What items are considered hazardous in the preparation of food?

Jewelry and bread ties are considered hazardous in the preparation of food primarily due to their potential to contaminate food products and pose safety risks. Jewelry can harbor bacteria and other contaminants, which can transfer to food during preparation, thereby compromising food safety. Additionally, loose items like bread ties may inadvertently fall into food, leading to physical hazards that could cause choking or injury.

While fruits and vegetables are ingredients typically used in cooking, and packaging materials may contain chemicals, they are not inherently hazardous in the same way as jewelry can be when worn during food preparation. Cleaning supplies, although dangerous if ingested, do not directly pertain to the food preparation process unless there is improper storage or handling leading to contamination. Thus, jewelry and bread ties stand out as significant safety concerns in the kitchen environment.
