Claim: Stanley cups contain lead

Question

Users on TikTok have been using at-home test kits to check if their cups contain lead. Stanley's FAQ states: "Our products are FDA tested and approved, and all contact surfaces are guaranteed to be safe and BPS/BPA-free." However, it does not mention the inclusion of lead. A TikTok user tested the bottom of the cup, which contained lead. The only part of the cup that contains lead is the bottom, which is normally covered. Whenever the paint comes off, it is advised to toss the cup.

I believe this statement is true because a lot of insulated cups do contain lead but i also believe that Stanley would not produce a cup with just lead and majority of the cup is stainless steel and is extremely unlikely that you will consume or come in contact with lead. A lot of people believe what they see immediately so just like the Stanley became such a sudden trend people can also believe immediately that they are consuming lead just because of one person testing the base of the cup and making an assumption

I see this statement truthful. According to the WCNC,"Stanley tumblers are sealed with a small trace of lead in their insulated cups, but the lead is completely enclosed by stainless steel and does not come into contact with your drink." That this the hard written facts Stanley Manufacture has said.

I believe this statement since there are plenty of water bottles and insulated cups that contain lead. From the website named"Lead Safe Mama's," the writer confirms that the Stanley Cups do in fact contain some materials of lead.  Tamara Rubin, the writer and owner of Lead Safe Mama, shows a statement made by the Stanley brand that there is a "very high level of outdated/unsafe lead. The pellet is completely enclosed by a stainless-steel cover making it inaccessible to consumers.

I agree with your statement. After researching this topic I found multiple sources that were looking into Stanley cups containing lead. Most of them claimed that the Stanley manufactures had sent out emails claiming that all of their products were up to industry standard. WNCN states that, Stanley did say it seals its insulated products with an industry-standard pellet that includes some lead. Stanley said the pellet is completely covered and enclosed by a stainless-steel cover, making it inaccessible to consumers."  Adding some textual support to your statement can help back up your claim. Finding the original statement or video of the person claiming that they tested for lead could support your claim.

This statement is misleading. Stanley cups do contain led, however it is covered up and inside the bottle. Therefore, the lead within is safe and unable to contaminate your drink. According to Kate Underwood on Green Matters, the Stanley cups are made with a lead solder, similar to many other reusable insulated bottles.

I agree with this fact-check, I think TikTok is not a reliable source and we should not believe what ONE person is saying. TIME magazine also posted an article with Stanley's reaction to this comment and the company said that the cups do contain lead but they are then coated with stainless steel making them non-harmful.

I agree with this statement considering it comes form the company itself and, in general, a lot of products contain lead, but it is not considered a health risk because it does not contaminate the consumer or their contents they have in their cup.

Answer 1

Yes, Stanley cups do contain lead, but not to a point where the consumer would come in contact with the lead. After claims started spreading throughout social media Stanley issued a statement stating that "Once sealed, this area is covered with a durable stainless steel layer, making it inaccessible to consumers. Rest assured that no lead is present on the surface of any Stanley product that comes into contact with the consumer nor the contents of the product." Considering this is coming from the company itself it should be held as highly reliable. Stanleys meet all US regulatory requirements and the at home tests people are using were not reliable compared to EPA-certified ones.

The source used was BBC and was very reliable because it reached out to the water bottle brand itself and got commentary on the issue. It provided facts and data from the source. 

Overall, we can conclude Stanleys have lead in the water bottle, but none of it would reach the consumer or be at any sort of health risk because it is sealed.
