Just from the name you can envision Paul Bunyan and his ox Blue. These cows are built to be big, pumped up and prime. The cows originate in Belgium and have been genetically engineered. In the 2nd half of the 19th century, Shorthorn bulls from the United Kingdom were sent to Belgium to improve the muscle structure of the native cattle population.
If my dog won't eat genetically engineered food, and the birds that visit my bird house won't even touch genetically engineered seeds even during winter when food is scarce at best, I think it's only reasonable that it isn't safe for me to eat either.
Makes an interesting science experiment but nothing more.
