Milk is sterile as it is synthesized in a healthy mammary gland.

Explanation:
Milk produced by a healthy mammary gland is sterile at the moment of secretion. The secretory cells release milk free of bacteria, and the udder’s defenses help keep it that way. Bacteria can enter milk later, during milking or handling, through the teat canal or contaminated equipment, or if the cow has an infection like mastitis. That’s why, even though the milk starts off sterile, pasteurization is essential to kill any pathogens that might have entered after secretion. So the statement is true: milk is sterile as it is synthesized in a healthy mammary gland.
