The Safe Dairy Campaign to Greet the World Exposition, which had lasted for a whole year, escalated on March 13 when it has decided that this year Shanghai will implement key monitoring of the source of milk produced locally to gradually improve the quality of the milk for sale. Currently, Shanghai has moved a step forward from collecting milk from individual cow farmers to achieving a scale production of milk. It is learned that Shanghai used to have over 1,000 individual cow farmers, but now has realized a moderate degree of scale operation. The number of cows registered in over 100 cow farms all exceeds 100.
