Which practice helps prevent chemical contamination of food?

Following manufacturer directions for chemicals is essential in preventing chemical contamination of food. This practice ensures that chemicals are used safely and effectively according to specific guidelines provided by the manufacturer, which typically include correct dilution rates, application methods, and safety precautions. Adhering to these instructions reduces the risk of chemical residues that could inadvertently contaminate food items.

In contrast, the other practices listed significantly increase the risk of contamination. Storing chemicals on food prep tables can lead to spills or accidental contact with food. Splashing chemicals around food is hazardous, as it can introduce chemical agents directly onto food surfaces. Using unmarked containers for chemicals poses a serious risk because it can lead to confusion regarding the contents and potentially result in the misuse of harmful substances. Each of these practices could contribute to unsafe food handling and increase the likelihood of chemical contamination.
