Milwaukee NBC affiliate, TMJ4, reported on their investigation into whether spinach now on the shelves in Wisconsin supermarkets is safe and free of pathogenic bacteria.

The investigation did not uncover any E. coli or other bacteria on spinach sampled from Milwaukee stores, but consumers are still skeptical about whether they should eat bagged spinach and lettuce from California’s Salinas Valley.

The food industry and Dr. G. Richard Olds from the Medical College of Wisconsin both assert that spinach and other vegetables are safe to eat. However, with the number of E. coli outbreaks traced to produce in recent years, consumers are still concerned.
