BRUCELLOSIS...
Judgement: Cattle and horse carcasses affected with brucellosis are approved (after removal of affected parts), as Brucella bacteria remain viable for only a short period in the muscles after slaughter. In acute abortive form (after the miscarriage), cattle carcasses are condemned. Pig, sheep, goat and buffalo carcasses require total condemnation. Heat treatment may be recommended in some areas for these species due to economic reasons. Affected part of the carcass, udder, genital organs and corresponding lymph nodes must be condemned.
In other words, Brucellosis infected meat is ok to eat, unless it is in the abortive phase. Then the meat can still be eaten if it is completely cooked.
Is the United States a developing country?
