How often is listeria lurking in avocados?
The FDA makes it a practice to test certain foods to see whether they’re contaminated with salmonella, E. coli, or listeria. The focus of a new investigation: avocados. Federal officials collected a whopping 1,615 avocados — both domestic and imported — and either scooped out the centers or swabbed the outside. Of the 1,254 “pulp” samples, just three tested positive for listeria. Of the 361 skin samples, 64 tested positive for listeria — which officials say should be a reminder to always wash your produce. They did the same thing with hot peppers, and found that just under 3 percent tested positive for salmonella.
