Chinese Cooking Oil “Made from Sewage”




The news that a tenth of all cooking oil used in China may be made from recycled sewage and laced with toxic contaminants has stunned China.

Originating from a report on a state radio station, the news that “Chinese are eating 3,000,000 tons of ‘recycled cooking oil’ each year, but it is 100 times more toxic than arsenic!” spread throughout China in a matter of days.

The cooking oil is apparently “recycled” from raw sewage taken from sewers and elsewhere, which is heated and filtered. After filtration the liquid is transparent and free of particulate matter, and can be rendered into cooking oil.


Fears over the toxicity of the recycled oil are high. Significant levels of aflatoxins have been detected, a poison said to be “100 times more toxic than arsenic,” and known to cause growth defects in children and cancer.

Viral and bacterial contaminants are thought not to be a problem, assuming the sewage-oil is properly boiled in preparation.

Despite the obvious hygiene and safety problems of using treated sewage in cooking, its usage is thought to be widespread, as the “recycled” cooking oil is all but indistinguishable from normal cooking oil, in all but one aspect – its price.

It costs only 300 yuan ($45) a ton to manufacture, half the price of regular oil, and it is said to be common use throughout China – estimates are that it constitutes a tenth of all cooking oil used in China.

Chinese food safety regulators, such as they are, launched an immediate emergency investigation, although it is not clear if they actually previously approved the activity.

China’s record on food safety is of course already utterly abysmal, but if as widespread as reported this could turn out to be the most damaging scandal to date, as cooking oil is an integral part of food preparation in China.

Nations importing cheap cooked foodstuffs from China may also be concerned that they have been inadvertently poisoning their children by trading with a nation in which regulation and business ethics are all but unknown.

    Why the fuck does China do these things?

    Seriously. Who looks at cooking oil and says "Hey, this would be cheaper to make if we used Treated Sewage instead of normal ingredients? This takes a step beyond "Bad Business Ethics" and into "Cartoonish Supervillainy".

    So I guess the only thing one can say about this is, well, buy your ingredients at a premium, and don't eat at the cheapest fry-stands around.

    Also: "Mmmmm, e-coli!"

    Consider this... One bowl of rice feeds one person in US, while the same bowl is shared with seven people in China.

    As China is embracing capitalism, the gaps between lower class and upper class starts to widen. Higher demands from the rich, plus food shortages equals high prices for simple good. The poor have to come up with ways, however crude, to get the same products.

    It's not China as a whole that's doing this. That's why the officials are shutting it down.

    because it's not sewage. it's re-used oil, essentially.

    Bullcrap. Allow me to put it to you simply: would YOU eat cooking oil that was made like this? Hell no, you wouldn't!

    Now, cooking oil that DIDN'T go into the sewer? Okay, I can deal with recycling that, after the MULTIPLE filterings that are done on it in the United States, it is reusable!

    HOWEVER, not when it went in the fucking sewer!

    There are very few sources on this, but there are multiple, and some precedent from a few years ago too... [ and Territories/China]

    So let me get this straight.

    It costs half the price of competitive cooking oil.
    It's estimated that 10% of China uses it.

    Would someone care to point out the glaring flaw in that logic?
    Anyone? At all? Bueller?

    Those who said you would never eat another "made in China" product, chances are you may die from starvation quicker than food poisoning.

    They'll just shell out more money for the non-MiC food, plenty from elsewhere. Obesity maybe but they won't starve.

    This news is about Chinese government find and destory the undocumented oil factory.
    This factory is not registered with Chinese government, so they dare use this things to make oil.
    Not all factories are like is.

    Well, *theoretically*, it should not be a problem in terms of biological contaminants, as they -- according to the story -- use high heat in the process, which should kill off anything nasty.

    The biological problem I see is re-contamination by little droplets which spattered up and didn't get the full high-heat treatment.

    The BIGGEST problem I see is that Chinese manufacturing companies will be dumping all sorts of toxic chemical contaminants into the sewer system, and the "high-heat" process does NOTHING to remove them.

    Remember the cardboard rice cakes? They had no rice just cardboard. All the stuff prior and since I don't think I even want any more pets since they all died of 'something' abnormal and strange for conditions. I am all wracked up too like my kidneys are hard from something. The only thing I can see that China can do worse than it has been is using the cook book from the movie about aliens "to cook Man" or whatever the name was. Next thing we will see is, south asian, north asian, russian, american, latin american, on cannabilistic food processed and served by China. It can't get any worse.. can it?

    the cardboard thing was a hoax, dumbass, and this isn't sewage- it's waste oil.

    if you could make viable oil out of sewage for that cheap it'd be burned as fuel, dumbass.

    Sometimes things aren't considered as hazardous as it is. Such as garbage collectors wear gloves to collect garbage, shouldn't you also wear gloves when you dump yours?

    I guess most of you must be too young to remember the aflatoxin scandal back in 2001 when it was found that many brands of US peanut butter contained aflatoxins at well over the permitted levels. All peanut butter contains aflatoxins to some degree or other, it's pretty much unavoidable. The thing is though, are aflatoxins really as bad as people say? The science linking them with liver cancer is still a bit inconclusive, and has only been definitively established in the case of people already suffering from hepatitis B.

    I know this may seem a little shallow but this discourages me from buying Chinese food products from the store, i used to buy Chinese cooking oil ans even if the brand i buy does not use raw sewage, i am not buying it anymore from here on out.

    Just read this on wiki about aflatoxins;

    "... humans have an extraordinarily high tolerance for aflatoxin exposure and rarely succumb to acute aflatoxicosis."

    That's why they got away with it for so long...

    On another note, I'm going to be sick. My diet is (was) primarily imported Chinese food, and now I read this...

    Well, in China they're also put in prison, just that there are too many people to replace them. On the bright side, their death penalty, when used, takes care of some people permanently.
