Spotted in This is Brighton Magazine:

“REAL BABY FOOD
A pregnant woman put an ad in the window of Infinity Foods (Brighton) to sell her placenta. The 21-year-old, who intended to donate the body part for friends to eat if no offer was received. said: ‘I was going to throw it away but thought someone might be able to use it.’“

And we are pretty sure we know who she is… will let you know.
