Semi-hard cheeses were experimentally elaborated with pasteurized milk from sheep, goat and cow (15: 35: 50) and inoculated to contain 1.9 times 105Listeria monocytogenes/ml in cheeses 1 and 2 and 4 times 103L. monocytogenes/ml in cheeses 3 and 4. Counts of L. monocytogenes were determined by direct surface plating of samples on listeria selective agar medium. The results show the substantial survival of L. monocytogenes present in milk during manufacture and ripening of this type of cheese.
