Marks and Spencer has become the first major retailer to source its fresh milk from RSPCA Assured dairy farms.
All M&S fresh milk packaging will carry the RSPCA Assured logo*.
The RSPCA welfare standards for dairy cows have to be met for milk to be labelled RSPCA Assured.
The welfare standards cover cattle for their entire lives, including when being transported, and cover health, diet, environment and care.
