"Right now, the only spinach we're saying shouldn't be consumed" is spinach traced back to Natural Selection Foods of San Juan Bautista, Calif., said David Acheson, chief medical officer at the agency's Center for Food Safety and Applied Nutrition.
Other spinach -- which the agency had warned consumers to avoid two weeks ago -- is "as safe as it was before this event," Acheson said.
Natural Selection Foods issued a recall Sept. 15 of all products containing spinach with "Best if used by" dates of Aug. 17 through Oct. 1. That included bagged greens under more than two dozen brand names, The San Francisco Chronicle reported.
So far, 188 people in 26 states and Canada have been sickened or killed by spinach tainted with E. coli bacteria traced to Natural Selection Foods, Acheson said.
