Abstract

Campylobacter jejuni has been well studied and documented in its relation to poultry in nearly every aspect of growth to virulence to environmental susceptibility. Most recently, within the past decade or so, C. jejuni along with some other Campylobacter species have been investigated as to their ability to form biofims along various surfaces in aquatic environments. As in poultry studies, its virulence, growth, and suceptibility have also been documented as well as genetic factors inducing various protein production in response to such conditions. However, the incidence and viability of C. jejuni within vegetables is poorly understood. Due to most vegetables eaten in raw form, any infection stemming from such consumption is considered to be a result of cross contamination. Incidentally, reports have surfaced whereas clinical cases have been observed and reported with the claim of no possibility of cross contamination with meat. Increasing numbers of these reports prompted a limited number of studies that found C. jejuni in the soil of crops, mainly due to infected fertilization, as well as the surfaces of improperly washed vegetables not associated with cross contamination. The end results of these few studies have left open the possibility of vegetables that enter our markets with C. jejuni is due to either cross contamination with infected meats, contaminated soil adhering to the vegetables, or even inoculation into the vegetables via root systems. The later possibility has yet to be investigated in any significant manner. This study will help to bridge the gap fo the possibility of vegetable crop internalization due to soil contamination of C. jejuni, demonstrating this as a potential source of foodborne illnesses.
