Leaked Memo Reveals Concerning New Brain Disease In Canada (theguardian.com) 102

hackingbear shares a report from The Guardian: Residents [in the Canadian province of New Brunswick] first learned of the investigation last week after a leaked memo from the province's public health agency asked physicians to be on the lookout for (neurological) symptoms similar to Creutzfeldt-Jakob disease (CJD). For more than a year public health officials have been tracking a "cluster" of 43 cases of suspected neurological disease in the province with no known cause. Despite the initial similarities, screening produced no confirmed cases of CJD, a rare, fatal brain disease caused by misformed proteins known as prions. Only a single suspected case was recorded in 2015, but in 2019 there were 11 cases and 24 in 2020. Researchers believe five people have died from the illness. Health officials have refused to disclose the precise locations of the cases. "The majority of cases are linked to the Acadian peninsula, a sparsely populated region in the north-eastern part of the province," the report says. Some of the symptoms include memory loss, vision problems, abnormal jerking movements, unexplained pains, spasms and behavioral changes.

              That's because of the limited licenses and government restrictions. The problem is deer reproduce like rabbits if there is no natural predators. Unless they start introducing and have thriving, large packs of wolves and other top predators, you'll have a deer problem.

            How is that compatible with prions being extremely difficult to sterilize from instruments? Whatever is eatable by bacteria should be easy to destroy considering that bacteria can't involve extreme processes to break stuff down. But we know prions to be very stable.

              OK, that would be a way of persisting, though not in the soil. They could use the proteins made by the plant to fold into their favorite shape. Or you could sterilze the soil, and then prions could presist, as most of them are relatively stable as long as nothing eats them.

              P.S.: Just so you understand:
              Prions are essential to life. What prions are is a self-catalytic protein shape. We depend on prions to shape the proteins that we use into the shapes we need them to have. But just occasionally one form

            Sorry, but nope. It's the opposite.

            The linked article states that prions are persistent, NOT eaten by bacteria or broken down in the soil, even for years. Actually, that and disease transmission are the points of the article – animal-to-soil-to-plant-to-animal disease transmission is a real thing. The last sentence of the abstract says it.

            It's scary. Mammal-to-plant-to-mammal transmission of disease particles that do not break down in the soil.

        my father died from CJD back in the early 2010s he was one of apx 30 canadians who die from CJD every year. It's a fucking horrid thing to witness. CJD is the human version of Mad Cow Disease not the other way around. After he died it was mandatory that he be cremated at a much higher temperature than a normal cremation temp in order to make sure every possible contaminant was killed. The crazy thing was that he was in Britain in the 1980s during the MadCow outbreak, no specialists have been able to connect the two because of all the years that had passed (30?). but, possibly like lung cancer and other diseases in the elderly things lay dormant until late in life when the immune system isn't as healthy. Possibly he did ingest something years ago that lay dormant until old age? What is clear is that there is no cure and it's nasty and kills within months of diagnosis, there is NO survival.

        • If this can be passed to plants then back to animals, and lingers in the enviornment, then every farm where a case is found needs to be treated as a bio-weapon spill.
          • Pretty much. The question needs to be asked can mad cow prions be detected in the soil?? I they persist then they would still be there. But it could be proactive to test soils randomly. If not to understand the origination of prions.

        That's a rather twisted flavor of corruption that takes a health and safety policy from burn-the-farm-at-the-stake to nothing-to-see-or-test-here, in a matter of a few years.

        The "mysterious" one, should be brought to trial. And it shouldn't be that damn hard to figure out whodunnit. Government is still damn good at killing trees in the name of paperwork jobs in triplicate. A policy change like that, should have a paper trail...

          2014 would have been during the Harper years. His Conservative government was furiously getting rid of regulations. At one point they deregulated the meat plants so they self inspected, resulting in deaths and our trading partners no longer accepting our meat. Sometimes regulation is needed as businesses self policing just doesn't seem to work.

      • Easy fix: Have mandatory 100% testing for mad cow disease, instead of random sampling. And test all animals not just cows.
        • Even that's not really fixing anything. Those animals that are sick have been crapping everywhere in the environment leaving prions behind for another animal to find years later including humans.

    In the late 1980s - 1986, 1987 or so - the UK experienced a devastating outbreak of what became known as "Mad Cow Disease". This is relevant to the above OP and linked article because, essentially, CJD is the human form of BSE (and vice versa).

    There is some interesting background on BSE to be found here [wikipedia.org].

    The linked Wikipedia article includes the following:-

    "Alan Colchester, a professor of neurology at the University of Kent, and Nancy Colchester, writing in the 3 September 2005 issue of the medical journal The Lancet, proposed a theory that the most likely initial origin of BSE in the United Kingdom was the importation from the Indian Subcontinent of bone meal which contained CJD-infected human remains."

    I came across a slightly different theory, which is as follows:-

    In order to accelerate the growth of cattle - primarily beef cattle raised for human consumption, but also for dairy herds - farmers include "cattle cakes" in the diet of their herds, like this [blogspot.com]. These cattle cakes are, in fact, the leftover remains of slaughtered beef cattle, ground up in to bonemeal. The ingredients are not selectively filtered, so they include not just skeletal bones, but all parts of the slaughtered animal, including the brains and spinal column. This is undisputed and a practice that has been going on for decades.

    In the UK, the epicenter of the outbreak in the late 1980s, the government department responsible for regulation of farming (I think it might have been known as the "Ministry of Agriculture, Fisheries and Food", or MAFF, at the time), changed a rule concerning the creation of "cattle cake". The changed reduced the amount of time that the bonemeal cakes had to be "cooked", reducing the energy cost of producing the foodstuff and thereby reducing the production costs for the manufacturers.

    As a result, if a pathogen existed in the brain or spinal column of a steer that was slaughtered for beef, then when that animal's remains were recycled as "cattle cakes", the pathogen may survive the cooking process and re-enter the food chain when the cake was fed to the next generation of cattle. The UK looked at a number of other contributing factors, for example such as the possibility that infected brain or spinal column material could be spread as a fine mist in an abattoir given that typically a bovine carcass is cut up using a purpose-build band-saw.

    Unfortunately, it could take several iterative generations of feeding animals on tainted cattle cakes before any pathogen reached sufficient concentrations in the host animal for them to develop symptoms (which in cows included passing out, an inability to stand or to appear "drunk" when walking, followed, ultimately, by collapse and death).

    As I understand it, the British government quietly reverse the rules on "cooking" cattle cakes and over a period of time the disease was wiped out. There was never any form of public admission as to the cause; rather there was enough speculation and alternative theories to allow the story to be left as "cause not conclusively determined".

    Obviously I need to emphasize that there's nothing in the linked Guardian article to suggest that this has anything to do with BSE or the diets of the individuals concerned. Although the UK's experience is now some 30-35 years ago, there's a pretty good chance that Canadian authorities will include at least one medical professional who lived through those times and will recall the same background I set out here. That, in turn, could prompt them to chase down the source.

    And if I'm wrong and it's not related to food chain, then we've just encountered yet another new pathogen... It really feels as though the pace of emergence is accelerating.
    • by jabuzz ( 182671 )

      You have not been allowed to feed "cattle cakes" as you put it to cattle since 1996 in the UK. The whole process was completely banned.

        And the reason for that is almost certainly the link to BSE.
