I buy organic and non-organic teas side by side quite often from vendors that offer both...and the organic teas have never had problems standing next to the inorganic in quality. The organics can be slightly more expensive...but that´s just because the certification itself is expensive...the farmers get the bill for the tests to confirm that their teas meet organic standards and that gets passed on to the consumer. I don´t really mind paying for the testing when I buy organic.

Really the only reason why I don´t buy all organic is that the variety is still a bit limited and also I think that higher grades of tea pesticide use should not be such an issue as with lower grade teas. It´s actually quite common for farmers that focus on premium products to use organic farming methods and not seek the certification simply because certification is expensive. They will also have some product certified and sell it at a higher price than non-certified product from another batch grown on the same farm with the same techniques. This applies to both tea and non-tea organic products. Sebastian from Jing Tea Shop has talked a bit about how this applies to tea...and I´ve worked in an organic grocery store where I learned quite a bit about organic certification and where food comes from.

Around Christmas and Thanksgiving they got a LOT of turkeys in stock...some organic and some free range. The organic turkeys were very small and expensive, the free range turkeys quite big and not much more expensive than conventional factory farmed turkeys. The inside scoop is that both the organic and free range were from the exact same farm, they were raised and fed exactly the same way. The organic ones had to be culled earlier so they could be tested before thanksgiving is why they were smaller and the testing raised the price a lot. So non-certified was fresher, larger, and a better price but both were raised in exactly the same conditions. :shock:

That´s an extreme example though the extra cost, time and effort involved in getting vegetable products such as tea organic certification is certainly an issue...and it´s why I feel pretty good about buying non-organic tea of high grade from trusted vendors.

Theoretically, tea grown with good and ample organic fertilizer tastes better (this has been proved by some tea farmers, especially those who care to research and compare). But in reality, some producers who grow organic tea without investing 10 times of labor in fertilization. As a result, the tea is pure organic but didn't receive enough fertilizer. That's why it's not uncommon that people find some organic tea not as tasty as inorganic tea. If an organic tea isn't tasty enough, of course it's not because pesticide is missing :mrgreen:

The obvious question for me is whether being above the legal limit is actually bad for you.

Chiang Yu-mei, a senior technical specialist at the city health department, said pesticide residue in tea can cause nausea and vomiting, while increasing the risk of liver problems.
so....yes

That doesn't actually follow. Chiang Yu-me says nothing about the amount. I don't doubt the statement but it says nothing about the amount. Also, a city health department official hardly an ideal expert.

I think it's the general rule of public health that if a chemical is proved (or suspected) to be harmful at certain level, than the legal level should be controlled to be 1/100, 1/1000 or even much lower than that tested level. Some chemicals don't kill, but we rely on our good old liver to get rid of them. If we allow ourselves to be exposed to too much harmful chemicals (many food preservatives are of this kind), we are in one way exhausting our livers. This is actually talking about the least harm of some chemicals. Then we should also consider that some chemicals accumulate in the body and can't be removed through metabolism (DDT a typical example).

But I do think tea of decent quality (especially with small plantation cultivation) is safer than most food we consume daily :mrgreen:

A list of Taiwan's maximum residue levels can be found in the last document listed at http://food.doh.gov.tw/english/Acts_Reg ... safety.asp. That will at least give you an idea of the levels that were exceeded in the tea; if you then look up studies of those pesticides' effects, it may give you a better idea of whether exposure to them at above the levels listed in the document is bad for you.

Gingko, since I drink what I consider to be decent quality Chinese and Taiwanese tea from trusted sources daily, I hope you're right. But I think that even smaller, well-managed farms can't necessarily escape the environmental problems of the areas surrounding them. Still, I agree that the issue and risks are not limited to tea, and that we're probably exposed to worse in a lot of the food we eat.

Less than 10% is not that huge and in Taiwan
10% is huge given all the untested teas that were NOT pulled.
Actually, the percentage could drop if they did test more teas and they weren't above the legal limit.

I still don't think 10% is a huge % because I suspect in China that it is much higher than that. And, considering how large Taiwan's tea trade is, I'm surprised it also wasn't higher. I'm not condoning this at all. I think it's criminal. It's a real matter of concern to me.

Regarding the other matter of taste between organic and non-organic teas, it was only on a Japanese tea site that I saw this argument raised in DEFENSE of growing tea with non-organic fertilizers. I still think it's bull...

I agree that without well-established laws and regulation, we can never be sure even small farms are free of contamination. I think the view of smaller farms are better and safer is generally from cost and benefit analysis. In the past year a few small farmers told me they skipped their summer pesticide spray, not because they want to sell organic tea, but because it was too costly in the chemical itself and in labor.

Besides, if you have a plantation like this one in the photo, there is no way you want to spray anything on it and it's nearly impossible anyway. :mrgreen:

Presumably the tea being sold at "Taiwan Handicraft Promotion Center chain store" is from Taiwan. ;)

It's not pleasant to think about, but potential exposure to harmful chemicals (not just pesticides) from tea is reality and, in my opinion, deserves more attention and acknowledgment. (Especially when many tea drinkers think they are doing something positive for their health.) There's no reason to assume that tea-growing areas aren't subject to the same-- and often very serious-- environmental issues seen elsewhere. Whether and how such issues can be alleviated is a gigantic question; in the meantime, there should at least be a greater awareness of what we may be exposing ourselves to.
Taiwan has definitely had incidents of contaminated tea but I think it's been relatively rare compared to the number of incidents from mainland China. In at least one case, tea labeled as native Taiwanese oolong that was contaminated with pesticides was actually a Vietnamese oolong. It was labeled by customs as native Taiwanese tea after they were paid off by the importer.

I agree there's not much more contradictory than drinking pesticide-saturated tea for health benefits.

Japan is much better than China in this regard, and in my opinion they significantly beat Taiwan as well. I will purchase Japanese tea from many Japanese vendors without worrying about safety, but for Taiwanese teas I use only one regularly (Hou De). For Chinese teas, I also use Hou De but purchase mainland Chinese greens from Jing as well, since Hou De doesn't carry them.

These comments apply to the safety of the tea, not the taste as I find the better teas from all three countries to be exceptional in this regard.

When I ordered my first lot of organic sencha I didn't know what to expect based on the negative comments organics have received on many forums. It took a few tries to get used to the taste and how to brew it, but I've been drinking organic Japanese tea ever since. I have no issue with drinking non-organics, but the organics get undeserved negative comments about their taste and quality that I strongly disagree with. In fact, I have found the leaf quality of deep-steamed organic sencha to be far superior to the non-organic versions. The leaf is much less damaged and has far less bits than the non-organic fukamashi's I have tried.

Are there any evidences that the teas sold by Hou De and Jing are less infected by pesticides than others?

The only evidence would be testing. I would think if neither vendor mentions that is organically grown but no certificate, then you will be drinking teas grown with pesticides. This is why I buy Taiwan teas from Teafromtaiwan. If you ask them, which teas are grown organically, they will tell you, but, none have certificates. I'd much rather take my chances with this kind of info than with none at all.
