A study conducted at the Santa Anita Wholesale Market in Lima, Peru, has found high levels of pesticides in various foods, with Chinese onions having up to 10,900% more than permitted limits. The study examined over 60 food samples from five markets, finding that 47% were unsuitable for consumption due to excessive agrochemicals. Some samples contained banned pesticides like fipronil and bifenthrin, which can harm health. Despite a ban, chlorpyrifos, a pesticide harmful to children, was also detected. The National Agrarian Health Service of Peru is taking steps to improve food supervision and reduce pesticide use.
