The Five “Most Dangerous” Expired Condiments Hiding in North Dakota Kitchens

1. Mayonnaise & mayo-based dips – Unopened, mayo lasts three to four months, but once opened, it’s only good for two months. That includes tartar sauce, aioli, and other mayo-based dips—they expire fast. If it smells off, toss it.

2. Salad dressing – Creamy dressings with eggs or cheese should be used within two months. Oil-based dressings last longer.

3. Ketchup & barbecue sauce – Once opened, they’re only good for six months. If the color changes, pitch it.

4. Mustard – The vinegar helps it last longer, but after a year, it’s time to replace it.

5. Soy sauce – It won’t last forever. After about a year, it starts to lose flavor.

Check for changes in color, texture, or smell—if something seems off, it’s better to be safe than sorry. Nobody wants to ruin a perfectly good meal with a bad batch of sauce! Now might be a good time to do a fridge (or pantry) clean-out before grilling season rolls back around.
