• D. C, D, and E

Hint:

Differentiate between "personal hygiene" (related directly to the body and health of the milker) and "environmental sanitation" (manure disposal, barn cleaning) to solve hygiene-related questions.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Clean milk production depends heavily on the hygiene of the milking environment, the animal, and the milker.
"Personnel hygienic practices" refer specifically to the physical hygiene, health status, and direct actions of the human handler (milker) during the milking process.

Step 2: Detailed Explanation:
Let us categorize the given practices:
- A. Free from infectious diseases: This is a critical personnel health requirement to prevent the transmission of zoonotic pathogens or human pathogens (e.g., typhoid, tuberculosis) into the milk supply. (True)
- B. Hands to be cleaned with soap and water before milking: This is a direct personal sanitary action to eliminate transient pathogens on the milker's hands before touching the udder or milking utensils. (True)
- C. Nails to be cut regularly: Long nails can harbor dirt, manure, and bacteria, and may also injure the cow's teats during hand milking. Maintaining trimmed nails is a personnel requirement. (True)
- D. Efficient disposal of manure and waste: While important for overall barn sanitation, this is an environmental management practice rather than a direct personal hygienic practice of the milker. (False)
- E. Clean Milking Competitions for milkers: This is an educational or promotional event designed to encourage good habits, not a daily personnel hygienic practice itself. (False)
Therefore, the relevant daily personal hygienic practices are represented by A, B, and C.

Step 3: Final Answer
The correct option is (A).
