Abstract
Non-typhoidal Salmonella has emerged as one of the problematic human pathogens associated with fresh produce, nuts, and complex foods containing them. Recent research shows that some varieties of plants are more “resistant” to colonization by the pathogens than others. This raises the intriguing possibility that cultivar selection could be used to identify crop varieties that may be less conducive to proliferation of human pathogens. This 3-page fact sheet provides up-to-date information about tomato production practices and their relationships with Salmonella.
