But an FDA official told \"Good Morning America\" the agency \"does not recommend this practice.\"

\"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,\" the official said in a statement to \"GMA.\"

\"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,\" they added. \"In this case, even surface disinfecting the avocado skin prior to slicing would not be able to remove the contamination.\"
