Yes saris, I jump on any opportunity to get pastured pig organs, including heart, liver and brain, or anything else they'll give me!
It's all about how the animal is raised. If you took these same animals that I buy pastured, and instead raised them in a cage, not big enough to move around, pumped them full of antibiotics and hormones and fed them only corn, soy and minerals, I wouldn't touch them with a ten foot pole! Same for poultry, zebras, giraffe or hippopotamus!
