UNLABELLED Bovine tuberculosis is an ongoing problem in Ireland, and herd incidence has remained at approximately 5% for some years. Spillover of infection from cattle to people remains an ever-present possibility, given the ongoing pool of infection in the Irish cattle population. This paper describes an outbreak of tuberculosis affecting cattle and people on a dairy farm in southeastern Irela...

Among recent trends towards less processed foods is a growing consumer demand for raw (unpasteurised) dairy products. In spite of the public health risks and an increased awareness of pathogens in milk, proponents of raw milk consumption are of the view that pasteurisation kills beneficial microorganisms believed to have antimicrobial properties towards pathogens. This study thus aimed to exami...

Brucella melitensis is the cause of brucellosis in sheep and goats, which often results in abortion. Few cases of B. melitensis infection in goats have occurred in the United States over the last 25 years. However, vigilance must be maintained, as it is for the bovine milk industry, to ensure that brucellosis is not introduced into the U.S. goat population. The objective of this study was to de...

Breast-feeding is the golden standard for infant feeding. However, the majority of a few week old infants are fed with a second choice infant feeding, cow's milk based formula. Amongst the multiple differences between human and cow's milk regards the development of the gastro-intestinal flora: the flora of the breast-fed infant being richer in bifidobacteria and lactobacilli. Both species are k...

CXC chemokine receptors 1 (CXCR1) play a key role in inflammatory response and eventual activation of the innate immunity. Mastitis is a big problem in dairy industry. In the presented study the bovine CXCR1 gene was considered a candidate gene of anti-mastitis defense in Chinese Holsteins. Polymorphism of bovine CXCR1 was investigated and its associations with Somatic Cell Scores (SCS) and mil...

despite the potential of high intensity ultrasound treatment on homogenization of milk and dairy based products, this treatment, under certain conditions, may lead to produce off-odors which can influence its applicability in the food industry. therefore, in this research, cacao flavored milk (chocolate milk) was treated using ultrasound at various levels of power intensity, exposure time, and ...

Mycobacterium avium ssp. paratuberculosis (MAP) infections cause major losses to the dairy industry. Transmission of MAP occurs primarily via feces and in utero, but MAP can also be excreted in colostrum and milk. The objective of this study was to determine whether colostrum and milk fed to calves are important risk factors for infection with MAP. A questionnaire was sent to 1,050 farms partic...

Antimicrobial usage in food animals has a direct impact on human health, and approximately 80% of the antibiotics prescribed in the dairy industry are used to treat bovine mastitis. Here we provide a longitudinal description of the changes in the microbiome of milk that are associated with mastitis and antimicrobial therapy. Next-generation sequencing, 16 S rRNA gene quantitative real-time PCR,...

The aim of the present study was to evaluate relationships between the presence of the two major bovine acute phase proteins haptoglobin (Hp) and serum amyloid A (SAA) and raw milk quality parameters in bulk tank milk samples. Hp and SAA have been suggested as specific markers of mastitis but recently also as markers for raw milk quality. Since mastitis has detrimental effects on milk quality, ...

This study investigated the levels of the antibiotic tetracycline contained in cow milk, goat milk, butterfat, soft cheese and yoghurt samples. High performance liquid chromatography (HPLC) standard methods were used for the detection and quantification of tetracycline in 40 dairy products samples. All the analysed samples contained residues of tetracycline antibiotics. The mean tetracycline re...
