Last year I bought half a calf from on of my buds a church.. had it killed aged and vacuum sealed.. and a local processor.. nice clean respected place.. the hamburger is wonderful.. but the steaks and roast have a "funky" smell when cooking and not so good a taste.. espically the fat.. if you get a bite with the fat..(which I love to eat) you have to spit it out.. I asked the processor about it and they said I had mis handled the vacuum sealed cuts..damaged the plastic.. and that the beef had taken on the freezer smell.. I was sceptical... So me and a cohort split another one last fall.. This time I got mine wrapped in freezer paper.. well so far.. we have only had a few roasts.. you can eat them..but man they have a un plesant smell.. I ask my bud about his and just the night before they cooked one in a crock pot and had to throw the whole thing out because of the smell... someone told me it was because they are finished on grass and not grain... does this make sense?..btw.. I have a cast iron stomach.. ive eaten coon and muskrat..
