6. When to Worry: Smell, Color, and Texture Red Flags

While the white strings themselves are usually harmless, other indicators can reveal whether your meat is spoiled. Check for an off-putting odor; fresh beef should have a clean, slightly metallic smell. A sour or rancid odor is a red flag.

Examine the color and texture as well. The meat should be a consistent color—usually a rich brown after cooking—and should not have any slimy or sticky coating. If the meat feels tacky or has a greenish hue, it may not be safe to eat.
