of course the irony is that it doesn't even matter. We already know China (1) tried to cover it up, screwing the rest of the world, and (2) has poor wet market sanitation practices that seem designed to cultivate these kinds of diseases. Those issues are already bad enough.
Honest question: Is that a fair/accurate generalization to make? If Hell's kitchen episodes and accounts from food industry workers are any indication, sanitation practices in food handling establishments elsewhere are not necessarily always stellar either. And surely China has some equivalent of WholeFoods?
One ought to be careful not to attribute a characteristic differently depending on whether they belong to the class of people in question[0]. If it turns out that reality is that some chinese establishments have poor sanitation practices just like some US establishments do, and it just so happens that they got unlucky (perhaps partially due to not-so-directly-related aspects like zoning law differences or propensity for higher bat populations due to local fauna/flora ecosystems), the us-vs-them blaming game doesn't necessarily have as strong legs to stand on.
The issue with wet markets isn't the sanitary practices of their workers so much as the fact that meat and other food is handled in very close proximity to live animals being slaughtered, and this combined with a large volume of foot traffic. Granted, I haven't seen all episodes of Kitchen Nightmares, but I've never seen slaughter of any kind taking place at a restaurant in that show, let alone at a restaurant that is visited by tens of thousands of people each day.
