What is a common way to prevent pests in a food establishment?

Regularly clearing and cleaning waste areas is an effective method to prevent pests in a food establishment. Pests such as rodents and insects are attracted to food waste, spills, and debris. By maintaining cleanliness in and around waste areas, you minimize the food sources and hiding places that pests rely on for survival. This not only helps in preventing infestations but also promotes a hygienic environment that is essential for food safety.

The other options do not effectively address pest prevention. Keeping doors and windows open allows for easy access for pests and does not provide a barrier to them. Using strong fragrances is ineffective, as many pests are not deterred by scents and may simply be attracted to food sources regardless of odors. Leaving food uncovered is particularly problematic, as it provides a direct and inviting source of food for pests, increasing the likelihood of problems.
