Just so I understand correctly.
You are saying that people who eat pig that is infected with tuberculosis cannot catch the bacteria and then come down with the generalized infection?
Does that include the three main species?
Literature in veterinary studies indicates that pigs can and do come down with all three M tuberculosis as well as M bovis, besides the usual chicken carried M avium?
The chicken form does not transmit directly as an aerosol, nor by eating pig, but the pig infected with M tuberculosis, actually harboring the bacteeria in it's tissues, when these tissues are consumed by a person, thus ingesting the bacteria, thus exposed, the bacteria does not multiply in the person's nodes and cause disease?
Does your general statement also apply to perhaps contaminating a wound on the person via touching an exposed leaking tubercle and thus transferring a few hundred thousand bacteria directly?
I really would like to see those studies.
The human method of trsnsmission is through breathing infected droplets exhaled by an infected person. Humans have also been infected from cattle via unpasteurized dairy products. Chickens are not pigs, and regardless are not forbidden under the food laws.
To recap, TB was not and never was a factor in the formulation of the food laws regarding never eating pigs. The stricture is, the animal must go on a cloven hoof and chew its cud.
Four critters known to OT Hebrews are specifically excluded for lacking one or the other characteristic (pig, camel, hare, and hyrax; frankly I'd never heard of a hyrax before this *).
