18. Overheating Is a Real Risk

Heating Teflon-coated pans above 500°F (260°C) can cause the coating to break down and release toxic fumes. These fumes are notorious for causing “polymer fume fever” in humans—a temporary, flu-like illness—and can be deadly to pet birds with highly sensitive respiratory systems. To stay safe, always cook on medium or low heat and never leave empty pans on a hot burner. (Source: CDC)
