Disease burden of urban livestock

This is an interesting article suggesting that, despite what one might assume, keeping of urban livestock does not have a clear relationship to disease exposure.  It's important for research like this to occur in order to paint a clear picture of what the real risks are or are not of practices common in the developing world and among the poor, like smallscale livestock rearing in urban areas.  If something is genuinely dangerous, policies can be made to diminish or mitigate that risk.  And if something is shown not to be a risk, this can bolster the arguments of the poor, who are often broadsided by heavyhanded laws and regulations that can be more informed by prejudice than by scientific fact.
