This is a by product of beef production so they would be thrown away otherwise. There is a reason the bovine ovary used come from cattle from Argentina and New Zealand depending on what sort you buy. That is because they are grass fed not pumped full of growth hormone.

If you eat beef you are just as culpable imo!

Note that US cattle are not used as they are pumped full of growth hormone despite the major brands of BO being US brands. To be honest the welfare standards in Argentina and New Zealand are probably higher anyway too.
