Final answer:
Service animals are typically the only animals allowed in food establishments where customers are present to prevent health risks.
Step-by-step explanation:
The type of animal that may typically be brought into an area of the food establishment where customers are generally allowed is limited by health regulations to prevent the spread of disease. Most often, the only animals permitted are service animals, such as guide dogs for the blind. These animals receive special training to behave appropriately in public places, including restaurants and other food service venues. Other animals, including pets or animals for emotional support, are generally not allowed in areas where food is served or prepared due to concerns over health and safety.
