Unlike cow milk, which has stringent hygiene and safety regulations, microbiological standards for the production and distribution of goat milk is more relaxed. Whilst most of the consumer prefer to drink raw goat milk due to their belief in some benefits of it, so far this product has less attention in terms of quality and safety control from government authority as compared to cow milk and milk products. Therefore the investigation on the microbiological quality of raw goat milk and its associated risk factors is of central importance. This book provides integrated approach of analysis by evaluating the relationship between animal and farm conditions and microbiological quality of its product. The methods of analysis are simple and applicable, it can be used by anyone who have interest in the field of animal food hygiene and safety. The baseline information from this study can also be used by authority in formulating intervention policy to assist the farmers for improving their systems of keeping animals and the quality and safety of the products.

Reliability of quality of milk produced by smallholder farmers was assessed by means of a comparative analysis of the microbiological quality and somatic cell counts (SCC) of the raw milk obtained from dairy goats. Information regarding dairy goat farming and goat milk production in and around Pretoria was initially determined by means of a questionnaire. With this information, dairy goat herds were selected for the study, based on the fact that these farms produced milk for both domestic and commercial consumption. The study was conducted on three commercial dairy goat farms each under a different production system, the extensive, semi-intensive and intensive production systems. The method of milking varied with the type of production system; hand milking, bucket system and pipeline milking respectively. Udder health under the respective production systems was assessed by means of bacterial analysis of udder half milk samples. Bacteriology of bulk milk samples was also determined in order to assess the level of hygiene in the milking environment. In addition, water samples from the different farms were analysed for their microbial quality. Results of these parameters were compared between the different production systems using the analysis of variance. Capability of safe raw milk production by smallholder dairy goat farmers was then evaluated from the results obtained. Reliability of the SCC as a reflection of goat udder health was also evaluated. Further assessment was carried out to determine the relationship between udder conformation and presence of intra-mammary infection and SCC of the raw milk. Bacteria potentially capable of producing either food poisoning or enhanced spoilage of raw milk were cultured from the goat milk samples. These included pathogens such as Staphylococcus aureus, Bacillus cereus and Enterococcus faecalis, found associated with use of milking machines as was the case in the intensive and semi-intensive production systems compared to the extensive production system. The prevalence of intramammary infection was 33.3%. Coagulase negative staphylococci were the most common cause of intramammary infection with a prevalence of 86.6% of the infected udder halves. They includedStaphylococcus epidermidis, Staphylococcus simulans and Staphylococcus intermedius. The remaining 13.4% of the infection was due to Staphylococcus aureus. Somatic Cell Counts were not a reflection of udder health status, hence, not reliable in the prediction of goat udder health (p = 0.2 Fisher’s exact test of association). No significant relationship was proved to exist between the udder conformation and presence of intra-mammary infection or SCC of the milk produced. Raw milk obtained by the bucket system milking machine had the lowest total bacterial count (TBC) (16 450 Colony Forming Units per millilitre [CFU/ml]) as compared to that by pipeline milking machine (36 300 CFU/ml) or hand milking (48 000 CFU/ml). In comparison to the other two production systems, it was shown that dairy goat farming under the extensive production system, where hand milking was practised, was adequate for production of safe raw goat milk. Coliforms were found to be the most predominantly isolated organisms from the raw milk obtained under the extensive production system. However, these can be eliminated by pasteurisation of the milk. The extensive production system, therefore, could be a means to promote dairy farming in developing communities through smallholder farmers. This could be facilitated by extension services aimed at monitoring management on the farms. This would, consequently, help alleviate the problem of food security and low income in these communities.

The microbiological quality of traditional homemade cheeses and their safety for consumers depends on the microbiological quality of the raw milk used for production, compliance with environmental hygiene standards, the selection of the right disinfectant as well as workers and their personal hygiene. In case of non-compliance with hygiene standards, microbial contamination of raw milk and milk products may occur. Activity of microorganisms can affect health safety and milk technological processing. Undesirable microbiota of milk include frequently present enterobacteria of the genera Escherichia and Enterobacter (Escherichia coli, Enterobacter aerogenes). A serious risk is also associated with resistant microorganisms and their resistance to more than one antibiotic. Among them we also include bacteria of the genus Staphylococcus sp., which are the main causative agent of mastitis, with higher prevalence in cases of clinical and subclinical manifestations. Recently, the production of enterotoxins has been also confirmed in the aforementioned genus of staphylococci.the presence of enterotoxigenic isolates indicates a potential risk of staphylococcal enterotoxicosis in humans.Based on the above facts a more extensive study about microbiological quality of selected dairy products with a focus on the detection of resistant microbiota is needed, the presence of which creates the possibility of spreading antimicrobial resistance through the food chain.

Raw milk sales are legal in 30 states, including Mississippi, where regulations are largely management-based and not food-safety related. The research objectives were to analyze the microbial profile of raw goat milk from Mississippi farms and assess food safety practices and perceptions of dairy goat farmers. Deficiencies and opportunities for improvement in raw goat milk safety were identified. Staphylococcus spp. was present in most (70%) milk samples but aligned with drying-off. E. coli, Enterobacteriaceae, and coliforms were observed in 4, 10, and 12 samples, respectively; no Salmonella spp. or Listeria monocytogenes were detected. The survey highlighted farmers' need for educational opportunities on safe milk handling with emphasis on handwashing. Most producers (80.8%) are willing to invest more in their farms, creating strategic opportunities for extension outreach to help with market expansion and sustainability. Overall, training accessibility could help producers nationwide by encouraging safe milk handling and best management practices.

Food safety regulators face a daunting task: crafting food safety performance standards and systems that continue in the tradition of using the best available science to protect the health of the American public, while working within an increasingly antiquated and fragmented regulatory framework. Current food safety standards have been set over a period of years and under diverse circumstances, based on a host of scientific, legal, and practical constraints. Scientific Criteria to Ensure Safe Food lays the groundwork for creating new regulations that are consistent, reliable, and ensure the best protection for the health of American consumers. This book addresses the biggest concerns in food safetyâ€"including microbial disease surveillance plans, tools for establishing food safety criteria, and issues specific to meat, dairy, poultry, seafood, and produce. It provides a candid analysis of the problems with the current system, and outlines the major components of the task at hand: creating workable, streamlined food safety standards and practices.

Goat science covers quite a wide range and varieties of topics, from genetics and breeding, via nutrition, production systems, reproduction, milk and meat production, animal health and parasitism, etc., up to the effects of goat products on human health. In this book, several parts of them are presented within 18 different chapters. Molecular genetics and genetic improvement of goats are the new approaches of goat development. Several factors affect the passage rate of digesta in goats, but for diet properties, goats are similar to other ruminants. Iodine deficiency in goats could be dangerous. Assisted reproduction techniques have similar importance in goats like in other ruminants. Milk and meat production traits of goats are almost equally important and have significant positive impacts on human health. Many factors affect the health of goats, heat stress being of increasing importance. Production systems could modify all of the abovementioned characteristics of goats.
