摘要: Raw milk from 70 farms was sampled over 13 months for salmonellas, listerias, Escherichia coli, Staphylococcus aureus and mastitic streptococci; total bacterial counts (TBC), coliforms and somatic cells were also counted. TBC≤ 30000/ml were obtained in 63% of samples. High count milks were found mainly during the winter months: 13% of samples had> 104 mastitis pathogens/ml of milk. The mean somatic cell count varied from 4.0× 105 to 8.0× 105/ml throughout the year with highest counts during the late lactation period. Coliforms …
