Microbial counts in different tissues of carrots (<I>Daucus carota</I> L. <I>var sativ</I> DC.) were determined by varying their cultivation method (conventional, reduced-agrochemicals or organic), variety (European or Asian) and transportation period (distributed in the market or evaluated immediately after harvest). The microbial counts in all carrots were found to be in the order of epidermis>phloem>cambium≥xylem. In the epidermis, cambium and xylem, the organic products cultivated without agricultural chemicals resulted in the highest microbial population, and the conventional products in the lowest counts. The two variety did not show significant difference in the microbial counts of the four tissues. Carrots evaluated just after harvest at field showed lower microbial counts than those in the market.
