Beef is one of the most popular and widely consumed meats around the world. Rich in protein, iron, and essential nutrients, it plays a key role in many diets. However, not all beef sold at the market is safe to eat. According to experienced butchers, certain types of beef can pose serious health risks and should be avoided at all costs—even if offered for free.

Here are 5 types of beef you should never buy:

1. Beef with an unusual color
   Fresh beef should have a bright red color. If the meat appears gray, brown, or has dark spots, it may be old, spoiled, or improperly stored. Consuming it could lead to food poisoning.

2. Beef with a slimy or sticky texture
   Good-quality beef feels firm to the touch. If the surface is sticky, slimy, or overly wet, it’s a warning sign of bacterial growth and spoilage.

3. Beef with a strange odor
   Fresh beef has a mild, meaty smell. A sour, ammonia-like, or pungent odor indicates the meat is spoiled and dangerous to consume.

4. Excessively fatty or injected beef
   Some low-quality beef may be injected with water, chemicals, or preservatives to increase weight and appearance. This kind of meat lacks nutritional value and can harm your health.

5. Beef sold at suspiciously low prices
   If the price seems too good to be true, it probably is. Cheap beef may come from sick, old, or unregulated sources that bypass safety checks.

Expert advice: Always purchase beef from reputable sellers, check the color and smell, and never compromise on quality for the sake of saving money. Eating unsafe beef not only ruins the taste of your meal but also puts your health at serious risk.
