Final answer:
Soon-to-be caterers must obtain a food handler's permit or a food safety certification, which demonstrates their knowledge and skills in handling food safely.
Step-by-step explanation:
In order to obtain legal permission to prepare food in a private kitchen for public consumption, soon-to-be caterers must obtain a food handler's permit or a food safety certification. These certifications vary by location, but they typically involve completing a food safety training course and passing an exam.
The purpose of these certifications is to ensure that caterers have the knowledge and skills necessary to handle food safely and prevent foodborne illnesses. By obtaining this permit or certification, caterers demonstrate their understanding of proper food handling techniques, including storing, preparing, and serving food in a sanitary manner.
For example, in the United States, the ServSafe certification is widely recognized and accepted as evidence of a caterer's competence in food safety. This certification covers topics such as foodborne illness, contamination, safe food handling practices, and personal hygiene.
