2. Brands to avoid are Natural Selection Foods (San Juan Bautista, Cal.), River Ranch (Salinas, Cal.) and RLB Food Distributors (West Caldwell, N.J.), all of which have recalled their bagged spinach and spinach-containing salad mixes.
3. If you still can't do without your spinach, cook it. E. coli 0157 on fresh produce can be killed by heating at 160 F for at least 15 seconds.
4. So far, frozen spinach appears to be safe. It's been cooked, and is often cooked again after thawing, so should be unaffected by the current E. coli 0157 outbreak.
5. When fresh spinach returns to the shelves, wash it thoroughly before eating. It's not as good as cooking when it comes to killing bacteria, but a good dousing with water will remove a lot of bugs clinging to the leaves.
