A New E. Coli Outbreak, Hemolytic-Uremic Syndrome, and Eating In or Out
There’s a newly-identified E. coli strain that’s causing a serious illness called hemolytic uremic syndrome (HUS). The recent cases, mainly in northern Europe, have been attributed to eating raw vegetables like cucumbers, lettuce and tomato. So far, authorities aren’t sure of the exact source.
Like any stomach bug, these bacteria can cause diarrhea, fever and other symptoms related to the gut. When people develop HUS, the kidneys fail and they may need dialysis. (Uremic Syndrome refers to uremia, when toxins normally cleared by the kidneys circulate in the bloodstream and cause problems in other body parts.)
The “H” in HUS is for hemolytic, which describes how red blood cells are destroyed in the bloodstream. This occurs sometimes from effects of a bacterial toxin, such as might happen upon ingestion of a toxic strain of E. coli bacteria. This condition results in jaundice – a visible yellowing of the eyes and skin, and anemia – a paucity of red blood cells.
According to NatureNews, the culprit’s genome has been sequenced. It encodes broad-spectrum beta-lactamases. This means these toxic E. coli will, in general, resist antibiotics that exert their antiseptic powers by means of beta-lactam rings.
What’s my take-home message, as a home-maker and mom?
If I were traveling in areas affected now, I wouldn’t panic or change my plans. But I would avoid eating salad and any raw fruits or vegetables that can’t be peeled. I’d be mindful of foods like guacamole and salsa with fresh cilantro or other imperfectly-washed ingredients. Better to order cooked food, especially in restaurants where you don’t know who’s rinsing the greens.
The same rules apply at home, except that I’ll eat salad and fresh vegetables that I’ve prepared diligently.
Hand-washing after touching any part of a toilet, bathroom sink or faucet is always wise. The point is to avoid accidentally putting germs in your mouth that come from animal or human feces.
My next post will be on another topic, entirely.
