What is considered the safest method for eliminating rodents in a food service environment?

Using traps is considered the safest method for eliminating rodents in a food service environment due to several reasons. Traps are designed to capture rodents without the use of hazardous chemicals, making them a safer choice for areas where food is prepared and served. This minimizes the risk of contamination that can occur with poison baits, which may leave behind toxic residues if a rodent dies in an inaccessible area or if non-target animals or pets consume the bait.

Moreover, traps allow for a more humane approach, as they can be designed either to humanely capture rodents for later release or to kill them instantly. This method also enables operators to monitor rodent activity more effectively, as trapped rodents can indicate the level of infestation or entry points needing attention.

Ultrasonic devices, while marketed as a deterrent for rodents, have varying effectiveness and often do not provide a reliable solution on their own. Dirt and debris removal is essential for preventing infestations, but it does not actively eliminate existing rodents. Thus, traps represent the most practical and effective control method in maintaining a safe and sanitary food service environment.
