Under food safety regulations, every food service establishment is required to have one outlet to ensure sanitary and safe food. However, under certain circumstances, two salad establishments can **** use one outlet, provided that they comply with the requirement that there is no risk of cross-contamination between the salad establishments, e.g. by using different ingredients and tools; that the outlets are properly cleaned and sanitized to ensure food safety, and that the owner holds a legal food business license and complies with the relevant hygiene standards and regulations. Therefore, two salad stores may **** use a single food outlet, provided that the above conditions are met.
