Avocado is a fruit that, once ripe, can be kept for a short time, from 2 to 5 days in the refrigerator. In an attempt to extend the shelf life of avocados, consumers often resort to various tricks, although some of them would not be safe.
One of the viral TikTok tricks that promises to keep fruit green and fresh for up to a month is to submerge whole avocados in water and store them in the refrigerator.

Some users who have put the avocado preservation method into practice have found that it can work, however, the US Food and Drug Administration (FDA) does not recommend the trick.
The FDA’s main concern is the possibility that during storage, when the fruit is submerged in water, bacteria such as Salmonella and Listeria or other pathogens that may be found on the surface of the avocado can multiply and get to the pulpan FDA spokesman told Newsweek.
“Research by FDA scientists has shown that Listeria monocytogenes has the potential to infiltrate and internalize the flesh of avocados when submerged in refrigerated dump tanks within 15 days during refrigerated storage,” shares Newsweek.
If the harmful bacteria have seeped into the flesh of the avocado, even disinfecting the skin of the fruit before cutting will not remove the contamination.
The FDA has found that the prevalence of Listeria monocytogenes in avocado skin samples from 1,615 avocados was 17.73 percent. It has also found Salmonella in various avocado skin samples.
Store avocados for a long time safely
It is possible to keep avocados frozen for months and have them available at any time. It is possible to store them whole and with skin, in halves and without skin, as well as pureed.
Save the Food recommends peeling avocados, pureeing them and mixing with lemon juice (one tablespoon per piece). Avocado puree is ideal for preparing guacamole, salsa or hummus.
To freeze the avocado halves, you just need to separate the pulp from the skin with a spoon and put the halves in a zipper bag. Nutritionist and food technologist Mónica Acha recommends covering the avocado halves with a little lemon juice before putting them into the bag to avoid browning on the surface.
The whole avocado can be kept frozen for up to four months. Freeze the whole avocado and when you want to use it, run it under hot water and let it sit on the counter for 30 minutes. When you can feel it yield to gentle finger pressure, cut the avocado skin into quarters for easy removal. The avocado is ready to be used.
