I haven't read the news in a while, so I was surprised to hear that there was an e.coli outbreak on spinach recently. The outbreak can be traced back to Natural Selection Foods, in San Juan Bautista, California. Natural Selection Foods packages their produce to the following brands: Bellissima, Cheney Brothers, Coastline, Compliments, Cross Valley, D'Arrigo Brothers, Dole, Earthbound Farm, Emeril, Farmers Market, Fresh N' Easy, Fresh Point, Green Harvest, Hy-Vee, Jansal Valley, Mann, Mills Family Farm, Natural Selection Foods, Nature's Basket, O Organic, Premium Fresh, President's Choice, Pride of San Juan, Pro-Mark, Rave Spinach, Ready Pac, River Ranch, Riverside Farms, Snoboy, Superior, Sysco, Tanimura & Antle, The Farmer's Market and Trader Joe's.
The bacteria is inside the spinach, so a simple washing won't take care of e.coli.
This whole thing has made me want to defend coli, since most news sources don't bother to point out that it's the (rare) pathogenic O157:H7 strain, rather than the benevolent kind that makes up much of your gut flora.
