ARS The
research, which is being conducted with the sprouted seeds of broccoli, radish,
alfalfa, and mung bean, could lead to new and more effective tactics to thwart
Salmonella not only in sprouts, but in other fresh produce—and perhaps even in
meats and poultry—as well. The ARS investigation into the key Salmonella genes
may be unique. So far, the experiments in which a gene or genes have been
knocked out of lab strains of the pathogen have yielded a Salmonella that is
only one-tenth as effective in colonizing fresh sprouts. Now scientists need to
determine which of the 4,000 to 5,000 Salmonella genes are missing or disabled
in that strain. The researchers expect that help in answering this question will
come from scientists elsewhere who are collaborating in an international effort
to determine the makeup and function of all Salmonella genes. Besides adding
color, taste, and texture to salads, sandwiches, soups, and other dishes,
sprouts provide protein, fiber, and antioxidants such as vitamin C.
