Storing Avocados in Water: FDA Cautions Against This Risky Trend

Everyone loves a good kitchen hack. But avocados that stay fresh for a month? If it sounds too good to be true, it probably is.

The FDA is speaking out against a viral TikTok and Facebook trend that shows users storing whole or cut avocados in water to keep them fresh for longer.

In one video, the TikTok user @sidneyraz stored half an avocado in a container of water overnight, taking it out the next day to find it was still ripe and green. Another user, @shamamamahealing, stored an uncut avocado in a jar of water in the fridge, revealing perfectly smooth, green fruit on the inside after a two-week soak. Her video quickly went viral, amassing more than six million views before she took it down, Newsweek reported.

On the surface, the science seems plausible. Avocados start to turn brown when they’re exposed to oxygen, in a process called oxidation, says Matt Regusci, the director of growth at ASI Food Safety, a consulting firm in St. Anne, Missouri, that specializes in food safety inspections and certification. “The same thing happens with apples and potatoes,” he explains. “There is nothing wrong with the browning as far as a health risk is concerned, it just doesn’t look good.”
