Of all the awful things you wouldn’t want to find in your coffee, botulin falls somewhere between gefilte fish and, say, ricin. If you’re not hip to your lethal toxins, botulin grows at low oxygen levels and causes botulism, a gnarly form of food poisoning that leads to dizziness, fatigue, blurred vision, muscle weakness and—5 to 10 percent of the time—death. (Fun fact: Botox is made from the same toxin. The more you know!)

Good thing you’ll never have to worry about catching it in your daily cuppa, right? Hmm, about that: If you like to drink Death Wish Coffee, the popular brand that claims it’s the world’s strongest coffee at 728 milligrams of caffeine per 12 ounces, you might have a … uh … death wish. The company has announced a massive recall of its cold brew coffee cans because of a potential link to botulin.

Death Wish says its current process “could lead to the growth and production of the deadly toxin, botulin, in low acid foods commercialized in reduced oxygen packaging,” according to the FDA’s official announcement. The recall affects all 11-ounce. Death Wish Nitro Cold Brew cans, and the New York-based company says it’s halting production of the item until “an additional step in the manufacturing process is implemented.”

“Our customers’ safety is of paramount importance, and Death Wish Coffee is taking this significant, proactive step to ensure that the highest quality, safest, and of course, strongest Coffee products we produce are of industry-exceeding standards,” said founder/owner Mike Brown in a statement.

If you bought a can from Death Wish’s website and would like a refund, and also no botulism, please, the company says it will reimburse you within 60 days.
