Summary

L. monocytogenes appears only in the rind (where the pH is greater than 6.3) and never grows in the core of the cheese. Under these conditions, a specific irradiation of the rind after ripening, with a low-energy electron beam at relatively high doses (up to 3 kilograys), allows the total elimination of L. monocytogenes in heavily contaminated samples (100.000-1 million CFU/g) without noticeable modifications of the organoleptic properties of the cheese.
