Can you develop an allergen to red meat?

I have been having stomach issues lately where I either vomit or have diahreah. My dr has chalked it up to my acid reflux and I have went with that diagnosis for awhile now. I recently went back home and we ate a lot of red meat and my stomach was upset the entire two weeks that I was there and it was worse on days that we ate red meat. I grew up on a farm and we always ate red meat and I have never had problems until recently. My husband and I don't eat a lot of red meat so with my stomach being upset the entire time I was at my parents house I was wondering if I could be developing an allergy to red meat.
