It could have just been seasoned differently or something. I've eaten chicken and stuff before that tasted weird to me but was fine. If you didn't eat much of it then it should be fine. Was your parents sausage fromt he same package? It is possible it was seasoned differently or even when you cooked it it could have gotten more of the seasoning or veggies or soemthing in it.
