Milk Samples

Purpose – Current study was carried to detect the presence of pathogenic bacteria including the drug-resistant ones from milk and milk products. The paper aims to discuss these issues. Design/methodology/approach – Twenty-six raw milk samples from ten different areas, 28 pasteurized milk samples from 12 different companies and 26 yogurt samples from ten different sources in Dhaka city were microbiologically analyzed through cultural and biochemical identification of the isolates. Drug resistance trait was also determined by the Kirby-Bauer method on Muller-Hinton agar. Findings – Out of 80 samples studied, 74 were found to harbor pathogens within a range of 102-104 cfu/ml, including Escherichia coli, Salmonella spp., Staphylococcus aureus, and Vibrio spp. The study of antibiogram revealed that most of the isolates were resistant against most of the commonly used antibiotics. Research limitations/implications – Employment of only cultural/ biochemical tests excluding the molecular detection of virulence and/or antibiotic resistance genes might stand as a shortfall of the study. Nevertheless, such basic approach of microbiology can make this type of study replicable in the resource poor settings in the other developing countries. Practical implications – Routine detection of drug-resistant bacteria can further unveil the complications in chemotherapy during the endemic food borne diseases. Social implications – The study outcome/knowledge would aid to a better public health management especially in the developing countries. Originality/value – The presence of drug-resistant pathogenic bacteria in most of the tested milk samples poses a great public health threat, especially to the children. Therefore, the study revealed the necessity of maintaining proper hygienic practice and care in handling and processing of milk and milk products.

Brucellosis continues to be a serious infection to human and animal populations in developing countries with detrimental impacts on public health and food animal production. This work aimed to estimate the prevalence of brucellosis in sheep and goats’ raw milk samples at Kirkuk Governorate, Iraq by identifying anti-Brucella antibodies and isolation of Brucella species. A total of 430 raw milk samples (210 sheep milk and 220 goats’ milk) were randomly collected from dairy females during the period from July to December 2019. The results showed an overall prevalence of Brucella antibodies in 12.3% and 10.7% of animals according to MRT and indirect ELISA, respectively. The overall isolation of Brucella species from raw milk samples was 10.0%. The isolated species of Brucella were B. abortus (37.2%) and B. melitensis (62.8%). An observable increase in occurrence during autumn (September to November) was detected, while autumn progress was associated with declining in brucellosis. In conclusion, brucellosis is still a significant public health hazard in Kirkuk Governorate. Based on test performance, the study recommends MRT as a rapid screening test for detecting brucellosis in milk in farms, centres, and dairy factories. Consumers are also recommended to sufficiently pasteurize the milk in order to kill this milk-borne pathogen before consumption.

Abstract Objective: This study aimed to evaluate the contamination rate of raw milk to Y. enterocolitica and biotyping of isolated organisms. Results: The results showed 33% of raw milk samples were contaminated with Yersinia enterocolitica. 1A biotype was the predominant one (26%) but two pathogenic biotypes including 1B (6%) and 5 (1%) were also detected. Isolation of potentially pathogenic Y. enterocolitica from raw milk and consequently its presence in dairy products which are made from raw milk is a public health hazard.

Methods Of Analysis

Milk and milk products containing penicillin may present a health hazard to individuals who are hypersensitized to penicillin. The following aspects of this problem are discussed: (a) the condition of human hypersensitivity to penicillin, (b) the mechanism by which milk may become adulterated with penicillin, (c) tolerances for residues of penicillin in foods, (d) methods of analysis and criteria of acceptance, (e) use of products containing penicillin, and (f) surveillance of products offered at import.

The re-emergence of tuberculosis (TB) has been observed in both developing and developed countries in recent years. Tuberculosis, a major public health and zoonotic problem, is responsible for 2 to 3 million human deaths annually (WHO 2003) and also causes great economic loss in the animal industry. Tuberculosis has been declared a global emergency by WHO in 1993; the first to be declared as such. Nigeria with a population of over 120 million people and cattle population of about 19.8 million has been ranked 4th among the world’s 22 countries with a high TB burden. The objective of this study was to determine the prevalence of bovine tuberculosis among Fulani cattle, which are the main source of milk and milk products to the public. The culture of consuming raw milk as a local delicacy known as ‘fura da nono’ among Nigerians especially in the study area informed this study.

Aeromonas hydrophìla has been considered human pathogen and is involved in gastroenteritis, wound infections and septicaemia. It is also a cause of disease in fish, in amphibian and in reptiles. A. hydrophìla can grow in chilled foods and has been isolated from the environment, from non chlorinated and chlorinated water, ready-to-eat meat from poultry meat, fish and fish products, raw milk and milk products and vegetables. The present article is a review article and deals with the isolation and identification procedures, pathogenesis and epidemiology of the microorganism and the therapy to humans.

The present study was carried out to observe the presence of Salmonella in milk and milk products. The investigation of 210 samples revealed presence of 7.61% Salmonella spp. with higher prevalence in raw milk and dahi - 11.9% each , followed by ice-cream -9.52% and khoa - 4.76%. None of the sample of flavored milk showed Salmonella. In molecular study, 5 (31.2%) isolates were found positive for invA gene. The gene was present in raw milk - 18.75% and 6.25% in khoa and ice-cream each. Salmonella isolates were found sensitive to netillin - 100%, ofloxacin - 87.5%, norfloxacin, ciprofloxacin and nalidixic acid – (62.5% each), streptomycin and amikacin – (56.2% each). The isolates were resistant to nitrofurantoin- 81.2%, tetracycline -75.0%, co-trimoxazole - 68.7%, ampicilline - 56.2% and cefotaxime - 50.0%. The observation displayed unhygienic atmosphere prevailing during production of dairy products which lead to contamination of Salmonella and thus may cause public health problem to the consumers.
