It is approved by the CDC for its safety and effectiveness. Growers are also researching alternative processes that could achieve even better purification. Its discovery attracted attention. The USDA and CDC took a greater interest in sprouts, because the growing conditions for seeds are also favorable growing conditions for bacteria and because as a raw food, sprouts do not benefit from sterilization by cooking. Common garden vegetable seeds are also subject to these same risks.

Only 700 people reported salmonellosis in the two 1995 sprout incidents described in the JAMA article.
