite), chlorine dioxide (CIOS), peracetic acid (PAA), organic acids, etc.

One of the most widely used disinfectants is a blend of peracetic acid/hydrogen peroxide (PAA/HP). This chemical combination is referred to as a PAA product. In addition to its use as a disinfectant agent for treating fruit and vegetables, PAA has also been used for direct applications on other types of food, including poultry, red meat, seafood, nuts etc.
