A popular children's thermometer has been recalled after the manufacturer received reports of injuries such as skin burns.
Hauppauge, NY-based BearCare initiated a voluntary recall of its rechargeable Walnut Wearable Smart Thermometer. The wearable device is intended for continuous chest temperature monitoring of children up to age 6. The device has a silicone exterior designed to resemble a cartoon penguin. The thermometer was sold and distributed from December 2022 to April 2023 through Amazon, Walmart (online), and www.walnutcares.com.

If users of the thermometer observe any substance leaking from the device's exterior, any corrosion near the smart sensor on the back of the device, diminished battery life, or connectivity issues with the Walnut app, these are indicators of a failing device, BearCare said. In addition, a sensation of warming or heat at or near the site or redness and irritation on the skin are also signs of that the device is failing.
Consumers should immediately stop using the Walnut Thermometer, and caution should be taken if there is evidence of moisture or leakage because this may pose a risk of chemical burns to children as well as caretakers handling the product, the company said. BearCare also urged consumers who have used the device on a neonate or infant to check other areas of the baby's body, including the mouth and eyes, because it is possible for corrosive fluids to be transferred and cause chemical burns or toxicity if swallowed. The company said parents or caretakers should seek medical care if they or their child were exposed to moisture coming from the device or if they experience any symptoms related to this device failure.
BearCare said it initiated the voluntarily recall of the Walnut Thermometer after receiving consumer complaints of minor to severe skin burns and skin irritation in children that used the product. The company said it is "thoroughly evaluating" these complaints.
