When Michelle Obama created an organic vegetable garden on the White House lawn earlier this year, the move was greeted with positive headlines and excitement among the food advocacy community. Here, we thought, was a First Lady who understood the importance of locally grown, whole and organic foods in her family's diet.
Unfortunately, something happened on the way to the realization of the First Lady's good intentions. Recently the National Park Service discovered that the White House lawn, where the garden was planted, contains highly elevated levels of lead -- 93 parts per million. It's enough lead for anyone planning to have children pick vegetables in that garden or eat produce from it to reconsider their plans: lead is highly toxic to children's developing organs and brain functions -- however, it's below the 400 ppm the EPA suggests is a threat to human health.
