A self-described "natural" baby product company is recalling 10,500 of its stainless steel bottles and cups for toddlers that pose a risk of lead poisoning, the U.S. Consumer Product Safety Commission announced Wednesday.Three of Green Sprouts' products are subject to the recall: its 6 ounce stainless steel sippy cup, its 8 ounce stainless steel straw bottle, which have the tracking numbers 29218V06985 or 35719V06985, and its 6 ounce stainless steel sip and straw cup, which has the tracking number 33020V06985, according to the recall notice.The tracking numbers are printed on the bottom of the bottles, which were sold in aqua, pink, green and navy colors, according to the notice.Green Sprouts said that the portion of the product containing the lead had not been tested “because it is inaccessible under normal use.”“Had we known that a component containing lead in these products could become accessible, we wouldn’t have put them on the market," the company said.On its website, Green Sprouts founder and president Becky Cannon wrote the company has "holistic foundations" and is inspired by "the traditional Japanese approach to health and well-being.""
