Nontyphoid salmonellosis caused bySalmonella enterica is the most common bacterial food-borne illness in humans, and fresh produce, including tomatoes, is a common vehicle. Accumulating data indicate that human enteric pathogenic bacteria, includingS. enterica , interact actively with plants. Tomato plants were inoculated withS. enterica to evaluate plausible contamination routes and to determine if the tomato cultivar affectsS. enterica colonization.S. enterica population levels on tomato leaves were cultivar dependent.S. enterica levels onSolanum pimpinellifolium (West Virginia 700 [WVa700]) were lower than onS. lycopersicum cultivars.S. enterica preferentially colonized type 1 trichomes and rarely interacted with stomata, unlike what has been reported for cut lettuce leaves. EarlyS. enterica leaf colonization led to contamination of all fruit, with levels as high as 105 CFU per fruit. Reduced bacterial speck lesion formation correlated with reducedS. enterica populations in the phyllosphere. Tomato pedicels and calyxes also harbored largeS. enterica populations following inoculation via contaminated water postharvest. WVa700 green fruit harbored significantly smallerS. enterica populations than did red fruit orS. lycopersicum fruit. We found that plants irrigated with contaminated water had largerS. enterica populations than plants grown from seeds planted in infested soil. However, both routes of contamination resulted in detectableS. enterica populations in the phyllosphere. PhyllosphereS. enterica populations pose a risk of fruit contamination and subsequent human disease. RestrictingS. enterica phyllosphere populations may result in reduced fruit contamination. We have identified WVa700 as a tomato cultivar that can restrictS. enterica survival in the phyllosphere.

Colonization of Tomato Plants by Salmonella enterica Is Cultivar Dependent, and Type 1 Trichomes Are Preferred Colonization Sites
