Sure, Costco may have awesome pizza and heaps of cheap wholesale products. But not everything is as good as it may seem. Oftentimes, the famous store sells poison. That’s right. And below is the list of the top 5 poisonous foods one can buy at Costco.

Costco: 5 Poisonous Foods You Can Buy in The Store

Costco Poisonous Foods 1: TOMATOES

Everyone’s favorite pasta sauce comes from poison. As a member of the nightshade family, tomatoes have glycoalkaloids. These are natural pesticides produced by nightshades and are known to be toxic. It would take 227 mg of this toxin to kill a mouse. What’s not good for a mouse – ain’t good for a human.

Costco Poisonous Foods 2: POTATOES

Another member of the nightshade family, potatoes with their solanine content have the potential to cause harm. In large doses, solanine can cause gastrointestinal symptoms, hallucinations, paralysis, and even death.

Even though you would have to eat an enormous amount of potatoes to feel the effects of solanine poisoning, you’re better off sticking with those Costco hot dogs instead.

Costco Poisonous Foods 3: CASHEWS

Well, cashew shells to be specific. The cashew is not a real nut. True nuts, like hazelnuts, from a hard wall around the seed. Not Cashews. Cashews have a lining around the seed that is full of a toxic fluid. This is the same fluid found in poison ivy and sumac, which are relatives of the cashew. Costco probably doesn’t sell shelled cashews, but be on the lookout just in case.

Costco Poisonous Foods 4: ALMONDS

Yes, even this “superfood” can cause us harm. Like cashews, almonds are not nuts. They are seeds. If they are not introduced to some kind of heat source, almonds are extremely poisonous. These seeds are chock full of cyanide. For this reason, almonds are illegal in many countries.

Costco Poisonous Foods 5: APPLES

They say an apple a day will keep the doctor away. Apparently, this old saying is a bit outdated nowadays. Technically, apples are not bad for you. However, their seeds contain ridiculous amounts of poison. Just the seeds from one apple won’t kill you, but keep it up and you’ll end up like Snow White. She was the one with the poisonous apple, right? Or was that Sleeping Beauty? Those Disney princesses are all the same anyway.
