Antiterrorism = food supply decentralization

From the Washington Post via Daily Kos:

The analysis by Wein and graduate student Yifan Liu considered what might happen if terrorists poured into a milk tanker truck a couple of gallons of concentrated sludge containing as much as 10 grams of botulinum toxin, a potent bacterial nerve poison now popular in low doses as a wrinkle eraser.
Because milk from many sources is combined in huge tanks holding hundreds of thousands of gallons, the toxin would get widely distributed in low, but potentially lethal, concentrations and within days be consumed by about 568,000 people, the report concludes.

The article was focusing on the conflict between scientific freedom and national security, but the larger and continually marginalized issue is at the heart of the report itself: a centralized food production and distribution system is infinitely more vulnerable to sabotage/terrorism than a diffused network of local and regional food systems.
