Which of the following can cause a food establishment to be closed?

The closure of a food establishment is typically a direct response to serious violations of public health standards. When a food establishment fails to correct identified public health hazards, it can pose significant risks to consumer safety. Public health hazards may include issues like improper food storage, unsanitary conditions, or any factors that could potentially lead to foodborne illnesses. Regulatory agencies prioritize the health and safety of the public, and failure to address these critical issues can result in immediate closure until the establishment can rectify the problems.

In this context, a valid health permit is necessary for operation, and low customer ratings, while they may affect business, do not directly result in closure. Introducing a new menu is not a reason for closure as long as all food safety guidelines are followed. Thus, only the inability or refusal to correct public health hazards represents a valid cause for a food establishment to be closed.
