Abstract The effect of manufacturing steps and storage in different modified atmosphere (MA) on L. monocytogenes in sucuk were studied. Sucuk dough was fermented for 3 days and ripened and dried with a stepwise RH and temperature reduction. The sucuks were packaged at different MA and stored at 4oC. After 3 days of fermentation, L. monocytogenes was decreased by 0.34 and 0.32 log cfu g-1 in sucuks made with and without starter culture respectively. The decrease was continued during ripening and storage periods at different MA. MA had significant (p
