Dairy-consuming Washingtonians could find themselves with extra petty cash on hand. Thanks to a class action settlement, anyone in the District who bought milk or milk products (e.g., cheese, yogurt, cream, etc.) since 2003 may be entitled to a payment of up to $20. Residents of 15 other states are also eligible for the payout.

Sounds good, right, but perhaps a bit odd? The background of this story isn’t so nice.

Major US dairy producers agreed to a $52 million settlement after they were accused of slaughtering more than 500,000 cows to reduce milk supply and inflate prices. The suit states that a National Milk Producers Federation trade group oversaw a “herd retirement program” between 2003 and 2010. In this program, dairy cooperatives bought out herds of cattle and sent them for early slaughter.

This action reduced the supply of raw milk, driving up dairy prices.

You can submit a claim on Boughtmilk.com to receive the payout. But hurry, the deadline for submissions is January 31, 2017. To be eligible, you must have bought milk or milk products from a DC grocery store for personal use and not for resale.

For those of you who don’t save decade-old supermarket receipts, fear not, no proof of purchase is required. Just name and email address. And yeah, seems sketchy, but we verified this story on Snopes and other news sites.
