Although I see Marla's point, I have to agree with Don here.  If it doesn't have to do with keeping dairy or lactose free, then it really should be taken to another list.  Not to mention that I think she would have more luck asking that question of people with environmental allergies.  It didn't bother me that she posted, I'm just saying that Don is right here.  Sorry Marla, please don't take offense because I always get so much from your posts!  Debby
