No time to look for a link now, but the Cliff's Notes are: intensive farming methods used to produce chicken, eggs and pork (but rarely beef) are responsible for both increased resistance to antibiotics (along with their over-prescription to humans) and locally very intense concentrations of toxic pollution, especially in water. Cattle can be fed on grains, grass, or a combination, but chickens and pigs are virtually always fed grain, with all the environmental cost that entails.
The Tofu-BB burgers turned out great - same slightly-rare-beef taste as the Beyond Beef patties I mixed in, but less intense and with a texture I prefer. The smell remains a problem, though. Again, it isn't powerful but it's cloying and has staying power. EDIT: there is also a significant, although not strong, aftertaste that is also persistent. I may just try making tofu burgers with a little beet juice added, next time.
