NEW YORK (AP) — Walmart is recalling about 850,000 stainless steel water bottles because the lid can “forcefully eject” and unexpectedly strike consumers — resulting in permanent vision loss for two people to date.

The lids on the 64-ounce stainless steel bottles can eject and strike consumers, two of whom reported permanent vision loss as a result, safety regulators said.

Walmart is recalling its Ozark Trail 64 oz Stainless Steel Insulated Water Bottles because the lid can forcefully eject when someone tries to open the bottles after food or carbonated or perishable beverages, such as juice or milk, have been stored in it for a period of time.
