This study examines the impact of traditional hygienic milking practices employed by rural small-scale dairy farmers on the quality of raw milk. While advancements in technology have revolutionized hygienic milk production methods for both small- and large-scale farmers, rural small-scale milk producers, particularly in countries like Zimbabwe, continue to rely heavily on hand milking as their primary method of milk harvesting. To investigate this issue, a convergent parallel mixed research approach was utilized, involving face-to-face interviews with 53 selected rural small-scale dairy farmers using a structured questionnaire. The collected data were analyzed using descriptive, frequency, chi-square, and cross-tabulation analyses. The findings revealed that participants aged 50 and above constituted the majority (58.5%) and were more likely to report low income. Additionally, households with 8 to 11 members (38%) and those with no formal education (18.9%) were also more likely to report low income. Several parameters were identified as significantly affecting milk quality (p < 0.05), including hand washing after milking, back leg tying, washing of milking utensils, use of towels, teat dipping, milking when sick, covering of milk, mixing of fresh and old milk, and lack of milk pasteurization before consumption. The study concludes that traditional hygiene practices contribute to milk contamination by rural small-scale dairy farmers, compromising the quality of raw milk. To support these farmers, interventions such as the provision of a dairy extension officer, practical workshops, incentives, entrepreneurial skills training, and farmer-to-farmer visits are recommended.
Background: Milk is one of the most nutritious foods providing a variety of proteins, fats, minerals, and vitamins needed to maintain, grow, and develop the body. The aim of this study was to assess microbial and chemical adulterants of raw cow milk collected from dairy farms of Hlabisa villages, KwaZulu-Natal Province, South Africa. Methods: A total of 68 raw cow milk samples were obtained from teats sampling points, milking buckets, and communal pooling buckets. The bacteriological analysis was conducted for the detection of various bacteria in milk samples. Biochemical tests were also done to detect some chemical adulterants in milk samples. Results: Total bacterial count of teats, milking buckets, and communal milk pooling buckets were 6.91, 6.06, and 6.06 log Colony Forming Unit (CFU)/ml, respectively. The most found chemical adulterant was urea detected in 23 out of 68 (33.8%) samples, followed by hydrogen peroxide showed in 22 out of 68 (32.3%) samples. However, none of the samples were contaminated with formalin, starch, and neutralizer. Conclusion: The present study revealed high microbial contamination of raw cow milk produced by rural small-scale dairy farmers of Hlabisa villages, KwaZulu-Natal Province, South Africa, indicating the lack of standard operating sanitation. It was also stated that raw milk samples contained various types of chemical adulterants that may lead to severe health problems. Good hygiene practices must be adopted by small-scale dairy farmers at every stage of their milk handling and processing.
