Hi JoAnn, They may >include diarrhea alternating with constipation, nausea, abdominal swelling, >pain and cramping. Complications can endanger the bladder, uterus and small >intestines. I am only theorizing, but these symptoms sound what I got from grain fed meats. Once I began eating grassfed beef, the symptoms went away. I think many people believe they are allergic to beef when it is the grains that are affecting them... What do you think? All the best, Susan
