DE (food grade?) good or bad

[collie1470]

Briza also provided the MSDS, which would have to be updated as new problems with it surface. Sore nose and throat, and congestion are unpleasant but not serious. CPD is serious, but it's not cancer.

(Edited for spelling, because my phone is ridiculous)

So, the MSDS provided was updated in 2011. If it was proven carcinogenic since then, there will be an updated MSDS publicly available. So, on to search for it.

Chickengeorgeto is right. The MSDS was updated (this is a different brand it looks like, but the idea is the same). It is carcinigenic.

Learn something new everyday. Well, I'll never be dealing with DE again. I don't have a respirator that filters particles anymore. The MSDS doesn't lie. Though it doesn't mention dangers from ingestion, it's easy to accidentally inhale a powder.

CPD? Do you mean COPD?

 

[collie1470]

I just contacted my dog's breeder to warn her about the carcinogenic properties. Studies and anecdotes can vary, but an MSDS doesn't lie. And cancer is a serious risk

it said chronic pulmonary disease, not chronic obstructive pulmonary disorder. Though I imagine they are pretty much the same, if not the same.

Notice that this would be "pool grade".... That's why the emphasis on FOOD GRADE DE...3% or less is the limit on FOOD GRADE DE....38% is too high to be food grade. Helps to look up the right mineral...or in the case of POOL GRADE DE, the wrong CHEMICAL.

Edit to add correct MSDS for FOOD GRADE DE

Perhaps you should open and read this link before you start calling people who you've never met a liar.

This references Pesticide grade DE. You may be able to dice up the difference in your mind about DE (which is a desiccant or drying agent) used in cat litter, oil dry, and to filter industrial fluids, and so called food grade DE. That still isn't proof that any type of DE will do squat to kill internal parasites or insect pest, like Fire Ants.

I gave you evidence from a disinterested scientific source that DE is far from being as safe as mothers' milk, please reciprocate by providing scientific (as opposed to antidotal) evidence that DE will kill internal parasites found living in the bowels of chickens.

I have never said that it kills parasites inside the body. I even specifically said that I did not advise it and have posted links to the mechanisms of action(towards pest control) of DE previously in this thread. I have also stated that it does not work well on roaches. It depends on the exoskeleton of the bug in question. No, it does not work on ALL bugs and it does not work instantly(it can take up to a week in my experience with mange on a dog). However, it is a useful tool to have as part of a balanced pest-control regimen. I have also stated that I began using food grade DE(which is a desiccant) as a last resort against insects that could not be controlled by other means. I live in an urban area where pesticide resistance is unusually awful. It may very well be a person's only resort in controlling a problem bug and it does no good to scare them away from it by saying it causes cancer when food grade DE does not. It IS a messy product and I generally reserve it for outdoor use or when other control methods have failed. I have provided plenty of evidence from highly regarded regulatory agencies. My links are embedded so it may be that you do not recognize them. They are the blue text that shows up in my posts.

Edit: I am exclusively talking about FOOD grade DE. POOL grade IS toxic.

Now I think you're just making that up or talking about the pool grade DE. As for the MSDS sheet, read this one. It says it right on it that it is NOT classified as carcinogenic by the National Toxicology Program or by the World Health Organization's International Agency for Research on Cancer. The only issue with it is chronic exposure to the airborne particles above established limits as with any dust particles of that size.

You may not like DE but you shouldn't lie about it. Neither the FDA nor the EPA have anything to say about DE and cancer after intensive searches of their respective websites. DE is actually a GRAS and used in processing of food. It's also under the livestock feed additives as an anti-caking agent so odds are, your animals are already eating it if you give them commercial feed.
