Food processing requires the use of many industrial chemicals which when used and stored properly pose little risk. However, if industrial chemicals such as cleaners, sanitisers, pesticides, and lubricants are used or stored improperly, they may contaminate food products. Therefore processors should only use food-grade chemicals to ensure the highest purity and minimise the dangers associated with inadvertent exposure to the product. Processors should store hazardous chemicals in a locked storage space with access by authorised personnel only and processors should not leave hazardous chemicals such as cleaning or sanitising agents in the processing area.
