Popis: Samples of artisanal Chihuahua cheese were collected in autumn, winter and summer from five farms from Chihuahua State, Mexico; temperature, pH and processing times were also recorded. Indicator microorganisms as well as lactic acid bacteria were determined. Samples were negative for Salmonella sp., and, except for coliforms, the particular season had a strong effect on counts of all microorganisms (4.8–6.0 log10 cfu/mL Staphylococcus aureus; 6.3–7.3 log10 cfu/mL presumptive Lactococcus sp; 7.3–8.0 log10 cfu/mL presumptive mesophilic lactobacilli), as well as on processing conditions. The information presented is aimed to characterise Chihuahua cheese as a traditional product.
