“…Manure contamination can be from the farm or during packing (Harris et al, 2003). In 1999, a multi-state outbreak of Salmonella enterica serotype Baildon (a rare serotype) was associated with raw, domestic tomatoes in the United States (Cummings K et al, 2001). This large outbreak resulted in 86 confirmed cases of salmonellosis.…”

“…Since 1998, 12 outbreaks caused by S. enterica were linked to tomato consumption in the United States (CDC, 2005;Cummings et al, 2001). Tomato contamination was also reported to originate from the fields where the tomatoes were grown (CDC, 2007).…”

Tomatoes have recently been implicated as an important vehicle in outbreaks of produce-associated salmonellosis. Traceback reports suggested that pre-harvest contamination of Salmonella enterica might be the main reason for these outbreaks; however, the site of pathogen attachment remains unclear. Therefore, it is important to investigate the mechanisms of Salmonella contamination of fresh produce. To trace the presence of Salmonella in soil and plants, Salmonella Enteritidis transformed with a pEGFP plasmid vector (S. Enteritidis-EGFP) was used. Soil was artificially contaminated with S. Enteritidis-EGFP at 10 4 , 10 6 or 10 8 CFU/g, followed by cultivation of tomato plants in the contaminated soil. Samples of the soil and each organ of the tomato (fruit, stems/leaves, and root) were assayed for Salmonella by plating onto Tryptic Soy Agar and using the MPN method. Salmonella levels in the soil gradually decreased over time, and soil persistence was dependent on the initial inoculation level. Salmonella levels were below the detection limit (< 100 CFU/g) in fruits and stems/leaves, regardless of the level of soil contamination. Moreover, S. Enteritidis-EGFP was not detected in the tomato fruits after root injury. These results indicate that the internalization of Salmonella in tomato fruits might not occur after cultivation in contaminated soil.

“…78 Despite the harsh conditions, produce are acting as a vehicle of salmonellosis in various foodborne outbreaks. [14][15][16][17][18][19][20][22][23][24][25][26][27][28][29][30] Another area of concern is that Salmonella spp are reaching contamination levels capable of causing illness. The typical infectious dose of Salmonella spp ranges from 10 6 to 10 8 CFU.…”
