When transporting TCS food off-site-such as for catering or delivery to a satellite kitchen-the containers used must befood-grade, leak-proof, and able to be tightly covered. Ametal pan with an aluminum foil cover(or a tight-fitting lid) is a suitable choice because the metal is non-absorbent and durable, and the cover protects the food from physical contaminants, pests, and splashing during transit.
Using an uncovered pan (Option A) is a major violation as it exposes food to environmental hazards. A produce box (Option B) is not suitable for prepared TCS foods because the cardboard or plastic coating may not be easily cleanable or leak-proof enough for cooked items, and it is not intended for multi-use with cooked foods. A chemical bucket (Option D) is extremely dangerous; even if it is cleaned, chemical residues can leach into the food, causing toxic-metal or chemical poisoning. Only containers explicitly labeled as
"food-safe" should be used. Furthermore, during transport, these containers should be placed inside insulated carriers to maintain safe temperatures ($135^{\circ}F$ or higher for hot food; $41^{\circ}F$ or lower for cold food). The manager's responsibility is to ensure that the "Flow of Food" remains secure and sanitary even when the food leaves the primary facility.
