@Lasse - you are right for this part. EPA wants products labeled correctly and instructions to handle, use and dispose of safely. I don't think that the EPA gets into efficacy, but most products like this have indigents that already have tests run - Busan 77 already had all of these in this case. There is a pig/sheep livestock drug Levamisole in Flatworm Exit that is regularly used in aquariums to kill flatworms - I wonder if the EPA would approve this... the EU doesn't have a problem with it even though it is not labeled as a pig dewormer.
The fraud is a separate issue, which I understand is not fully settled yet.
