Bone/ Blood Meal and Mad Cow Disease
Does anyone know of any research that has been done on the potential for
contracting mad cow disease from using bone meal or blood meal as a soil amendment for veggies or herbs. That is, assuming no direct contact with the stuff. |

... Does anyone know of any research that has been done on the potential for contracting mad cow disease from using bone meal or blood meal as a soil amendment for veggies or herbs. That is, assuming no direct contact with the stuff. Human CJD has been attributed to eating beef contaminated with brain or spinal cord material (where the harmful prions live.) If you do not eat garden bone meal, you need not fear it as a disease vector. -- Don Phillipson Carlsbad Springs (Ottawa, Canada) |

That is, assuming no direct contact with the stuff. Four cases in Great Britain were not traceable to any meat eaten, but all four were inveterate gardeners who used bonemeal. It is believed they inhaled the initial prion infection while spreading bone meal in their gardens. Agricultural lobby & spin doctors have hired scientific spokespersons to state pretty much "there is no evidence that BSE can infect humans by inhaling bone meal." The guys hired to say this usually have five or six degrees in science, but never did any actual studies, & get paid by Agribusiness which uses bonemeal. It remains that the four cases in England have never been explained by any alternative theory, since those four gardeners had not been exposed to infected meat. It is also not being studied to what degree the BSE prions can be absorbed, unaltered, into edible tubors & plants --thus entering the food chain even for vegetarians. It is theoretically possible, but it isn't being studied, so there is no evidence one way or the other. The prions have reached the bone meal product by several methods. While it is no longer legal to put infected sheep & cattle meat in feeds for dogs, cats, pigs, or cattle, it is still legal to make a rendering product from waste meats that are not to be used as animal feeds. BSE infects game animals in the United States, especially elk, & these end up at rendering plants as roadkill. They also render sheep, the most commonly infected farm animals in the United States. Lastly, while it is widely believed that chickens cannot be infected, some scientists speculate that chickens have "safely" eaten prion-infected feeds merely because their lifespans are too short for the infection to injur them -- but the prions could nevertheless be in their brainstem & spine, & rendered chicken meal could also be a source of the prions. And the rendering plant industry is self-regulating (meaning largely unregulated). On the rare occasion when anyone ever checked to see if self-regulation worked, the vats obviously had everything from zoo animals & roadkill to dog & cat carcasses from animal control & run-over racoons, with wildlly inadequate methods of monitoring which end-product batch gets labeled liver meal or chicken meal or beefmeal allegedly suitable to feed even pets -- & you can bet they care even less what goes into their garden-grade garbage. Not much in the news was an American recall of Canadian pet foods found to be contaminated by BSE prions, but if anyone thinks they're more careful in say Milwaukee than in Alberta, they're kiddin' themselves. Because the risks of bone meal in garfdening is not being studied for publication in peer-review contexts, it is possible to say there is no definitive evidence of risk, & fail to mention no one is looking for the evidence because vested parties fund such research & can pick & choose what suits agribusiness best. And those four British cases remain a haunting answer to any Agribusiness spin about it all beikng unproven. One of these victims reportly "never wore a mask & used to grind up the soil & make a big cloud of dust" when adding bonemeal to his rose garden, & was exposed to it on many occasions over a great length of time. The majority of Britain's human cases ate at MacDonalds -- MacDonalds was the sole source of the contaminated meat! -- but four victims were evidently exposed only to bone meal fertilizers. That fact doesn't qualify as a "study" so agribusiness dismisses the cases as unproven, & will certainly never admit how extremely likely it is. In a garden that is not used for harvested vegetables, & if a gardener wears a high-end face mask while spreading bonemeal (not one of those worthless felt paper mouth guards), the possibility of risk would seem largely to be mitigated. Not that I've ever seen a gardener with even one of the worthless felt-paper face guards which stop nothing from going up the snout, let alone an industrial grade real-deal filter mask. But even if it were reasonable to assume it is safe to breathe in bone meal while fertilizing the garden, I would not use it. I do not want to look at my gardens & have to think, "I've sprinkled rendered animals all over that." -paghat the ratgirl -- "Of what are you afraid, my child?" inquired the kindly teacher. "Oh, sir!

opined: Does anyone know of any research that has been done on the potential for contracting mad cow disease from using bone meal or blood meal as a soil amendment for veggies or herbs. That is, assuming no direct contact with the stuff. I don't know that data, but soft rock phosphate is far better for soil than is bone meal and seaweed is far better for soil than is blood meal. ....as an aside.

That theory has not been publicised in Britain afaik, so could you provide a source for it please? Janet. The most recent [ West of England Medical School-pub. May2004] research suggests that eating meat might very well have little or no relevance~~ the prion being capable of withstanding autoclaving of instruments. The work has shown that removed tonsils and appendixes from healthy patients show a significant [but small] proportion having the prion. The proportion, when extrapolated, means there are several thousand carriers of vCJD who could have contaminated others, or been contaminated, via contact with affected, but supposedly sterilised, instruments. It is not known if these will eventually succumb to vCJD or even if this is 100% related to BSE. I suppose I should take precautions when using bone meal but I'm always too busy to bother. Others suggest that if I did get 'mad cow disease' they would notice little difference~~and they are my friends!! Brian. |

No single source of infected meat was identifiable. By no means a joke. Deaths from e-coli & mad cow is why they are so often called McDeath or McDisease, serving Big McBrain & McPoo burgers. Most or all the UK cases were from meats processed by McKey Food Corporation under contract to McDonalds. McDeadly was where victims purchased the greater percentage of beef in their diets. McDonalds became McLibel trying to sue people into shutting up about it; they didn't care if they won or lost the suits, which were intended to be costly for their foes. The suits were defined as "strategic lawsuits to stop public activism" & succeeded in frightening even news agencies into mentioning it, because short of a doubleblind independent study (which was never going to happen) no proof could ever be proof enough, & McLibel would sue & sue & sue & become the biggest nuisances on earth. Newspapers would rather have McDonald's advertising dollars rather than be the target of another of McDonald's Strategic Suits Against Public Activism, so they won't harp on the connection. But somehow in their suit-happy mood McDonalds never had the nerve to sue Eric Schlosser who documented McDonald's role in spreading diseases to people, because that's stuff that won't help them once it is quoted thereafter from sworn court testimony. but four victims were evidently exposed only to bone meal fertilizers. That theory has not been publicised in Britain afaik, so could you provide a source for it please? It was reported on Dateline in August 20, 1997, that four victims in UK of the human form of Mad Cow were not meat eaters, but had been exposed to bonemeal in their gardening practices. It was also in numerous newspapers at the time. The Dateline report had the daughter of one of the victim describing her father in his rose garden stirring up a veritable cloud of bonemeal dust. Doubtlessly it was in UK newspapers just as commonly at the time. But public memory is short, & when a new Associated Press article does appear as a reminder (such as by Rukmini Callimachi this past December, in the wake of a new mad cow scare) who really reads the newspapers these days? Callimachi reported that only THREE non-meat-eating gardeners died, but previous articles always say it was four; there's always absolute agreement they were gardeners who used bonemeal, & had no other possible point of exposure to the deadly prions. In consequence of these facts, the British Royal Horticutural Society recommen ds that bonemeal users never use bonemeal without a facemask. The utter uselessness of the sorts of masks you can buy in nearest hardware store, unfortunately RHS failed to note that. After the mad cow scare last year here in Washington state (thanks to infected cows brought in from Canada making it into the human foodchain) a number of safety measures were put into place that never existed before, & which even now have no enforcement system. The recalls included bonemeal products using cowparts, & also soaps. One federal inspector said that there were so many niche markets for the secondary leavings of diseased cattle that it was impossible to recall all of it. Several distributors of this deadly garbage "voluntarily" withdrew bonemeal & tallow products from the given time-period of BSE known to be in the product chain, but volunteering was just a trick to guarantee the government would not in the future harrass anyone with any new laws with teeth or enforcement of any kind. It remains a self-regulating industry, & cleaning up their act is strictly a matter of public relations. -paghat the ratgirl -- "Of what are you afraid, my child?" inquired the kindly teacher.

"Will" wrote According to my son, a medical microbiologist with a keen interest in BSE, your stuff is spot on. May I respectfully suggest, Will, that regardless of your son's opinion, a discussion of a disease acquired by eating at a restaurant is off-topic on a gardening newsgroup. The original question, whether bonemeal fertilizer is a threat, is more related, and as usual Paghat's response is fabricated nonsense. |

The original question, whether bonemeal fertilizer is a threat, is more related, and as usual Paghat's response is fabricated nonsense. Actually it's dead-on on-topic that gardeners should know the evidence of four out of 50 deaths effected gardeners through use of bonemeal, the rest through eating at Mcdonalds. Those are FACTS and only blind-with-head-in-shit-pile fools won't even consider the facts of the matter. It's also dead-on on-topic that the Royal Horticultural Society recommends never using bone or blood meal without wearing a mask because of the risk of BSE exposure. Even the type of head-in-shitpile fool who won't believe in reality should be able to tell that's on-topic.
