What must be provided for customers according to food safety regulations?

Ensuring that toilet rooms are available for customers is a crucial aspect of food safety regulations. The provision of sanitary and accessible restroom facilities is necessary to maintain hygiene standards within food establishments. Clean toilet facilities help prevent foodborne illnesses by allowing customers the means to practice proper personal hygiene, such as handwashing after using the restroom.

Handwashing is a vital aspect of food safety, as it significantly reduces the risk of transmitting pathogens. By ensuring that customers have access to toilet rooms equipped with handwashing stations containing soap and sanitary towels, food service establishments contribute to a safer dining environment.

The other choices do not align with mandatory requirements under food safety regulations. Complimentary meals, regular discounts, and water bottles may enhance customer service but are not regulatory obligations aimed at protecting public health. Therefore, the requirement for toilet rooms directly supports the overarching goal of food safety: minimizing the risk of contamination and maintaining public hygiene.
