设施、清洁与虫害第 311 / 320 题
Why should a food establishment hire a licensed Pest Control Operator (PCO) rather than have kitchen staff apply pesticides themselves?
a.Because staff pesticides are always cheaper
b.Because a licensed PCO is trained to select, apply, and store pesticides safely and legally near food
c.Because staff are not allowed to see any pests
d.Because the PCO also washes the dishes
解析
A licensed pest control operator has the training and legal authorization to choose the right products, apply them safely around food, and store them properly, minimizing the risk of chemical contamination. Untrained staff can misapply pesticides and contaminate food or surfaces. Using a PCO is the accepted practice within an Integrated Pest Management program.
