What preventative measure can be taken to reduce the risk of pests in a food establishment?

Sealing cracks and crevices is an effective preventative measure to reduce the risk of pests in a food establishment because it eliminates potential entry points for various pests, such as rodents, insects, and other critters. Pests often find tiny gaps in walls, floors, and around fixtures where they can easily gain access to the facility. By sealing these openings, you create a barrier that not only keeps pests out but also limits their ability to breed and establish nests within the establishment, thereby promoting a safer and cleaner environment for food preparation and service.

In contrast, keeping doors and windows open can actually invite pests into the facility, while using strong pesticides may address existing infestations but does not prevent new ones from entering. Additionally, storing food on the floor can attract pests and increase the likelihood of contamination, making it an unsafe practice.
