"rbST-free" is on the label. But can you prove it?
Production claims like "rbST-free" now influence what consumers buy and what producers can charge. They also need scientific evidence to back such claims. The challenge is that recombinant bovine somatotropin looks almost identical to the growth hormone cattle produce naturally. Testing should therefore be both sensitive and highly selective.
A great read for anyone in dairy, food safety or analytical testing.
