Poultry and Fish Farming Danger


Photo by Jina Lee

Once in a while a comment left on a post here gets me thinking about something I probably should know more about. An example from yesterday is comment #14 from Paul on this post about raising cattle indoors.  While I don’t agree with everything Paul says, like most well thought through comments, there is a lot to think about in there.  What really got my attention though was his reference to how some Asian farmers raise their chickens and fish, some of which probably gets exported to your local supermarket.

I had heard of what he describes once before while reading about the avian flu scare of a couple of years ago.  But I never followed up on it and have not seen anything about it since.  Basically what Paul refers to is this….  Some farmers in Asian countries commercially raise chickens in cages suspended above the ponds in which they raise fish like Catfish and Tilapia.  I did some research and there is not a lot of information about this practice, and much of what there is comes from avian flu experts worried about disease, not food safety experts.  Here is a PDF explaining the connection between fish farms and avian flu and another link discussing catfish farming practices in Thailand.

Farmers raise poultry and fish like this so that the chicken poop falls through to the water to feed the fish.  Cheap fish food and effective use of limited farming space I guess.  Now, maybe chicken poop is a healthy food for fish, but it seems a bit disgusting to me.  But wait, it gets better.  When the fish are processed for export to the human food supply, the residual guts, heads, etc. are then fed back to the chickens…. who then poop the digested fish guts to the next generation of fish who, upon harvest, supply the chickens with more food.  Then when the chickens are harvested, the waste from that process is fed back to the fish.  Common sense tells us that this sort of closed system could be very dangerous to the food supply.  I know I would not want to eat those fish or chickens!

Of course, as I explained here, I don’t eat farmed fish anyway so I am out of that closed loop but that does not make me any less concerned about the questionable practice.  Plus if the bird flu experts are to be taken seriously this method of farming creates real potential for human disease.  What do you think?  Do you ever eat imported, farmed fish from Asia?  Do you even know where your Catfish or Tilapia comes from?

I think your last question is probably the most relevant. How much of what we eat comes from unknown sources? When we buy anything that’s been processed in any away, how can you really be sure of the source, and even if it’s listed, how can you be sure of its accuracy? I’ve heard before that when a test was done on fish sold (I believe in supermarkets and restaurants) to the public, quite a high percentage of it was not even the type of fish it was supposed to be.

Gosh, the fish picture creeps me out! Now, I do not ever want to eat fish. I guess we would be shocked, if we knew how our food is produced before it gets to the stores.

I watched a documentary here some time ago about fish farming in Asian countries. Some of the rice farms have been converted to fish farms because the returns are much better, but they are overpopulated and there is not enough water flowing in and out of the pools to keep the water fresh. Added to this they use chemicals banned in Australia to stop the fish from getting diseased. Needless to say, I only eat Australian fish, but as we are in the Asia Pacific region, who knows what some fish mongers try to pass off as Australian!

I don’t think Cattle fish and Tilapia are dangerous to eat. The only thing they are not safe to eat is when there id the so called red tide. But mostly Tilapia are raised in the ponds rather than in sea.
Poultry like chicken are only not safe if they are being exposed to flu and other aerial sickness.

Such a shocking information for me! I used to eat farmed asian fish but now on I’m gonna erase it from all my menus. Bloah, it is really disgusting, that they are feed with chicken poop.

This news is really shocked..Very disgusting this kind of fish are going to feed to the chicken..

This is so disgusting. Here in Australia they have to label where fish comes from in supermarkets, seafood shops etc but still we are at the mercy of the honesty of the shops. As Binky said , what about restaurants? We have no real idea what goes on behind the scenes of so much of our food. There was a big Current Affair episode once revealing how widely spread the fish substitution racket was. We just never really know for sure. That’s what I love so much about my homegrown veggies. I know where they’re from & what’s been put on them

Hey Tony – You, Jan and Binky are right on the identification of what is actually being sold. What is sold as “Red Snapper” here in the US can be any of a number of other less desirable rock-fish species. That particular switch does not necessarily make what is labeled as Snapper unsafe to eat, but it should be illegal anyway to do it.

Hi, I live in Indonesia. In some small local farmers, they do use poops as food for catfish. I almost never eat catfish again, disgusting indeed. While tilapia, they mostly use the pellets as food, so no problem to eat it.

For the export quality fish, farmers are required to meet HACCP (Hazardous Analysis for Critical Control Point) standards. Usually, the exporter will do HACCP test of fish they would buy.

The way they raise catfish and Tilapia is really unbearable. The food authority should never allow such set up in raising fish and chicken. I know about chicken poop being a fertilizer but a feed to some fishes, it’s really a no-no. I don’t really know about this issue until now so thanks for sharing this information. It makes me aware about things that’s happening in some countries in Asia.


11 Gregg Evans

Well, it’s really unbearable. But I’m just curios, can it cause any human diseases? Anyway, you cook it first before eating.


12 Patricia

Don’t know about that, Gregg but the fact that those fishes ate chicken poop will probably cause bacteria that could lead to illness or such to the fish that we can’t see. Anyway, its just my opinion.


13 Gregg Evans

Well yeah. It’s a big possibility though.

This is a great post. My family and I live on an island in Thailand, and we only eat fresh fish ( and we don’t consume any other form of meat). All of the meat here is raised free range or at least close to it. When we lived in Korea there was also a lot of fresh fish and seafood, but the chicken situation was the same, and actually US beef industry folks had come to Korea years back to increase importation of poor quality factory farmed meat and poultry. Thus their meat consumption went up and their small local farms lost money. It’s a sad situation.

Hi Will,

Yucky! This is indeed disgusting! I hope McDonald’s chickens are not eating same stuff as this lol!


16 Rob

Britain was badly affected by mad cow disease which resulted from similar unnatural practices.
If its not natural, it’s not right!!


17 David Crew

Good that here in our place, we only have here fresh fishes from open seas vend in the wet market.

What do you think fish eat in the wild. Do you think they are fed pellets. No, they eat whatever they want to eat. Catfish, Tilapia, Prawns are bottom feeders. They eat the crap on the bottom. The nutrients that are within chicken manure is 100% vegetable compound. If you are still sickened from the fact that chicken manure is vegetable waste and the fish are consuming it, with it being a healthy alternative to the garbage, processed foods and waste being dumped into our water sheds and these fish consuming that. I would be a lot happier knowing that my fish was raised being fed a feed that originally was not a processed, man made concoction of who knows what.
Lindsey hope you are not serious about Mcdonald’s. That’s not remotely close to being food. If you need that stuff to survive you have no room to talk about what a fish is being fed.
Just look at what KFC, thinks is chicken “oh thats right, they changed there name from Kentucky Fried Chicken to KFC because the government wouldn’t allow them to use the word Chicken in there name” as it isn’t chicken they are serving you.

john you just nailed it, I wander what they think fishes actually eat in the wild.? I also think its natural food for the fishes and poses no health risk to humans and beside chicken diseases are not pathogenic that means they can not be passed to humans except for the bird flu of which well cooked birds possibly kills the virus.
