What is an example of physical contamination?

Physical contamination refers to the introduction of foreign objects into food that can cause injury or discomfort when consumed. The presence of hair, metal shards, or any other foreign objects in food clearly falls under this category, as these items are not meant to be part of the food and can pose a safety risk to consumers. Ensuring that food is free from such contaminants is a vital part of food safety practices, as it directly impacts the health and well-being of those consuming the food.

In contrast, the other options represent different types of food safety issues. Dirty utensils pertain to biological contamination, which involves harmful microorganisms affecting food safety. The presence of bacteria in raw chicken is also a biological hazard, as these microorganisms can lead to foodborne illnesses. Lastly, improperly stored dairy products relate to spoilage and potential chemical contamination due to improper handling or storage conditions, but they do not fall under the category of physical contamination. Understanding these distinctions is critical for food handlers who must maintain high standards of food safety.
