A woman who doesn't want her breast milk to go to waste has taken out a newspaper ad in hopes of selling it.

Martha Heller, 22, took out an ad in The Gazette newspaper offering 100 ounces of her breast milk for $200 or the best offer.

Heller said her freezer is overflowing with breast milk she has pumped since August. Her 4-month-old daughter won't drink from a bottle and the supply is piling up.

Heller now donates to the University of Iowa's Mother's Milk Bank, but the 100 ounces of milk she wants to sell were pumped before she went through the screening process for the bank and cannot be donated.

Linda Klein, a lactation consultant at Mercy Medical Center in Cedar Rapids, said breast milk can generally be stored in a freezer for up to six months.

Heller said she researched laws regarding the sale of breast milk and couldn't find any in Iowa.

Don McCormick, a spokesman for the Iowa Department of Public Health, said he was not aware of any laws in Iowa restricting the sale of breast milk, but that state health officials advised against it.

Heller said she hasn't received any legitimate calls about her ad.

"There was one prank caller," she said.
