This is happening. Look up Alpha-Gal allergy. It is a biological weapon program, supposedly coming from the lone star tick which encompasses the habitat of basically the Southern United States (although nobody has proof that it is tick-borne), that causes severe meat allergies. It is becoming far more common and only prevents a person from consuming red meat. If they do, they can get anaphylaxis.
You won't eat ze beef and you WILL be happy.
