Listeria in leafy greens: Consumer Reports

Consumer Reports

CONSUMER REPORTS — There have been plenty of headlines recently about people getting sick from a virulent strain of E-coli in lettuce and other leafy greens. This sparked the food safety experts at Consumer Reports to test a variety of greens out there in the marketplace. The team found a potentially dangerous type of listeria, in several samples. Here’s who is most vulnerable –– and some advice on how to keep greens in your diet, while minimizing your risk.

Fresh salads often top the menu during these dog days of summer. But Consumer Reports found some very real reasons to take care with greens that aren’t cooked.

New Consumer Reports’ tests of 2-hundred-84 samples of fresh greens, found six of the samples tainted with Listeria monocytogenes. A potentially deadly bacteria.

The tainted samples included red and green leaf lettuce, spinach and kale. Both conventional and organic. Packaged and loose.

Be aware listeria cannot readily be washed off with water.

“Washing greens can get rid of dirt and some pesticides, but not all bacteria. That’s because bacteria can adhere to the surface of leaves, and also get stuck in microscopic crevices,” said Sana Mujahid, Consumer Reports Food Saftey Expert.

Scientists at Consumer Reports say it’s important to know that not everyone exposed to listeria, gets sick.

But some people are more vulnerable –– including pregnant women, older adults, infants and young children, and anyone with a compromised immune system. If that’s you, carefully consider whether to eat raw greens, entirely.

“Leafy greens are super nutritious — and for most people, the nutritional benefits far outweigh the potential contamination risks. But if you are in that at-risk category, the safest thing to do is to stick with greens that you can cook,” Mujahid said.

Experts also advise to eat leafy greens soon after you buy them, before bacteria has a chance to multiply.
