Title: Knowledge and Application of Good Hygienic Practices in Dairy Farms Sharq Alneil Locality Khartoum North 2015
Author: Mahmoud, Namariq Mahmoud El Hassan
Abstract: Background: Milk is considered as a highly perishable food and must be collected, stored and processed under the best hygienic conditions, because poor hygienic practices and poorly preserved milk can cause infections, food poisoning and economic losses. The objective of this study was to investigate the status of knowledge and application of good hygienic practices in 70 dairy farms at Sharq Alneil locality, Khartoum North (40 farms from Helat Kuku and 30 farms from Alselat). Methodology: This was a cross sectional study, milk samples were collected from systematically selected dairy farms at Khartoum North. Information about dairy management was collected by questionnaire and direct interview with the selected farms' owners. Some laboratory tests were also done for milk samples to determine the hygiene and quality of raw milk by estimation the total bacteria and coliform counts and detection of yeast and moulds. Results: Only 2.9% of workers received training on good dairy practices and 65.7% were hired labours. Moreover 52.9% of workers do not come to work if they were sick and 57.1% washed their hands with detergents before starting the work. The majority of farms (72.1%). were specialized farms (for milk production only) Most of these farms were not satisfactory and poorly constructed and had limited management skills. The unavailability of water, feed and season were found as the main reasons for reducing milk production. The dairy owners who kept records of their farms were 7.1% only. Vaccination against diseases was rarely used in a regular way. General hygiene and sanitation measures such as disinfection, routine cleaning programs and maintaining minimal contamination during milking was not found in many of these dairy farms. There was few differences between the dairy farms located at Alselat area and Helat Kuku in many aspects such as number of milkers who do not practice milking when they were sick (70% in Alselat and only 40% in Helat Kuku), however the availability of hot water was found in about 13.3% dairy farms in Alselat and 57.5% dairy farms in Helat Kuku. Also the numbers of dairy farmers who use the plastic containers are 16.5% in Alselat compared to only 2.5% in Helat Kuku. The dairy farmers who practiced post milking teats disinfection were 6.7% in Alselat and 32.5% in Helat Kuku and generally the overall status of dairy farms was good in 50% of Alselat dairy farms and 77.5% of Helat Kuku dairy farms. The laboratory tests showed that the total plate count exceeded the limits according to (KeBS) legislations in 14.5% of the raw milk samples taken from the farms under study, and about 18.6% of raw milk samples were highly contaminated with coliform bacteria, moreover yeasts and molds were also found. Conclusion: The present study concluded that the results found might create health risk and environmental contaminations. Recommendation: This study recommended further studies on the application of good hygienic practices in this area, and to draw the attention of the researchers and the professionals in the ministries concerned on the importance of well educated and trained workers and dairy farms owners in order to raises the production level and it is quality.
