Ion batteries, if ingested, can cause internal bleeding.
Small parts of other toys can pop up easily, meaning they can pose a risk of choking on young children, while the blade edges of some toys are sharp.
There is no contact information from the manufacturer or importer on the toy, which means they cannot be promptly recalled if necessary, officials said.
Martin Veale, member of the B & NES community service cabinet, said: "The fidgety spinner is new and is currently very popular among young people.
We want to make sure that young people are safe when using these devices.
"Our trade standards officers have been working on some spinning machines that are being sold and have found that they have very small dangerous parts, so it is correct for them to withdraw from the sale for public safety.
Anyone who buys a fidgety spinner should buy it from a reputable trader and make sure that a safety warning is clearly visible on the package.
