Recalled baby products linked to more than 100 baby deaths are still available for purchase on Facebook Marketplace, four congressmembers say in a letter sent Friday to its parent company, Meta.

Despite multiple requests by federal regulators to take the items down, Facebook Marketplace still has the items for sale on its platform, the lawmakers recently wrote in a letter to Meta, which operates Facebook, Instagram, WhatsApp and other services.

In the letter, sent Friday to Meta CEO Mark Zuckerberg, the lawmakers singled out the Fisher Price Rock ‘n Play, an inclined infant sleeper associated with approximately 100 infant deaths and recalled in 2019, and the Boppy Newborn Lounger, a prominent infant newborn lounger associated with infant deaths and recalled in 2021.

The loungers were sold for between $30 and $44 from 2004 to September 2021 at various retailers, including Target, Pottery Barn, Walmart and Amazon.

The Consumer Product Safety Commission (CPSC) has formally requested — about 1,000 times a month — that the platform take these products down, but they are still available on the platform, the letter said.

It is unlawful to offer for sale a CPSC-recalled product on an online marketplace or to sell or donate a recalled product in any other manner, the CPSC says on its website.

A series of newborn loungers from The Boppy Company were recalled in September 2021 after eight deaths were linked to the product. Soon after the recall, two more infants died while sleeping on the pillows, the Consumer Product Safety Commission said in a news release in June.

The most recent letter, signed by Reps. Cathy McMorris Rodgers, (R-Wash.), House Energy and Commerce Committee Chairman Frank Pallone Jr., (D-N.J.); Gus Bilirakis, (R-Fla.); and Jan Schakowsky, (D-Ill.), questions whether any proactive measures were taken by Meta to prevent these types of postings in the future.

“Meta’s failure to prevent recalled products from being posted for sale on its platform has resulted in your users and their children being placed at risk of purchasing and using a product that CPSC has found to pose a serious risk of injury and potential death,” the lawmakers wrote, asking the company to respond by Aug. 31.

In June, the CPSC’s commissioners sent a letter to Zuckerberg calling on him to do more to prevent the sale of the recalled products. But new postings continue, according the lawmakers.

In the lawmakers’ letter, the members of Congress asked for more information about Meta’s product safety policies, how it monitors recalls and questions and how many full- and part-time staff members are on its consumer product safety team.
