Makes very interesting reading and explains why SBI wanted my permission to take bee samples when on health inspection this year, but its not without a slight misinterpretation as I have bees on one site that is shared and there was one colony with EFB last year, the colony was burned and all is clear this year but as our SBI said our apiiaries are red flagged this year because of last but now has been given a second all clear. This means that samples last year may well have been examined with a different list of things to look for.
