this topic came up at one of the beekeeper meetings a little while ago.
i think there was some valid concerns voiced.
the big one is the potential for someone to turn up, swab test, and declare all supers need to be burnt. this is without any other finding or other cause to be there. if there is a history of afb problems, going through hives first then following up on the supers is i think fair enough. but just to turn up without cause, is a little heavy handed and a waste of resources. why test someone who doesn't have a problem. while i doubt that would happen in practice, its a possibility.
this also leads into the potential for misuse (ie due to personal conflicts). while that risk has always been there, its never been able to have a big effect. at worse you might burn a few hives that don't have afb, now they can burn all your supers.
i think there is a good argument to make sure there is good procedures in place and a chain of evidence before that happens.
however what was pretty obvious was the sheer lack of understanding of afb and poor mentality around it.
for eg
all hives/supers have afb spores in them.
pcr testing will always show the few spores thats always in the gear therefore its just dumb luck if they don't find it.
afb is a light switch, you either have it or you don't.
doing the bare minimum afb control means your a good beekeeper.
hives will clean up afb on there own (therefore you can clean it out fairly easily).
people with high rates of infection should be given a chance to clean it up (even tho the don't have the skills/ability to do so).
beeks should be compensated for their loss by the public even tho most of that will be beeks scamming the public.
clearly a few of these things appose each other which really shows how stupid it is.
not all hives have afb spores in them, most do not.
there is levels of infection. as spore count goes up so does the risk of the hive getting clinical infection. its not a light switch. this is in the yellow afb book. this is the opposite of the claim that all hives have afb spores. if its a light switch then every hive would have clinical afb, which of course is not true.
some hives do clean up afb, tho its not many. many will still exist with subclinical levels and they can go clinical levels some years down the track (something i have found first hand).
of course doing only what is legally required does not make you a good beekeeper, in fact i would call that bad beekeeping. the amount of work, effort and cost that goes into good afb control practices is a lot. we can see the results of that, when the money goes so does the afb control. i know several long term beeks who have afb problems, all because they short cut afb procedures to save a few cents. now its costing them big dollars.
someone used the example of a beeks with a 50% infection rate and that they should be given a chance. the amount of years it takes to get things that bad, there is almost no hope of that person ever getting on top of it. most of the supers will be infected and i highly doubt they are going to buy in large amounts of hives only to burn them. most likely is that, at best, they will end up burning all their hives. but as they have more supers than hives to put them on they will have a stockpile in the shed which will be sold off years later to unsuspecting buyers. the exact situation we want to avoid.
compensation for beeks will mean there is no downside to having infected hives, so there is no reason for afb control. in fact around the world beeks breed infected hives so they can claim the compensation. if thats 100% beek funded, expect your afb levy to have a few zeros added to it. if its public funded, imagen the fallout when public realize they are being scammed. double so while there is the idea of making big money off manuka and the greedy sods are scamming the public. beekeeping is a small industry that can not afford to be offside with the public. the politics alone will demand that beekeeping become more regulated and controlled by politicians.
imho the testing on supers helps close the afb loophole which allowed people to infect other peoples hives via the supers.
on another note, there is talk of a possible big increase in hives required for pollination. of course pollination is a great time for diseases to be spread amongst bee hives, which will make things so much worse. all of us beeks need to lift our game to stop the spread of pests and diseases.
