Are Stainless Steel Water Bottles Safe?

The lead questions about steel bottles come from how some insulated ones are sealed. In February 2023 Consumer Reports said the Bindle sip and stash bottle had been voluntarily recalled after CR tested a sealing dot in its bottom storage compartment and measured over 1,000 times the amount of lead allowed in many consumer products. Health Canada’s recall notice said the dot could pose a lead exposure risk if unpackaged food was placed in that dry storage compartment.

Stanley said in a statement quoted by Nebraska Medicine that it uses an industry-standard pellet to seal the vacuum insulation at the base of its products, that the sealing material includes some lead, and that once sealed the area is covered with a durable stainless steel layer. Nebraska Medicine reported that YETI uses a similar vacuum sealing bead containing some lead and says it is completely encapsulated and inaccessible, and that Hydro Flask and Owala have stated they do not use lead during the sealing process.

As for the steel, Health Canada says stainless steel is commonly composed of iron, chromium and nickel, and that the chromium helps form a very thin, protective surface layer that gives it corrosion resistance. Its cookware guidance advises people who are allergic to nickel not to use cookware containing nickel.
