Background: Food is the basic essential need for man. It contains a variety of nutrients, including carbs, proteins, fats, vitamins, and minerals. Milk is the main product of the dairy farm industry, and it is primarily produced for human consumption. Milk is ranked first among foods because it is an essential choice for humans from birth to senility. Milk born disease is a disease that is transmitted through contaminated milk and can be spread directly by humans or indirectly through air polluted water. It can come from any animal. Raw milk can carry dangerous germs such as Brucella, Campylobacter, Cryptosporidium, E. Coli, Listeria, and Salmonella. The most common sources of milk contamination are excrement from soiled animals, bacteria from poor milking practises, failure to detect milk mastitis pathogens, and foreign bodies, particularly from departed components from milking machines and bulk tanks used to transport milk.

Aim: The study was to evaluate the effectiveness of Video Assisted Teaching Programme regarding knowledge on milk borne diseases and milking practice among milk haulers in selected villages in Puducherry.

Methodology: Quantitative research approach was used. Pre-Experimental with one group pre-test and post-test research design was adopted to the study. Purposive sampling technique was used to select the samples. Pre-test was conducted to assess the level of knowledge by using the semi-structured questionnaires and observed practice by using checklist. On the same day Video Assisted Teaching Programme regarding knowledge on Milk Borne Diseases and milking practice. After seventh day of the intervention post test was conducted by using same semi-structured questionnaires and observed practice by checklist.

Result: The study scores revealed that the pre-test mean score of knowledge regarding milk borne diseases was 8.50±4.83 and the post-test mean score of knowledge was 14.60±1.43. The mean difference score was 6.10(30.5%). The calculated paired ‘t’ test value of t = 6.407 found to be statistically significant at p<0.0001 level. The study shows that the pre-test mean score of milking practice was 11.77±2.74 and the post-test mean score of milking practice was 14.37±1.16. The mean difference score was 2.60(13%). The calculated paired ‘t’ test value of t = 4.819 found to be statistically significant at p<0.0001 level.

Conclusion: The study result proved that the effectiveness of video assisted teaching among milk haulers had improved the level of knowledge on milk borne diseases and milking practice.
