Foodservice medical exams are more stringent as compared to entry-level medical exams. This is due to the special nature of the restaurant industry as it relates to food safety and hygiene, as well as contact with a large number of customers. Catering medical exams usually involve a more comprehensive and detailed examination of employees, including knowledge of food handling and hygiene, hand hygiene, infectious diseases and food allergies. Foodservice physicals also require more stringent physical health indicators to ensure that employees do not pose potential health risks to food and customers while on the job.
