Modeling an Attack on the Food Supply
Botulinum toxin is the most deadly toxic substance known, with only a millionth of a gram needed to kill an adult human. The calculations were done using mathematical models of the distribution of the milk supply.
The good news from the study is that security, testing and early warning systems could be implemented that would raise the price of milk by only 1 cent per gallon. The National Academy of Sciences has suggested that the study be used as an example of further research into homeland security measures.
