May 25, 2022 -- The U.S. Food and Drug Administration warns the public not to follow an idea spread on Tik Tok for storing avocados in water.
Over the last few months, Tik Tok creators have posted videos of avocados being stored in containers of water in the refrigerator. The creators and commenters say the practice keeps the fruit fresh for weeks, Newsweek reported.
But the FDA says you should find another way to store your avocados.
"The FDA does not recommend this practice," the agency said in a statement to Newsweek. "The main concern is with the possibility that any residual human pathogens (i.e. Listeria monocytogenes, Salmonella spp., etc.) that may be residing on the avocado surface may potentially multiply during the storage when submerged in water.
"In addition, research performed by FDA scientists has shown that Listeria monocytogenes has the potential to infiltrate and internalize into the pulp of avocados when submerged in refrigerated dump tanks within 15 days during refrigerated storage. In this case, even surface disinfecting the avocado skin prior to slicing would not be able to remove the contamination."
The FDA said scientists studied skin samples from 1,615 avocados and found the overall prevalence of Listeria monocytogenes to be 17.73%.
The scientists also discovered that putting avocados in refrigerated water only allowed Listeria monocytogenes to migrate from the outside of the fruit to the inside, Newsweek reported.
