On Wednesday, the White House released a new video of the Kitchen Garden getting prepared for winter, with the addition of hoop houses. The video got a lot of attention on the internet and in media. Shortly after, the old myths of dangerous lead levels in the Kitchen Garden started to circulate again.
So to reiterate what has been previously posted here numerous times:
There is no dangerous lead level in the White House Kitchen Garden. There never was, to begin with. And no toxic sewage sludge was ever applied to the Kitchen Garden, either.
The most recent soil tests of the Kitchen Garden were done in August, and found a lead count of 14 Parts Per Million, down from 93 PPM in March, the number released by the National Park Service when ground was originally broken for the garden. Produce from food gardens are considered safe for human consumption when garden lead levels are between 300 and 400 parts per million. A post about the lead levels in the Kitchen Garden, which includes interviews with three of the top soils scientists in the US, is here. A full statement from the White House about their most recent lead tests is here.
