Not everything that looks edible is safe to eat — especially when it comes to common items we’ve grown up seeing in our kitchens. Some foods that seem harmless can actually pose serious health risks, particularly to older adults with weakened immunity or chronic conditions. Here are five foods that may be sitting in your home right now — and why you should consider throwing them out.

1. Expired Canned Goods

Canned food is a pantry staple, but expired or rusted cans can become dangerous. Damaged or old cans may harbor botulism bacteria, which produce a toxin that can lead to serious illness or even death.

Why it’s harmful: Botulism can cause paralysis, breathing difficulties, and requires emergency treatment.

What to do: Check expiration dates and toss out any swollen, leaking, or rusted cans — especially if your parents tend to save food "just in case."

2. Moldy Bread or Rice

It might be tempting to just cut off the moldy part of bread or rinse old rice, but mold can spread invisibly and release dangerous mycotoxins. These toxins can be especially harmful to the liver and immune system.

Why it’s harmful: Mycotoxins are linked to respiratory issues, nausea, and even cancer with long-term exposure.

What to do: Don’t risk it — if you spot mold, toss the whole thing.

3. Reused Cooking Oil

Some people reuse frying oil multiple times to save money, but reheated oil breaks down and produces harmful free radicals and trans fats. These compounds are associated with heart disease, inflammation, and increased cancer risk.

Why it’s harmful: Regular consumption can damage blood vessels and raise cholesterol levels.

What to do: Encourage your family to use fresh oil for each round of deep frying, or opt for healthier cooking methods like steaming or baking.

4. Old Dried Spices

That paprika from 2008 may still be in the spice rack, but over time, spices lose potency — and worse, they can grow mold or bacteria, especially if not stored properly. Some imported spices may even contain heavy metals if not regulated.

Why it’s harmful: Long-expired spices can trigger allergies or digestive upset and may contain contaminants.

What to do: Do a spice rack clean-out every 6–12 months. If in doubt, throw it out.

5. Green or Sprouted Potatoes

Many people don’t realize that green or sprouted potatoes contain solanine, a natural toxin that can cause vomiting, headaches, and even neurological symptoms in large amounts.

Why it’s harmful: Solanine poisoning is rare but real — and older adults are more susceptible to its effects.

What to do: If a potato is green or has grown long sprouts, it’s safer to discard it entirely rather than trying to salvage it.
