FDA (IMO) are the 3 most dangerous letters ever bestowed upon USA.
Underwriters laboratory listing only means a product meets their specifications. Doesn't make a product safe or not safe. When I was a child, UL listing only meant there was the (only at the time) UL knot in the cord. This knot was supposed to prevent tugging on the connection point.
The first time I was electrocuted was from a UL listed lamp.
It had the knot... but the hole the cord fed through was too large to allow the knot to be useful. Lamp fell off the table. 6 yr old me decided to plug it back in before I got in trouble. 110Vac blackened 3 fingers temporarily.
Some of my best electronics aren't UL listed. Including a high powered lamp I trust and kept over my fish tanks for several years.

Meeting their specifications means that it is not likely to catch fire can handle drops temperature has overcurrent protection, etc. I have been involved with a UL lab certifying and electronic product.
