S. Sixty samples of raw goat milk intended for Caprino cheese-making were collected from ten farms in the Bergamo area over a 6-month period. Analyses of main microbial groups, somatic cell count (SCC) and pH were performed to determine the effect of origin (farm) and lactation period (April -September) on microbial composition and the incidence of pathogens in milk. Overall mean values were : standard plate count (SPC), 5n0i10% cfu\ml ; yeasts, 2n5i10# cfu\ml ; coliforms, 9n1i10# cfu\ml ; Escherichia coli, 2n9 cells\ml ; enterococci, 1n1i10# cfu\ ml ; lactococci, 3n4i10$ cfu\ml ; lactobacilli, 3n0i10$ cfu\ml ; halotolerant bacteria, 8n2i10$ cfu\ml ; spores of mesophilic aerobic bacteria, 11 cfu\ml ; SSC, 9n9i 10& cells\ml ; pH, 6n63. Moulds and spores of sulphite-reducing clostridia were found intermittently. Neither Salmonella spp. nor Listeria monocytogenes was detected, while Esch. coli O157 : H7 was isolated from one milk sample (an incidence of 1n7%). Staphylococcus aureus was discovered at a level 10# cfu\ml in 26 samples (43 %) with an overall mean of 1n2i10$ cfu\ml, whereas coagulase-negative staphylococci were found in 54 samples (90 %) with an overall mean of 1n3i10$ cfu\ml. Of Staph. aureus strains, 23 % proved to be enterotoxinogenic with a prevalence of enterotoxin C producers. Staph. caprae was the coagulase-negative species most frequently isolated ; none of the coagulase-negative staphylococci strains synthesized any of the enterotoxins tested for.Sample source was the major factor affecting the microbial composition of goat milk : significant differences ( P 0n01) were observed among samples from different farms for SPC, coliforms, lactococci, lactobacilli and halotolerant bacteria. Period of lactation had a significant effect ( P 0n025) on SCC and pH. SPC correlated well with coliforms, lactococci and lactobacilli ; SSC did not reveal positive interactions with any microbial groups or pH.K : goat milk, microflora, pathogens.Manufacture of dairy products from milk of small ruminants presents an opportunity to improve the economics of breeding and cheese-making in remote areas such as mountainous regions. Safeguarding and promoting traditional goat products has become part of a policy directed towards the protection of the
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
