How to prevent Q fever in goats?
Q Fever can be prevented by avoiding high densities of animals during kidding, lambing, and calving seasons. Carcasses, aborted fetuses, and placentas should be promptly removed to minimize spread from potentially infected materials. Pregnant, infected females should be isolated from the herd. Workers should wear personal protective equipment (PPE), including gloves and masks, when handling potentially infectious animals or infected tissues. Pregnant women should avoid handling aborted materials from small ruminants or assisting with deliveries of premature or aborted lambs or goat kids due the risks to their own pregnancy associated with exposure to Coxiella and other zoonotic pathogens. Barns, especially birthing pens, should be thoroughly cleaned and disinfected with “a 10% solution of bleach, a 5% solution of hydrogen peroxide, or a 1% solution of Lysol®” (The Center for Food Security & Public Health - Q Fever Factsheet). Exposure to dust should be minimized, and spreading of manure avoided under windy conditions. Proper composting of manure will greatly reduce the load in manure. Milk should not be consumed raw; pasteurization will eliminate C. burnetii from milk.

However, it is important to note that this test does not determine if animals are actively shedding the bacteria, just that they have developed antibodies to C. burnetti. At the farm level, PCR testing of bulk tank milk can detect bacterial shedding.
