Aflatoxin M1 (AFM1) contamination in milk and milk products may pose a major public health concern. The present cross-sectional study was aimed to estimate the prevalence of AFM1 in bovine milk across all districts of Punjab, India and to identify the associated animal and farm level risk factors. A total of 402 milk samples (266 cow milk and 136 buffalo milk) were analysed using commercial ELISA and representative samples were confirmed using HPLC-FLD. The results revealed that 56.2 and 13.4% of the milk samples exceeded the maximum levels of the European Union, i.e. 0.05 μg/l and Food Safety and Standards Authority of India (FSSAI), i.e. 0.5 μg/l for AFM1 in milk, respectively. On analysis of species variation, buffalo milk (prevalence: 56.6%; mean concentration: 0.42±0.9 μg/l) was found to have higher AFM1 levels than cow milk (prevalence: 56.0%; mean concentration: 0.19±0.3 μg/l), with statistically significant difference between mean concentrations (P<0.01) and non-significant difference between AFM1 prevalence (P=0.91). Furthermore, milk from commercial dairy farms (prevalence: 64.7%; mean concentration: 0.34±0.65 μg/l) was found to be more contaminated than from household dairy establishments (prevalence: 47.8%; mean concentration: 0.19±0.65 μg/l). The risk factors ‘above average milk yield/day’ (odds ratio (OR): 2.4) and ‘poor animal hygiene’ (OR: 1.9) were identified at animal level, and ‘intensive dairy farming’ (OR: 3.1) and ‘animal feed without aflatoxin binder’ (OR: 4.7) as farm level risk factors for AFM1 excretion above maximum levels of European Union in milk. Among cow breeds, the milk from ‘non-descript’ breed (OR: 11.5) was found to be most contaminated with AFM1 and the least from Jersey breed (OR: 1.0). The present study highlighted the presence of AFM1 in milk samples; therefore, regular monitoring of AFM1 in milk is required so that high risk regions and associated risk factors can be addressed appropriately.

Associated Risk Factors

Q fever is a zoonotic disease caused by the rickettsia-like Coxiella burnetii and leads to abortions and decreased reproductive performances in domestic ruminants. A serological survey, using ELISA test, was conducted to assess the prevalence of this infection in 226 ewes belonging to 39 flocks localized in Constantine (North-eastern Algeria). A pretested questionnaire has been submitted to farmers/shepherds to collect information related to relevant risk factors. Results revealed the presence of C. burnetii antibodies in 12.4% (95% CI: 8.08%−16.72%) of individual animals while 35.9% (95% CI: 21.20%−52.82%) of sampled flocks accounted at least one seropositive ewe. Significant causative associations were observed for origin of animals (χ2=14.29, P=0.001), vaccination against enterotoxaemia (χ2=12.12, P=0.002) and pox (χ2=5.30, P=0.025), access to the farm by foreign visitors (χ2=10.87, P=0.004), farmers/shepherds’ visits to other farms (χ2=6.31, P=0.021), disinfection frequency (χ2=7.98, P=0.046), pest infestation within farms (χ2=9.55, P=0.049) and abortion history (χ2=5.54, P=0.029). This recorded prevalence of Coxiella infection would indicate a possible responsibility of this agent in causing abortion and reproductive failures in the tested flocks. Implementing active surveillance programs and further investigations using more accurate analyses and including large samples of more animal species from several provinces are needed to eluci date the real occurrence and dynamics of this infection in the national livestock.

Mastitis is one of the most economically important diseases in dairy farms worldwide. It is particularly important in Ethiopia where no routine prevention and control practices are in place. This cross-sectional study was carried out between October 2017 and June 2018 to estimate the prevalence of mastitis, identify the associated risk factors and isolate bacterial causes in dairy farms located in southern Ethiopia using standard microbiological methods and questionnaire survey. A total of 686 lactating cows which were found in 122 selected dairy farms were investigated by physical examination and California mastitis test. The overall cow-level prevalence of mastitis was 54.2% (95% CI: 50.5 – 57.9%). Based on the study site, the prevalence was 55.7% in Hawassa, 54.3% in Arsi Negele, 52.6% each in Wondo Genet and Wolayta Soddo towns with no significant (p > 0.05) difference among the sites. The majority of mastitis cases were subclinical (48.1%) while the clinical mastitis was only 6.1%. Of the 122 herds tested, 109 (89.3%; 95% CI: 82.1 – 93.9%) had at least a cow positive for mastitis. The study showed that high parity number (OR = 1.6; p = 0.015), flat (OR = 4.5; p <0.001) and round (OR = 2; p <0.001) teat end shape, history of mastitis in preceding lactation (OR = 3.3; p <0.001), and slightly (OR = 3.5; p < 0.001), moderately (OR = 4.9; p < 0.001), and very dirty (OR = 9.2; p < 0.001) udder and legs were the major risk factors which are significantly associated with higher prevalence of mastitis. Based on the available media and reagents, the major bacteria isolated from subclinical mastitic milk samples were Staphylococcus spp. (57.3%), Streptococcus spp. (18.6%), E. coli (17.3%) and Bacillus spp. (7.5%) in order of their abundance. The present study revealed a high prevalence of mastitis, particularly the subclinical one, and the associated risk factors. Enhancing the awareness of dairy farmers, regular screening of cows for subclinical mastitis, proper treatment of the clinical cases, improving the hygienic condition of the cows, and culling of chronically infected cows are critically important to prevent and control bovine mastitis.

Abstract Background Cross-sectional study was conducted from June 2017 to January 2018 with the objective of determining the prevalence of mastitis and identify the associated risk factors in and around Bahir dar dairy farms. Totally 302 lactating cows were selected using simple random sampling method. Initially, mastitis cases were diagnosed based on California Mastitis Test (MCT) results and the nature of gel formation. Then positive samples were subjected to bacterial culture and isolation using blood agar, MacConkey agar, colony morphology, Gram stain, and biochemical tests. Statistical analysis was carried out using STATA software and association of mastitis with risk factors was analyzed using chi square test. The association was considered as significant when p-value was less than 0.05. Result The overall cow level prevalence of mastitis using CMT was 25.16% (76/302) with clinical and sub clinical mastitis of 3.64% and 21.52%, respectively. Similarly, the quarter level mastitis was 10.43% (126/1208) with clinical and sub clinical cases of 1.49% and 8.94%, respectively. Bacteria identified were Staphylococci Spp, Escherichia coli, Bacillus Spp, and Streptococcus Spp. with a proportion of 66.07% .94%, 8.0% and 7.14%, respectively. Body condition score, cow Hygiene, Parity, history of mastitis, stage of lactation, teat lesion, use of same clothing, lactating mastitis positive animal last were found to be significant risk factors. Conclusion The current study revealed moderate prevalence of mastitis warranting application of appropriate hygienic practices during milking and awareness creation to the dairy farmers.
