26 problems carry keeping food safe

Food-safety problems sit between the farm and the eater: hermetic grain storage that virtually eliminates post-harvest losses in trials yet reaches fewer than 12 percent of the farmers who need it, Brazil losing 35 percent of its fruit and vegetables before they even reach the first collection point, and a proven aflatoxin biocontrol going unused while contamination keeps causing liver cancer. Detection, storage, and adoption fail more often than the underlying science.
