herbicides: pelargonic acid (Scythe) and acetic acid are famous examples, but glyphosate (Roundup) and imazaquin (Image) have higher LD50s than table salt. insecticides: Bacillus thuringiensis Cry proteins (used both in organic agriculture and in Monsanto's Bt lines), RNAi

Having a higher LD50 than table salt does not establish that a substance does not have serious long-term effects even at low doses.

no, I didn't say it did. But there's also no convincing evidence that either of the synthetics I mentioned does cause negative long-term effects (let alone serious ones).

Another comment has already pointed out that until we see the underlying study we can't be sure that this press release is really important. I note that the claim "In the largest study of its kind, an international team of experts led by Newcastle University, UK, has shown that organic crops and crop-based foods are up to 69% higher in a number of key antioxidants than conventionally-grown crops" doesn't tell us anyt…

The evidence for molecular intervention (almost always with positive outcome) of antioxidants in the form of phytochemicals (the ones that have been around us for millions of years) in the biochemistry that occurs in animal bodies is overwhelming as a search in the literature will tell you. I've read hundreds of papers reporting such results. No one talks about proof in science but this is at least indicative though…

What's a good review article on the topic? What kind of underlying studies contribute to metaanalysis on this issue, in vitro studies of direct application of the antioxidants, or carefully controlled in vivo studies of consumption of different kinds of foodstuffs? (I did the expected Google Scholar search back when this thread was more active, and I'm not seeing many citations to reliable secondary sources even now in this thread.)

The principle of least harm. But I was replying to someone who said they live in Central Arizona. Ironic that Atrazine is produced by a Swiss company and can't even use it in their own country.

When was the last time Agent Orange was dropped on an American everglade? (Trick question..)

While I see what you're driving at, AO wasn't dropped on Everglades and then banned.

The point is this: America cares less about the harmful effects of big-corp-produced substances than Europe does.

I'm not sure that is the reason they won't use the restrooms nor that we are actually hearing the specifics of the rule nor the reason for it or if it is anything more than internet rumor (wouldn't be surprised). People like Michael Pollan are ideologues (a good writer...I have read "Botany of Desire") but you have to take some of their views, particularly on science, with a grain of salt. Something like Micheal Moor…

I could not find language supporting a "private restroom" requirement after about 30 minutes of Googling, but it appears that FDA meat processing regs may require full-time on-site inspectors. Considering that slaughterhouses process the entire animal, and thus have to deal with whatever happens to be on the hooves or skin, or inside the viscera, it may be that a separate restroom is actually a method of reducing the…

Ha! I just made the same search and my comment was the top google result.

At any rate, this blog post provides the quote in question, from page 229 of "Omnivore's Dilemma" though it turns out it's the USDA, not the FDA that is mentioned.

http://www.businessweek.com/smallbiz/running_small_business/...

Here's the quote: "The problem with current food-safety regulations, in [small farmer Joel Salatin’s view], is that they are one-size-fits-all rules designed to regulate giant slaughterhouses that are mindlessly applied to small farmers in such a way that “before I can sell my neighbor a T-bone steak I’ve got to wrap it up in a million dollars’ worth of quintuple-permitted processing plant.” For example, federal rules stipulate that every processing facility have a bathroom for the exclusive use of the USDA inspector. Such regulations favor the biggest industrial meatpackers, who can spread the costs of compliance over the millions of animals they process every year, at the expense of artisanal enterprises like Polyface [Salatin’s farm]."

I've never heard of this. Do you have an actual source?

Only primary sources. Pick a few chemicals, find their LD50 from a MSDS, find their application rate. Run the numbers. An organic fungicide: copper sulfate pentahydrate (aka CuSO4) A non-organic fungicide: iprodione (aka Rovral) LD50 of CuSO4: 472 mg/kg (rat) [1] LD50 of Rovral: 2g/kg (rat) [2] So straight up, the organic is four times more lethal to mammals. But that is just the beginning, because you have to use a…

Perhaps I generalized a bit too much (I suppose I should not have commented when I was dead tired...) However, the USDA does in fact allow non-prohibited chemicals to be used on USDA certified organic produce.

No, we just don't have the privilege of enjoying luxury goods like organic food for every person.
