people are now passing it back to pigs

The thing is, pandemic just means worldwide, it doesn't mean deadly. It certainly is worldwide - New Zealand, which is far from Mexico, had a number of cases. That's what modern air travel does.
As it turned out, it's not very lethal, and doesn't pass easily from one human to another. But the next pandemic might. So authorities do need to have rapid response plans ready, and also be prepared for the fact that they may not be needed after all, however much they cost.
It all depends how much money you want to spend on countering risk. London Transport doesn't invest in snow-clearing equipment because it thinks London doesn't get enough snow to make it worthwhile. I think that's right, but people get upset because the one snowfall a year can stop the tube running. But would they want ticket prices to go up to defray the cost of anti-snow gear?
