The advice is simple: just place the avocados in a container, fill it with cold water and store it in the refrigerator.

This trick – billed as a magic solution by members of the social network – supposedly allows you to keep avocados fresh up to a month, according to those making the hit videos, which count several million views.

What they don’t tell you – or rather, what they don’t know – is that your fruit could make you sick if stored in this way.

According to the FDA, the US Food and Drug Administration, potentially harmful bacteria on the skin of avocados could multiply when the fruit is stored submerged in water.

This could then be transferred when preparing the avocados. A spokesperson also told Newsweek that listeria monocytogenes could potentially infiltrate the flesh of the fruit within two weeks.

In a report published in 2018, US health authorities had already identified the presence of this bacterium, which can lead to fever, vomiting and digestive disorders.

In a sample of 1,615 avocados, 17% were found to have Listeria monocytogenes on their skins. As such, it is recommended to wash the skin of avocados before preparing them.
