You were right, offal has to be cooked:

'The slaughtering of cows, sheep, deer, goats and pigs must be carried out in an

approved killing facility within a dog-proof enclosure to prevent dogs from having

access to uncooked viscera. The offal from these animals must not be fed to dogs unless

it is first cooked by boiling for a minimum of 30 minutes.'

freezing was to prevent sheep measles, and that was the meat not the offal.

I thought it was cooking to a certain temp for a certain length of time? Or just having offal holes that everything got dumped into...

Freezing offal was the requirement under the hydatid elimination scheme in NZ (I forget to what temperature and for how long) - I think it is still in place to minimise sheep measles

While granulosus is a less lethal problem than alveolar hydatid disease, it is still pretty horrible, and i was not implying it was trivial at all. But alveolar is truly awful, the stuff of nightmares and dodgy medical shockumentaries

During the 1980s there was a hydatid scheme in mid Wales which allowed free wroming of farm dogs every 3 months This considerably reduced the incidence of hydatid cysts

Minimise or eliminate? Cooking to a certain temperature for a certain length of time works (can't remember far enough back for the important details there!), but surely this is one disease where the risk outweighs any need to just use caution to try and avoid human infection?

Not trying to support RMB in any way but my understanding is that freezing the meat should minimise the risk from hydatid disease.

I have a client who has also had multiple surgery after Hydatid disease, not to be risked in my opinion.

I meant granulosus

Echinococcus isn't that nice I know a farmer's wife who lost her spleen because of it

There are 2 forms of hydatid disease, of which only one, the milder form, caused by Echinococcus granulosus, is present in parts of Wales. the more severe form is alveolar hydatid disease caused by Echinococcus multilocularis and this is one zoonisis you do not want to get. It is however pretty rare. It is the existence of this parasite on mainland Europe that has allowed the UK to keep the derogation for tapeworm treatment in the PETS regulations

If people ask I strongly advise them against raw diets, if they insist then I suggest 6 weekly worming.

There has to be an increased risk, but I believe in this country it is very localised to parts of Wales.

Obviously we ought to be careful or our kickbacks from the pet food manufacturers may be in danger.......
