Another food advisory… this time from the FDA in the States. A report released by the FDA in early December found that about one in five avocados tested positive on the outer skin (or peel) for Listeria monocytogenes, whose infection listeriosis can cause a variety of health issues, including nausea, vomiting and diarrhea. The bacteria was also found in less than one percent of avocado flesh.
Why does this matter if you don’t consume the skin? The potential issue is that when you cut through the avocado’s pebbly skin, bacteria could be transferred to the knife. And then the knife could contaminate the avocado flesh. “Even if you plan to cut the rind or peel off the produce before eating, it is still important to wash it first so dirt and bacteria aren’t transferred from the knife onto the fruit,” warned the FDA.
The same logic can be applied to other fruits and vegetables that are either peeled or chopped.
