The United States Food and Drug Administration has said it is reviewing a new ceramic heat emitting device, saying it could pose a risk to people who eat meat, fish, poultry and seafood.
The FDA said the device, which is about the size of a shoebox, would emit heat that could cause burns and irritation if used improperly.
The agency is also assessing the safety of ceramic magnets that were used in a ceramic knife in a New Jersey case.
It is unclear if ceramic magnets were used to make the knife, but it is not clear if the magnets were actually heated, the FDA said in a statement.
The agency said in its statement that it was aware of the New Jersey incident and that the agency would consider a review of the ceramic magnets if the FDA determines they pose a health risk to consumers.
The agency also said it was “reviewing the safety” of other ceramic knives.
Ceramic heat-emitting devices have been used to treat injuries related to heat, but the FDA has been cautious about using them to treat cancer and other conditions.
The devices emit heat, causing burning and irritation.
According to the FDA, the device could be dangerous if it were used improperly, or if it was used in combination with another device that is not intended for use with other medical products.
Earlier this year, the agency announced it would review whether to approve a new chemical-manufacturing process for the ceramic knives, which it said could be safer for consumers.
In an interview on Wednesday, FDA Commissioner Scott Gottlieb said the agency was “not looking to ban the use of these devices, we’re looking to find out what we need to do to prevent the use” of ceramic knives in medical settings.
