Unpasteurized artisanal cheeses are a source of pathogens for humans. We isolated lactic acid bacteria (LAB) from raw milk and from cheeses made with raw milk, and formulate starter cultures for producing an artisanal Mexican cheese known as ‘Queso Bola de Ocosingo’. We evaluated six combinations of strains as starter culture-treatments. The proximate composition of the cheeses, the sensorial evaluation, and the microbiological safety of cheeses made with pasteurized milk was evaluated. The use of starter culture helped to maintain the pathogen microbial total count of pasteurized cheese below the standard limit maximums. The sensory judges did not find differences among the cheese elaborated with unpasteurized milk and that elaborated with pasteurized milk and the starter culture added. The starter culture formulated with LAB derived from unpasteurized cheese can be used for producing ‘Bola de Ocosingo’ cheese which is sensory acceptable and microbiological safe.
