Exposed: the health risks of leaving corn tortillas unrefrigerated

Corn tortillas, a staple in Mexican cuisine, are known for their versatility and affordability. However, their shelf life can be a concern, especially when it comes to leaving them out at room temperature. In this comprehensive guide, we’ll delve into the intricacies of corn tortilla storage and answer the burning question: Can corn tortillas be left out?

The Perils of Leaving Corn Tortillas Out

Corn tortillas, like most perishable foods, are susceptible to spoilage when left out for extended periods. The warm and humid environment outside the refrigerator provides an ideal breeding ground for bacteria, which can cause the tortillas to develop mold, yeast, and other harmful microorganisms.

Understanding the Shelf Life of Corn Tortillas

The shelf life of corn tortillas depends on several factors, including:

• Packaging: Unopened corn tortillas in airtight packaging can last for up to 2 weeks at room temperature.
• Temperature: Exposure to high temperatures accelerates the growth of bacteria. Store corn tortillas in a cool, dry place below 70°F (21°C).
• Moisture: Keep corn tortillas away from moisture, as it can create a breeding ground for mold.

How Long Can Corn Tortillas Be Left Out?

As a general rule, corn tortillas should not be left out at room temperature for more than 2 hours. After this time, the risk of bacterial growth increases significantly.

Signs of Spoiled Corn Tortillas
