California Mastitis Test

Improvement of traditional and nomadic milk production through dairy development program in Nigeria requires routine quality and safety monitoring of milk both at herd level and milk collection centers. A total of 411 bulk raw milk samples aseptically obtained from Ibarapa, Oyo and Oke-Ogun industrial milk collection centers were subjected to California Mastitis Test (CMT), Bulk Somatic Cell Count (BSCC) and bacteriological analysis for assessment of quality and safety of milk from the herds. One hundred and seven (26.0%) of the samples were CMT positive, while 74.0% were negative to CMT. The overall mean BSCC, TAC and TCC were 1.27×103 ± cells/mL, 1.12×103± 34 cfu/mL, 97.8±9.8 cfu/mL in the CMT negative milk samples while for the strong positive samples the mean BSCC, TAC and TCC were 4.33×106 ± cells/mL, 2.35×106 ± 453 cfu/mL, 189.3±41.1 cfu/mL respectively; these were higher than the Pasteurized Milk Ordinance acceptable limits. Positive correlation was found between CMT scores and bacterial contamination and between CMT scores and SCC was recorded. About 26.0% of the samples with positive CMT could be considered unsafe due to strong correlation with microbial contamination that could result in milk borne zoonoses and public health hazards. However, a greater proportion (76.9%) of the milk with negative CMT scores could be safe for human consumption after post-harvest pasteurization. Consequently, there is need to improve handling, environmental and milking hygiene; as well as proper herd and udder health management to improve quality and safety of Nigeria dairy products.

Cheese Production

The serrano artisan cheese produced from raw milk of dairy cattle is a typical product of high-altitude farms in the states of Santa Catarina and Rio Grande do Sul. However, marketing of the cheeses occurs illegally because they lack the minimum maturation period required for cheese produced from raw milk. The production of artisan cheeses is required to follow strict hygiene standards. This study aimed to test the quality and safety of cheeses that were produced in 31 farms of the Serrana region in Santa Catarina after 14 and 28 days of maturation. Coliform count was measured at 35 °C, and presence of other microorganisms such as Escherichia coli, Staphylococcus, Listeria spp., and Salmonella spp. were also tested. Fat and protein percentages, acidity, salt content, and humidity were also evaluated. Data were subjected to statistical analyses using the SAS® software. After 14 and 28 days of maturation, 74.19% (23/31) and 64.52% (20/31) of samples, respectively, showed higher numbers of coliforms at 35 °C than those permissible by law. Higher than permissible numbers of E. coli were observed in 45.16% (14/31) and 48.39% (15/31) of the samples analyzed after 14 and 28 days of maturation, respectively. Coagulase-positive staphylococci values above 103 CFU/g were observed in 54.84% (17/31) and 51.61% (16/31) of cheese samples after 14 and 28 days of maturation, respectively. Contamination with Salmonella spp. was not detected. However, Listeria monocytogenes serovar 4b was isolated in 3.23% (1/31) and 6.45% (2/31) of samples after 14 and 28 days of maturation, respectively. The results of humidity tests classified the cheese samples into three categories: low, medium, and high humidity. Semi fat cheeses were predominant in both maturation periods, although the samples were classified in thin, semi fat, and fat cheeses. The main variations in the compositions of analyzed samples occurred for salt and acidity levels. The maturation process has not proven to be effective in reducing microbiological contamination to compliance levels. Considering the heterogeneity of the analyzed cheese samples, the frequency of non-conformities with respect to microorganisms and pathogens present in the samples, this study indicates the necessity to improve the Serrano artisan cheese production system through adoption of good manufacturing practice measures.

Quality Of Milk

The most pressing problems of the food industry today are the quality of food. The main factors influencing this indicator are the quality of raw materials, the technical and technological level of enterprises, the quality management system and food safety. Milk quality cannot be improved in the processing process, at best it can be stabilized, so the milk quality management system should focus on the technological processes of its production and primary treatment using a preventive approach. The sanitary and hygienic quality of milk production is a complex problem that is determined by a number of factors that combine the notion of "technology and culture of production". General bacterial contamination of milk raw materials should be considered as a collection of sources of ingress of microorganisms into the technological environment, in particular the microflora of the surface of the udder and lobes; microflora of udder channels; microorganisms of milking equipment, milk lines, milk packaging; microflora of personnel and environment. The traditional scheme of primary milk treatment provides a consistent picture of the quality and safety of raw milk obtained from its production. Measures to improve the quality and safety of raw milk through additional use of the decontamination process are proposed. The use of ultrasonic cavitation technologies for milk disinfection allows to increase the quality of milk and to get more money for the farm, to provide quality raw materials for dairy enterprises.

The aim of this review is to overview important literature data on milk and its composition, methodology of quality assurance throughout its processing and preservation, and to compare risks and benefits of consuming raw (unpackaged) and pasteurized (packaged) milk. Milk contamination risks are of various types, including physical contamination (foreign components, such as manure, feed, dust, pieces of broken glass, strands of hair, wood, plastic, or metal chips), chemical impurities (antibiotics, hormones, pesticides, detergents, or heavy metal residues), and microbiological agents (germs and somatic cells). Our study addresses the quality and safety of raw and pasteurized milk consumed by humans. If one considers risks and benefits simultaneously, there are many pros and cons of consuming raw and pasteurized milk. One can conclude that pasteurized milk is more appropriate for consumption as compared to the lower quality raw milk. For manufacturing high quality pasteurized milk, one should implement good hygienic practices, proper pasteurization process, as well as pre and post pasteurization preservation.

ABSTRACT: Moderate and high humidity cheeses are described as important vehicles of pathogens in many foodborne diseases outbreaks. Microbial contamination can occur in raw material or in the different steps of the product processing due to inadequate hygiene practices. Thus, the aim of this study was to evaluate the microbiological quality and safety in the production of moderate and high humidity cheese. Samples from raw milk, handlers’ hands surface, final product were collected in three cheese manufacturing plants located in southern Brazil, with different levels of sanitary control. Effectiveness of milk pasteurization was also evaluated. Thermotolerant coliforms, coagulase-positive staphylococci (CPS), Salmonella spp., and Listeria monocytogenes were evaluated. Raw milk samples showed the highest contamination levels, with enumeration of 1.1x105 most probable number (MPN) mL-1 for thermotolerant coliforms, 4x105 colony-forming units (CFU) mL-1 for CPS and presence of Salmonella spp. CPS were also reported in one sample of handler’s hands surface. However, only one sample of the final product was out of Brazilian regulatory standards, exceeding the limit allowed for CPS. Milk pasteurization process used in cheese preparation was effective, regardless the level of sanitary control of the industries. Results highlighted the need for better hygiene practices, in obtaining the raw milk and in the handling during the cheese manufacturing steps.
