Final answer:
A pan of chicken wings left out for 7 hours represents a biological hazard and poses a risk of foodborne illnesses due to bacteria growth in the 'danger zone' temperatures.
Step-by-step explanation:
A pan of chicken wings left out on a prep table for 7 hours represents a biological hazard. This is a type of food safety hazard that occurs when food is left at room temperature for extended periods, allowing for the growth of bacteria and other pathogens that can cause foodborne illnesses. The temperature range in which food-borne pathogens can thrive is known as the 'danger zone,' which is between 40°F and 140°F (4°C and 60°C). Since the chicken wings were left out for more than the recommended 2 hours, they are at high risk of contamination and should not be consumed.
During this time, the chicken wings can become contaminated with harmful bacteria like Salmonella or Staphylococcus aureus. If consumed, these bacteria can cause symptoms such as nausea, vomiting, diarrhea, and stomach cramps. It is important to practice proper food handling and refrigerate perishable foods promptly to prevent bacterial growth and foodborne illnesses.
