Which establishment is NOT part of Group 1?

The establishment that is not part of Group 1 is the police station. Group 1 typically includes establishments that are involved in food handling and preparation or have certain customer service functions.

Public markets and bakeries engage directly in activities pertaining to food production, sales, and service, making them part of Group 1 due to their role in public health and safety within the food industry. Manufacturing industrial plants might also include elements associated with food production, depending on their specific activities.

On the other hand, police stations serve a different primary function focused on law enforcement and public safety rather than food service or production, which distinguishes them from the other options in this context. Thus, police stations do not fit the criteria for Group 1 as their operations are unrelated to the handling and preparation of food.
