Pesticide residue refers to the trace amounts of pesticides that remain on food after it has been treated with pesticides. Synonyms for pesticide residue include chemical residues, agrichemical contamination, pesticide contamination, chemical contaminants, and toxic residues. Pesticide residues can have a negative impact on human health and the environment, so efforts are taken to minimize their presence. This can include using alternative methods for pest control, washing produce thoroughly, and setting strict limits on acceptable levels of pesticide residues in food. It is important to be aware of potential pesticide residues in the food we eat and to take steps to minimize our exposure to them.
