Climate science solution: bread made with cockroaches

Let them eat cockroach bread. From the “ew! just ewwwww!” department of climate salvation, comes this idea that’s sure to catch on with people who are really concerned about reducing their carbon footprint. Forget steak, forget Soylent Green, it’s roach-bread!

Looking for an easy, affordable way to get a high protein diet? Researchers of the Federal University of Rio Grande (FURG) in Rio Grande do Sul may have come across a crunchy answer, although it might turn your stomach; cockroach-laced bread.

Just like peanuts: ‘Tasty’ cockroach bread may feed world’s population in climate change era

The threat of climate change looms large, providing a unique set of challenges for the future, including how we will feed an estimated 9 billion people by 2030. One group of researchers in Brazil has proposed a different, stomach-churning solution. Cockroaches made into bread.

“They remind us of ches[t]nut or peanut. They’re really good and tasty, and (their presence) does not affect the flavor of the bread,” said Myrian Melado, a researcher at the Federal University of Rio Grande, as reported by AsiaOne.

The practice of eating insects, known as entomophagy, has existed for millennia but has been largely overlooked in the western world since the agricultural revolution.

However, as climate change continues to threaten the long-term viability of traditional livestock agriculture, scientists are once again turning to insects as a potential solution to world hunger both now and in the future.

“Insects don’t create waste. If we think of the amount of water we need to breed an insect, compared to the amount of it needed for cattle breeding, it’s infinitely less,” continued Melado.

Scientists have long played with the idea of switching to insects to meet our protein requirements but, so far, the market in the West has resisted the allure of fresh mealworms that taste like pumpkin seeds or protein bars made of crickets.

Can we assume that these will be free range roaches?

Positively NOT. These will be counter-top roaches. Now pass me the maggot mayo and the skunk bologna; I’m hungry.


Only if we abolish the FDA. Even raising cockroaches for reptile food requires cages, clean substrate, etc. Unlike cattle, you can raise a pile of these bugs in a 50 gallon aquarium and they the breed at frightening rates.
(Yes, I have raised two different types of cockroaches. I did not munch on them, ever.)


And organic

Rita Ryan



Ha,ha,ha, ha….thanks for providing my first belly laugh of the morning!!!!!


Who will Keith Richard’s talk to in the future?

No doubt cockroach based recipes will be all the menu items of the next IPCC conference?


That’s what’ll finally put paid to the IPCC–hold the next conference in Mogadishu, don’t provide mosquito netting, and load the menu with cockroaches. Make sure Leo’s there for photo ops!



Lol but no, the IPCC high rollers needs to have prime rib and lobster tail and caviar and Dom Perignon. Just slip in a little side of cockroaches au gratin and watch them flip out.

To make it 100% Politically Correct & Organic, be sure to use yeast supplied by Zoe Stavri!
If you don’t know who she is, and you’re not eating lunch, this is her claim to fame:




Double ewwwwwwwwwwww.


Could work great to fatten up the chickens, pigs, and maybe even cows. My mouth is watering already.

I remember seeing the…. oh, sorry, I’m heading to the bathroom…. urp…

Schmidt sandwich…


“Climate change” is not threatening livestock. Only climate kooks think the answer to adapting to the climate requires eating insects as a staple part of the human diet. Climate obsession is a mental disorder.


It is surreal that these articles continue to be pumped out on such a regular basis when the reality of what is happening is completely opposite. The warming of the last 150 years, plus the huge technical increases in our ability to grow food, (much of it powered by cheap fossil fuels), plus the fertilizing effect of increasing CO2 has put humanity well ahead of the hunger game. We haven’t even begun to apply the latest advances in farming around most of the world, so there is no end in sight to the improving food situation.
The reasons we still have starvation in some areas is mostly political, as governments and pseudo-governments get in the way of progress, human ingenuity and charity.


So much truth in all you say. Good job.

Destroying or eroding civilization away through draconian climate policy is an act of sacrificial penance for the secular religion of the warmists. Eating cockroaches would serve the same purpose.


Infinitely less water – really. I mean, who comes up with this crap. In order to use infinitely less you would have to start with cows using an infinite amount of water to begin with. All this does is make Maledo sound like an idiot

Steve Ta

Surely no water is infinitely less that any amount of water, however trivial. So maybe cows are fine – no way on knowing from this rhetoric.


This is the vegan loon lobby justifying their insanity as a “climate problem.” That’s what you get when your brain lacks essential fatty acids!


Never considered the lackes “essential fatty acids” idea. Interesting.


The PETOC folks will not like this.
(People for the Ethical Treatment Of Cockroaches)


I was thinking along the same line… Will PETA stand up for the cockroaches?

michael hart

Several years ago now I saw a website dedicated to the ethical treatment of shrimps, so it wouldn’t surprise me in the slightest.


Seems unlikely. I would think it would negatively impact donations to their organization.

Alan the Brit

The craziness never ceases, does it?

I gather that chocolate ants are supposed to be a delicacy. How about chocolate cockies?
Even supposing that Maledo didn’t really mean “infinitely”, and really meant “a lot less” then consider the amount of water used to raise one 500 kg bull, and the same amount of cockroach protein? But as bulls feed on (free) rain watered grass, and cockroaches feed on already cooked and prepared food, and hence food which has had (comparatively expensive) tap water used to prepare it, I would say that the balance may well be in the bull’s favour.
What sort of cockroaches? The small German or Striped cockroaches, or the large Bombay cockroaches? I suppose to be PC we should now call them Mumbai cockroaches.


My cockroaches ate dog food (the hissers) and raw potatoes and fruit (the cubans). I NEVER cooked for the bugs. They drank whatever water I put in the cage. They did have a waterer—sponge that was wet so the offspring wouldn’t fall and drown. I have no idea why anyone would use cooked food and filtered water. They’re BUGS.

Bjorsten Torkelson

For an extra zesty treat, try some Baltimore super roach tortillas.
Mm mm…that’s some good roach eatin’.
Note to self: Never, EVER, kiss a climate researcher from the Federal University of Rio Grande.
Best to never let them near your kids, either.
Those folks is crazy.


What about the overloaded grain bins and depressed prices for grain? Are we supposed to play along with the fake news of shortages from global warming just to make advocacy madness happy with their puppet strings?


A replacement for fish meal is probably most urgent. Farmed fish eat a lot of unsustainable fish meal, and insects could replace much of this. Per acre of land you get a much, much bigger yield than you do with crops, so there is no competition with food for human consumption.

The yield of fish per acre of land exceeds that of crops if you feed the fish with bugs? Amazing.

Thomas Homer

seaice1: “Per acre of land you get a much, much bigger yield than you do with crops”
Are you saying that insects have a bigger yield per acre than crops? What do the insects eat? If you’re supplying food from an outside source then the ‘per acre of land’ doesn’t apply.
Since Carbon Dioxide is the base of the food chain for all carbon based life forms, the yield per acre of any food source is limited by the rate of photosynthesis/phytoplankton. More atmospheric CO2 is required to increase the yield per acre.


Insects eat waste. There is lots of it about.
Michael – I meant the yield of insects, not fish.


if they allowed ALL bycatch that they DUMP instead to be utilised for fishmeal thatd be solving that problem and not fouling oceans(yeah i know..other wild fish get a free feed)
but I doubt all of it gets eaten real soon so theres some ukky bits floatig round for longer?


I used to work with a guy who was raised in the Canadian maritimes. We were having coffee one day and he had some ice cream. For reasons I can’t remember, I asked him, “What do lobsters eat?” He couldn’t finish his ice cream.
Some of the stuff we already eat, especially Chinese food, is way grosser than insects. It’s just a question of what we’re used to.

Tom in Florida

Keep in mind as you chew that a fast food all beef pattie does not mention what part of the beef is being used.


…that’s why I raise my own beef.
They’re miserable creatures sometimes but my revenge is envisioning them on the end of my fork. Medium-rare, I might add.

As long as it’s the tasty part, that’s all I need to know.

Rhoda R

Embrace kosher beef. I’m not Jewish but I do like some of their dietary requirements.


Embrace the roaches, and Chinatown can fire most of the health inspectors. Plus, extra protein!

Jeff Labute

I ate a scorpion-ka-bob in China. Was not too bad. tasted like a spicy rice-crispy square. The protein made me feel all pumped up. Would be less noticeable in trail-mix or something.

Mark from the Midwest

Kind of kills two birds with one stone for all those folks who live on the Upper West Side, they won’t need their exterminators any longer, with all the nasty chemicals, and they can brag about the latest in enviro-friendly cuisine. Yes it’s virtue signaling squared …


Franz Kafka, call your office.

Eustace Cranch

You are what you eat. 🙂

Will these be genetically modified roaches…will I have a choice between that and organic roaches…will the organic roaches be more expensive that the GMO’ed kind. Because I can’t seem to understand the up-charge on organic.
I’ve heard roach toast with a nice worm butter, taste like peanut butter and jelly…if you close your eyes. Of course when you close your eyes a lot things are better…I keep asking muffin why she closes her’s when she kisses me…


The researchers are just whistling the prevailing tune of climate change while polishing thier turd. We have had a whole lot of that going on for a long time. Recall that we paid for a scientist to place a shrimp on a treadmill.

Don K

For marketing purposes, cockroaches will henceforth be known as “Micro-lobsters”.

Has anyone ever seen anything like “However, as climate change continues to threaten the long-term viability of traditional livestock agriculture, “? What threat now to continue?


Governor Brown.

M Courtney

Cheap sources of protein shouldn’t be dismissed out of cultural hang-ups. Nor should they be forced on people, of course.
But this could be a good way of making nutrients.
Have you heard the theory that the first animal farmed by man was the snail? They are nutritious, self-contained for transport and eqsy to catch.
It made sense to me.

Pamela Gray

My two cats used to catch snakes till they got too old. Then they caught slugs. Apparently a tasty treat to a slow moving feline with no teeth.

harrow sceptic

I don’t think the French have progressed much beyond that

Gloateus Maximus

The size of some snails in Paleolithic shell middens suggests that cave people might have engaged in selective breeding, whether on purpose or by accident. It’s clear that at least they let the snails reach adulthood (at about a year) rather than eating them earlier. They could also have culled small adults out of the population, leaving the bigger ones to breed.


The “progressives” will have us all living in mud huts eating bugs “for our own good” if we let them. (While they tool around in their SUVs and private planes).


Bill Nye can eat this all he wants.
As for me – okay, I can put up with a lot of stuff, but this is the point at which I’m gonna break out the ammo and start linin’ vegans up against a wall. I believe I’ll have plenty of company.

Don K

I don’t think cockroaches are considered to be vegetables by those who care about such things. Personally, given a choice between bugs and kale, I’d probably go with the bugs — provided they were dead and not oversalted.


Still would taste better than kale…

Pamela Gray

Amen! Kale is nasty! Brussels sprouts times 100.

Brussels sprouts and kale are two of my favorite vegetables.
For those thinking that another Little Ice Age might be around the corner, kale is a great crop to plant, because it is a cool-weather crop, able to withstand extended periods well below freezing. I planted dino kale this fall, and it survived 6-degree F. plus an extended period of days in the teens.
Maybe the cruciferos-o-phobes have not eaten it properly prepared. You’ve got to start with FRESH, live food, … NOT the frozen stuff.
Fresh Brussels sprouts stir/steam fried in olive oil, a bit of real butter, a bit or salt and pepper …. is the way I do it.
Kale stir/steam fried in olive oil, fresh garlic, fresh ginger, a bit of salt, a bit of honey, and a bit of lemon juice … is the way I do this one.
Frozen Brussels do not accommodate this method very well. Boiling makes them mushy or hard and mushy at the same time, and the taste never compares to fresh.
… off to find some roaches now. (^_^)


I’d rather eat stall shavings than kale. Taste about likewise.

Don K

“Kale stir/steam fried in olive oil, fresh garlic, fresh ginger, a bit of salt, a bit of honey, and a bit of lemon juice … is the way I do this one.”
You omitted the final step: Strain out the kale and throw it in the compost or dry it and use as mulch. Pour the liquid over something edible — toast made from cockroach protein enhanced bread perhaps.

Oh my God, I love kale. And brussel sprouts.
Oo oo oo … and collard greens steamed so they’re still al dente. Yumyumyum!

Chop and fry a Butternut squash until it’s caramelising, chuck in some Kale (minus the stalks), salt, pepper and let the kale wilt down. Serve up with a nice medium rare Ribeye steak.

Kale needs to be chopped up thoroughly and then stewed for 45-60 minutes together with some smoked sausages. Bit of chopped onions and, if the sausages don’t already contain it, garlic. Salt and pepper as needed, again depending on how much the sausages already contain. Combine with boiled or fried potatoes. Very simple and very tasty.

Patrick MJD

Now now Griff, this is to save the planet don’t ya know.


Hmm! I think there is a point where the sacrifice has to stop…

Patrick MJD

You do not seem to be…please set an example.

Ed Bo

But does roach bread have gluten?


If it has wheat flour. Maybe not if you use the cockroaches for flour and leave out the wheat flour entirely.

Pamela Gray

I see nothing amiss here other than the clever way to get a grant to develop a profitable food source. These days new versions of shampoo are probably being developed using climate change hog slop grants. Here…pick my pocket. I don’t mind.

harrow sceptic

Re the classic statement “If we think of the amount of water we need to breed an insect, compared to the amount of it needed for cattle breeding, it’s infinitely less”,. Once again they are not comparing like with like. Yes a single cockroach will need “infinitely” less water than a cow, but how many roaches will be required to produce the equivalent food value of a cow and how much water will they use. One wonders are academics that thick or just bending the facts for their own ends


Cockroaches don’t require much water at all, even in large numbers. With 300+ hissers, I added maybe half a cup of water a day.


I would add that was only when the sponge dried out, not necessarily every day. Cockroaches can go days without water and still be fine. Cattle cannot.
How many cockroaches are needed to equal the protein in a cow, I don’t know. But water-wise, I’m sure the cockroaches win.
Also, wolves won’t eat your cockroach “crop” and you can go on vacation for a week and no supervision of the cockroaches is needed. The down side is many varieties will die if they get cold. They are a “warm weather crop”.


During the Second World War a Canadian Destroyer blew up and sank in the Clyde while taking on ammunition.
Many years later it was becomimg a hazard to navigation as ships got bigger, so it was broken up. Apparently cockroach colonies were found in some air spaces.


Sounds worst than it looks… I’m trying it! Who’s with me?

Tom in Florida

Maybe but don’t bug me about it.

Feed the cockroaches and kale to free range chickens and pigs…just sayin…pick your protein. Bacon and eggs, homemade ice cream, baby back ribs or bugs that taste like peanuts. (…and why not just grow more peanuts? good source of protein)

Terry Gednalske

I wonder how much that cost the Brazilian taxpayers?

Coeur de Lion

Many years ago I caught a large Japanese cockroach eating the dead skin on the sole of my foot. Had to get my back scrubbed at a different place the next time.

Seriously, I would give roach bread a try. It’s just a habit shift, really. Good protein is good protein.


Also in today’s newspaper, here’s a story about a climate saving veggie burger…
Can a veggie burger that bleeds and sizzles like meat help fight climate change?
The Impossible Burger isn’t your run-of-the-mill veggie burger. It’s a burger designed for meat lovers. It bleeds and sizzles like meat – but is made entirely from plants. Now, there’s a better chance you’ll be able to taste it for yourself.

Lucius von Steinkaninchen

As one of the world’s largest beef producers and a country of carnivores (as one may have noticed going to a Brazilian steakhouse) Brazil should be ashamed of financing such nonsense. Also, for a place containing some of the largest rivers in the world and *the* largest reserves of freshwater, the concern about “using infinitely less water” (whatever that means) sounds oddly misplaced.


The roachaphobe haters are out in force today…

Jerry Henson

I do not believe that cockroaches can be eliminated in this way,
so I will stick to my way of being green–eating beef to reduce
methane emissions.

Ed Zuiderwijk

Simples. Feed insects to insectivoreand omnivores. Put said insectivores and omnivores on the menu. Anyone for pangolin, aardvark, warthog, or just pork?

J Mac

A slice of each please, with gravy!

This piece should have had a Trigger Warning for Roach-a-philes — who will be shocked at the sugestion of eating their little friends.
And a separate Trigger Warning for Roach-a-phobes, who are probably much more common, who are shocked at even the thought of eating roaches.
Disclosure: I have been a roach murderer — paid for a family vacation one year by killing roaches for profit.

Bruce Cobb

The ones taste testing the “bread” drew the short straws.


What if this was a double-blind study? Could people tell the difference in the breads? If they didn’t know they were eating cockroaches, maybe they would actually like the bread.


Actually it’s not climate science. This is the cost of corruption in Brazil and the payback for massive corruption in socialist leadership in S. America.


Data (2013 & 2015) on edible insect composition has been compiled by B.A. Rumpold & O.K. Schluter in “Nutritional composition and safety aspects of edible insects” … & also … “Insect-based protein sources and their potential for human consumption: nutritional composition and processing”. Both are available on-line as free full pdf ((if your favorite search engine does not pull these up try using the yandex search engine)).
For anyone interested in rearing assorted insects for purposes like poultry supplemental feed ingredient, value added products, waste processing or even some human use (ex: cricket “flour”) the “Forum” at openbugfarm dot com has a “web” version you can select for with a search function bar (“mobile” version has no search box). I have no commercial interest there, nor is that Forum marketing anything.

Wim Röst

In Thailand insects already are a delicacy. You can buy lots of well prepared insects at the market.


No fried tarantulas? Those freak me out.
There’s already cricket protein powder sold in the USA. (I learned that on Judge Judy.)


unless already digested in my foods gastric system there is no such thing as well prepared insects


So we’re supposed to eat cock roaches to extinction? Lol.


My wife has severe allergies. In December, they did some more testing on her, and she is allergic to cockroaches, even though we don’t have them in this area, AFAIK.


This was the plot of the movie SnowPiercer, with elites living in luxury, while the rest eat bugs. However this was brought on by an attempt to stop global warming.


Sorry, I have a roach allergy. Also, I’m not crawling around in a cave starving to death.

Michael Jankowski

Climate science is full of cockroaches. We should start there.

Rhoda R

This may be the solution to the Venezuelan food crisis though.


Dammit, I did not want to see that first thing in the morning.

Boiled Silk worms are good. Dog is ok.

Patrick MJD

Maybe you haven’t seen how dogs are cooked, if you had you might feel a little different about that.


While briefly in the Highlands New Guinea the locals used to eat cans of dog food, available at the local grocer.
Cans of fish had fish on them, cans of dog food had a dog on them.

Patrick MJD

Cans of dog food in most countries I have lived also has pictures of dogs however, most dog food is vegetable based, except onions, and is safe for human consumption (In regulated countries).

Rich Carman

Before wheat is ground into flour to make bread, samples are taken and analyzed. Virtually every sample has bug parts in them. Not a problem as long as the bug parts are below a certain level. White flour has been bleached with chlorine gas so that the bug parts become white powder that is indistinguishable from the bleached wheat flour.
