Last week, Mayborn USA — the makers of Tommee Tippee Sippee cups — issued a voluntary recall of 3.1 million spill-proof cups. According to Tommee Tippee, mold can grow on the removable valve inside the cup if it remains wet or moist. But in which states were the Tommee Tippee Sippie cups recalled, and perhaps ever more important, which models were affected?

The bad news is that the sippy cup recall applies to all states and to Canada, according to Tommee Tippee:

Tommee Tippee Sippy Cups with a removable, one-piece white valve...[and] sold between December 2014 and March 2016 in the USA and Canada [have been affected].

However, the good news is that, of the company’s numerous cup designs, only six models have been recalled: the First Sips Transition cup, the Trainer Sippee cup, the Sippee cups, the Sportee bottle, the Insulated Sippee tumbler, and the Cute Quips Sippee cup.

According to Tommee Tippee, the problem with these cups lies in a small, white valve:

Mold can develop on the removable, one-piece, white valve inside the cup when it remains wet/moist and is infrequently cleaned.

And this mold can lead to gastrointestinal problems:

Although the resulting risk of gastrointestinal symptoms and infections in consumers with compromised immune systems is low, the product is being voluntarily recalled in the US and Canada.

The Sippee cups in question were designed to be used by children aged 4 to 12 months old, and the company issued the recall after more than 3,000 consumers reported seeing mold in Tommee Tippee cup valves. According to CNN, there were also 68 reported case of illnesses that that were “consistent with drinking from a cup with mold.”

Tommee Tippee and Mayborn USA are urging customers with recalled Sippee cups to stop using them immediately and to “contact Mayborn to receive a free replacement cup” — even if the valve appears clean and the cup appears OK.

Consumers can request a replacement by calling Mayborn USA Inc. toll free at 1-877-248-6922 anytime between 8 a.m. on Monday, May 30 through 3 p.m. on Saturday, June 4, or by visiting the company’s website. However, it is important to note that, in order to receive your new cup and valve (pictured above), the cup lid and white valve needs to be returned Tommee Tippee.

If you no longer have your cup but still want to participate, you can get a replacement cup, lid, and valve if you have the receipt for your cup(s).
