                                As a direct response to customer feedback, Kroger transitioned its entire store-brand milk supply to be certified rbST-free by early 2008, a policy that remains in effect today. This means you can be confident that Kroger's private-label milk does not contain the controversial artificial growth hormone, though they are legally required to note that the FDA states no significant difference has been shown.
