What is a sign that food may be unsafe?

A strong smell is a clear sign that food may be unsafe. When food emits an unpleasant or overpowering odor, it often indicates that spoilage or contamination has occurred. This can happen when food is past its expiration date or has been improperly stored, allowing harmful bacteria to grow. Recognizing this warning sign can help prevent foodborne illnesses, as consuming spoiled food can lead to serious health issues.

In contrast, bright color and fresh texture could be misleading as they might suggest the food is fresh and safe to eat. However, these attributes alone do not guarantee the absence of harmful bacteria or foodborne pathogens. Similarly, a short shelf life is not inherently indicative of unsafe food. Many perishable items are meant to be consumed quickly for optimal quality but can still be safe if handled properly. Thus, a strong smell serves as a more reliable and immediate indicator of potential food safety issues.
