Here's a guide to identifying them and avoiding bites She has diagnosed AGS in people who experience abdominal pain, diarrhea, nausea or vomiting about 2 to 6 hours after eating red meat. McGill has co-authored new guidance for the American Gastroenterological Association to raise awareness about the GI-only onset.

McGill says some alpha-gal syndrome, or AGS, patients feel sick to their stomachs after they eat red meat, but never develop more typical allergic symptoms, such as a rash, swelling or trouble breathing.

Scientists first connected the dots between red meat allergies and tick bites more than a decade ago, when they identified patients who got allergic reactions such as hives or anaphylaxis after eating beef or pork. And, there's another emerging risk linked to tick bites known as alpha-gal syndrome, which causes a red meat allergy.
