Lead found in Michelle Obama's White House vegetable garden

(U.K. Guardian) - It was meant to be a show case for healthy living, with the first lady, Michelle Obama, personally putting hand to pitch fork in a crowd of school children to dig up the first White House vegetable garden in more than 50 years.

Instead, an embarrassed White House admitted today that the plot - whose lettuce, herbs and other produce have been consumed by the first family, visiting dignitaries, local school children and a women's homeless shelter - had tested positive for elevated levels of lead.
