Salmonellae in health foods.

Various health food products of different brands were purchased from stores in the metropolitan Atlanta area. These foods were examined for the presence of salmonellae by fluorescent-antibody and cultural methods. Included in the study were tablets of alfalfa, parsley, kelp, wheat bran, enzyme, bone meal, and vitamins. Beef liver powder and tablets and granola cereal were also studied. Salmonella minnesota, Salmonella anatum, and Salmonella derby were isolated from two of three lots of beef liver powder from one manufacturer. All other products were negative.
