Which of the following methods is typically not acceptable for pest control?

Tracking powder is generally not considered an acceptable method for pest control in many food service establishments. This technique involves the application of toxic substances that can pose significant hazards in food preparation and service areas. When tracking powder is used, there is a risk of cross-contamination, as the powder can come into contact with food, food preparation surfaces, or utensils. The presence of toxicants in the environment can lead to foodborne illnesses or chemical exposure for workers and patrons.

In contrast, the other methods mentioned—such as glueboards, ultraviolet fly traps, and rodent bait traps—are more commonly accepted in food safety practices. Glueboards can effectively capture flying insects without posing a contamination risk to food. Ultraviolet fly traps attract flies and trap them without the use of chemical toxicants directly in food areas. Rodent bait traps, when used correctly and placed in secure locations, can help control rodent populations without placing toxic substances in areas where food is kept. These methods align better with food safety regulations and best practices, making them more acceptable and effective for pest control in food service environments.
