Kitchen and dining

Prisons generally have to provide food for a large number of individuals, and thus are generally equipped with a large institutional kitchen. There are many security considerations, however, that are unique to the prison dining environment. For instance, cutlery equipment must be very carefully monitored and accounted for at all times, and the layout of prison kitchens must be designed in a way that allows staff to observe activity of the kitchen staff (who are usually prisoners). The quality of kitchen equipment varies from prison to prison, depending on when the prison was constructed, and the level of funding available to procure new equipment. Prisoners are often served food in a large cafeteria with rows of tables and benches that are securely attached to the floor. However, inmates that are locked in control units, or prisons that are on "lockdown" (where prisoners are made to remain in their cells all day) have trays of food brought to their cells and served through "chuck-holes" in the cell door. Prison food in many developed countries is nutritionally adequate for most inmates.
