"ecoli" news and stories

Researchers at the USDA have developed an edible coating that will actually kill bacteria on fresh produce. It is intended to be an alternative to conventional or chemical produce washes that will keep the food just as fresh, if not fresher, and reduce the risk of food-borne illness that is associated with fresh produce. The coating is made of apple puree and oregano oil. The oregano oil is a natural antibacterial agent and did a better job at eliminating bacteria than other oils, while the apple puree helps the coating adhere to the fruit/vegetable and takes the edge off the oregano flavor. So far, it has only been tested on E. Coli, where the oregano has been shown to kill at least half of all present bacteria in under 3 minutes. The are planning on developing wrappers in other flavors, as well as targeting different bacteria in the future, including salmonella and listeria.

The products could be commercially available in as little as two years, but they are now being tested by some selected companies and stores.

Only a few days after we were told that it was once again safe to eat spinach, the FDA issued a recall on lettuce from the Salinas-based Nunes Co. The recall only applies to lettuce purchased from October 3-6 in seven western states: Oregon, Idaho, Montana,California, Nevada, Washington and Arizona, and "the recalled lettuce was packaged as "Green Leaf 24 Count, waxed carton," and "Green Leaf 18 Count, cellophane sleeve, returnable carton." Packaging is stamped with lot code 6SL0024."

The reason that the lettuce was recalled was due to a concern over a possibly E.coli contamination in the water supply to the fields, although no E.coli has been found in any of the lettuce and no people have reported illness. The owner of the family-run company says that they have strict safety protocols, which were strengthened when the "spinach scare" broke out.

At this point, all lettuce covered by the recall should be off shelves, but it could be a good idea to check the bags in your fridge just in case.

Now that more than 100 cases of E. coli infections and one fatality have resulted from contaminated bagged spinach, the National Restaurant Association has recommended that restaurants remove spinach from their menus, at least for the time being. McDonald's and several other chains, including California Pizza Kitchen, have already done so. The infections have been reported in 19 states so far and the cause has not yet been confirmed, but it is now suspected that contaminated irrigation water, which the spinach is exposed to when it is packed in the field, may have been a contributing factor.

The FDA is recommending avoiding all fresh spinach or salad blends with spinach, even spinach that is being sold at farmers markets. Washing it will not kill the bacteria and can even spread it around. Similarly, while cooking spinach can kill E. coli, you still run the risk of contamination just from handling it. If you really have your heart set on making a spinach dish, frozen spinach is the safest choice.
