The hamburger you put on the grill this weekend could be from cattle raised on feed that includes chicken feces. Lester Graham reports…a year-old Food and Drug Administration rule says it’s safe.

The rule came about after the mad cow disease outbreak. It made some changes, but still allows putting chicken litter – that’s the straw, feathers, chicken manure and scattered food left after raising chickens in a building– into cattle feed.

David Kirby wrote a book entitled “Animal Factory.” He says the government buckled to the chicken industry because the industry didn’t have a place to go with all the chicken litter.

“There’s too much to spread on local farmland, so they very often put it into cattle feed. It contains urea which cows can convert into protein.”

Chickens are messy. They scatter their feed and it gets into the chicken litter that’s put in some cattle feed. Some chicken feed contains beef by-products. Kirby says cattle eating cattle by-product could risk another outbreak of mad cow disease. The FDA says there’s no measurable risk.

Farmers are finding they can
make more money selling crops
for energy than for food. A third
of all corn grown in the US gets
turned into ethanol. It’s tough
to balance the need for energy
and food when millions around
the world die from starvation each
year. Still, farmers are reconsidering
their roles – including in Germany.
In the second part of our three-part
series on biofuels in Europe, Sadie
Babits meets with one German
farmer who wants to make the switch
and become an energy farmer:

Erhard Thale jokes a lot about being an organic farmer. It’s about all he can do.

“He has like his corn harvest from two years ago is still lying down on his farm so it’s not sold on the market.”

It’s hard to imagine. We’re outside Ludwigsfelde not too far from Berlin. Thale’s land looks green and healthy – not bad for late fall. But looks can be deceiving. Thale says he’s lost money for the past three years. He blames his land and a volatile world market.

“Then My wife comes and asks, ‘where do we go from here? Piggybank is empty. Money gone.’”

Thale says he can make more money selling his organic corn and rye for energy instead of food. He’s not joking around. There’s a growing movement in Germany to get farmers like Thale to set some of their land aside to grow grains just for energy. There are now areas throughout the country developing so called “bio-energy regions.” The idea is that a community like Ludwigsfelde would produce its energy locally.

Farmers like Thale would sell their grains and manure to a regional bio-energy power plant. Those materials would get turned into green energy. The 20,000 residents who live here wouldn’t have to rely on fossil fuels and they’d cut down on greenhouse gas emissions. Sounds promising. But Thale says he’d build his own plant if he had three million dollars. Then he could keep all the profits from selling energy.

“He needs an uncle in the U.S. with two million euros.” (laughter)

Other farmers, though, are cashing in, finding money in, well, poop.

(sound of milking machine)

A cow chews her cud as an automatic machine does the milking. This milking parlor is part of an agricultural training center here in west central Germany. This is the greenest farm I’ve been on. There’s a bio-energy power plant. Wind turbines and solar arrays.

Klaus Wagner runs the center. He says this cow’s manure is more valuable than the milk.

“That can’t be.”

Wagner sees a growing rivalry between dairy farmers who want to sell milk and those who want to sell manure for biogas.

“I guess that the milk and energy production on the other side belongs together. And those farmers who built 3-4 years ago biogas plant they earn real money now. The biogas plant substitutes the milking production.”

It really comes down to a question of sustainability. How much land here in Germany and, for that matter, the U.S. should be set aside for making energy? It’s not an easy answer. In the long run, if farmers grow grains for energy instead of food, that will impact the food supply and eventually what we pay at the grocery store.

The US Forest Service has
announced it will not increase
fees for ranchers who let their
animals graze on public lands.
Rebecca Williams reports that
makes some environmentalists mad:

Ranchers have to pay to let their cows, sheep and goats eat plants on public land. This year, that monthly fee is staying put at $1.35 for each so-called “animal unit.” For example, that’s a cow and her calf, or five sheep.

Taylor McKinnon is with the Center for Biological Diversity. He says livestock grazing is one of the reasons species like the desert tortoise and Mexican gray wolf are in trouble. And he says taxpayers are subsidizing livestock grazing, and then paying to fix the damage it creates.

“We have the U.S. Fish and Wildlife Service whose recovery programs are spending tremendous amounts of money to recover species who have been imperiled by livestock grazing.”

McKinnon says raising grazing fees would increase costs for ranchers.

No one at the National Cattlemen’s Beef Association was available for comment.

Money for Methane

The US Department of Agriculture
is planning to give dairy farmers
more money to cut some of their
greenhouse gas emissions. Rebecca
Williams has more:

Cows are gassy. They burp methane gas and their manure also emits methane. Methane is 21 times more potent than carbon dioxide.

In Copenhagen, Ag Secretary Tom Vilsack promised to cut greenhouse gas emissions on farms. He said the government will be giving farmers more money for methane digesters. They’re machines that capture methane from manure.

Katie Feeney is with the environmental group Clean Air Council.

“If you can make it easy for them and cost effective for them to be sustainable, to reduce their emissions, then I foresee a lot more people participating in programs such as that.”

But some environmentalists say voluntary programs are not enough. They say big dairy farms should be regulated more.

Starting in the New Year, all kinds of businesses will have to report their greenhouse gas emissions. But there’s a big exception: large concentrated animal farms don’t have to.

Milk and Manure in the Dairy State

(sound of a farm)

Tom Crave and his brothers run this dairy in central Wisconsin. Crave says, when they first started out, he and his brothers were single, they had 80 cows and a used car.

Now, they have around a 1,000 cows and families to look after. He says they had to get big to survive.

“It takes a lot of money to live. That’s what’s… that’s what’s driven this here. It’s just basic economics.”

It’s a theme farmers all over the country have been hearing for decades. Get big or get out. You can’t make money unless you grow.

The Crave Brothers milk their 1,000 cows three times a day. They use automated milking machines. And they turn that milk into cheese that they make across the street in their cheese factory.

But milk is not the only thing cows produce. These farms deal with millions of gallons of liquid manure.

Most farms store the manure in lagoons – basically huge pits of waste contained by earthen berms. Then, when these lagoons fill up, they spray or inject the liquid manure onto the ground as fertilizer for crops. It’s also the main way they have to get rid of all that waste.

Sometimes these big dairy farms have problems. Liquid manure runs off the crop land, contaminating rivers and lakes. And, in some cases, the earthen berms holding back the manure has leaked or given way, releasing a wave of manure, causing huge fish kills or polluting well water.

But regulators here say the Crave Brothers have been doing a good job taking care of their manure. As have most of the other big dairy farms in Wisconsin. That’s in part because these farms actively regulated in the state.

Gordon Stevenson is the Chief Runoff Manager for the Wisconsin Department of Natural Resources.

“It is not coming from these largest farms for the most part. The manure management on our 30,000 other smaller farms can be a good bit worse, and those people are not regulated.”

Dairy farms that have fewer than 700 milking cows usually are not regulated under the Clean Water Act until there’s a major problem. And some farms stay under 700 cows to avoid regulations.

“When we encounter environmental problems associated with one of these smaller farms, they can be offered cost share assistance. They’re largely voluntary programs.”

If Stevenson finds a smaller farm that’s polluting, he can offer them some state money to fix the problem. But, beyond that, he says there’s not much his office can do. As a result, some smaller farms pollute.

Jamie Saul is with Midwest Environmental Advocates. His group has represented people who were sickened from well water contaminated by manure. Saul says, there have been some problems with bigger farms in the state, but he admits the bigger challenge is how to control pollution coming from smaller, unregulated farms.

He says just offering them money to clean up is not good enough.

“We are the habit now of paying, and I think it’s pretty unique to the agricultural industry, that we pay them to reduce their pollution. Most other industries we don’t do that. We expect whatever industry it is to come into compliance with whatever standards are needed to protect the environment and public health.”

Saul says all states needs better policies to keep small farms from polluting. He says the regulations have to have that magic mix of stopping water pollution without putting too much burden on small farmers.


While Wisconsin regulators seem to be keeping an eye on their bigger farms, environmental activists say that’s not the case in other states. They say Clean Water Act rules are often not enforced against livestock farms – big or small – and that puts the environment and people’s health at risk.

Growing Food With Fumes

  • John Vrieze has a machine called a digester on his dairy farm that's used to turn manure into energy (Photo by Todd Melby)

Big dairy farms produce more than just milk. They also generate manure. Lots and lots
of it. That can be a problem for farmers and the environment. Todd Melby reports on a
technology that reduces manure and generates electricity:

Big dairy farms produce more than just milk. They also generate manure. Lots and lots
of it. That can be a problem for farmers and the environment. Todd Melby reports on a
technology that reduces manure and generates electricity:

(sound of suckling cows)

I’m on a dairy farm with John Vrieze and his daughter Brittany.

Oh, and some cows too.

Vrieze is a frugal man. A couple of winters ago, he had a contest with his son to see who
could use the least electricity. Vrieze was willing to go to extreme measures.

His daughter Brittany tells the story this way:

Brittany Vrieze: “He’d shut his fridge off in the winter time. Just use the outdoors for his
fridge. He was definitely trying to keep the kilowatts down.”

Todd Melby: “So what did he do? He just kept his milk in the porch?”

Brittany Vrieze: “Yup.”

Todd Melby: “And kept his frozen stuff outside?”

Brittany Vrieze: “Yup. Yup.”

Today, Vrieze isn’t just trying to save energy. He’s trying to create it.

(sound of cow moos)

From cow dung.

He’s got 1,600 head of cattle at his place here in western Wisconsin. Those cows produce
milk that gets made into cheese. But they also produce about 50,000 gallons of manure
— every day.

Farmers are required to store that manure in a big pool-like structure called a lagoon.
John Vrieze covers his up with a giant tarp.

“It would blow up from the biogas. It would look like a great big balloon or like the
Metrodome, for folks in the Cities. It’s from the nature decomposition of the manure. It
creates biogas. We would have to take that gas out from underneath the cover and flare it
off, which got us to thinking that there has to be a better way to use that energy than just
to flare it off.”

So Vrieze bought a $1 million machine called a digester. And he had help from the
federal government. They paid for a quarter of it. The government is interested in these
things because they can turn manure into energy.

And it turns out — the reason it’s called a digester — is a farm thing.

“A cow has four stomachs. We call the digester really the fifth stomach. All the stuff that
comes out of the back of the cow we then put in that digester.”

So this “fifth stomach” produces energy. However, it’s not ready-to-use energy. To sell it
as natural gas, it has to be about 95% methane. The gas from the digester is only about
60% methane.

(sound of pipeline burn off)

Another option is to convert it to electricity. But in the U.S., electricity is cheap.

Todd Melby: “You tried to sell it to the electric company, but they didn’t want it.”

Brittany Vrieze: “They’re not offering us enough money. So …”

After all this investment by Vrieze and the federal government, some of the gas he
collects is just being burned off into the air.

But maybe not for long.

Vrieze wants to build a greenhouse right on his Wisconsin farm so he can grow
vegetables and herbs in the winter. He says he’ll power it with energy from the digester.

“So, instead of your produce coming from 2,000 miles away – from the central valley of
California – wouldn’t it be neat if it came from 45 miles away?”

Vrieze is planning to use the water from the cow manure for his vegetables and herbs in
his greenhouse. And he’s got a machine similar to ones used at wastewater treatment
plants to clean the manure water.

But even with the digester, there’s still leftover manure he has to deal with. But Vrieze
says the digester makes it more manageable.

(blowing sound)

Some of the dry manure is blown into a pile where it’s gathered up and used as bedding
for the cows. In the summer, it’s also used for another purpose.

“It’s just a clean version of manure. It stinks a little bit. Most of the stink has been taken
out of it. And we mix this with potting soil and it works great for the plants. So …”

That manure/potting soil mix is sold to gardeners in the city. It’s another way for Vrieze
to be frugal and environmental at the same time.

Dollars and Streams

When you hear about dead zones in the Gulf of Mexico and the Great Lakes, they’re largely caused by pollution draining from the farm belt. It can take a long time and a lot of money to reduce pollution at factories. So they’re starting to pay farmers to cut pollution instead. Julie Grant explains:

When you hear about dead zones in the Gulf of Mexico and the Great Lakes, they’re largely caused by pollution draining from the farm belt. It can take a long time and a lot of money to reduce pollution at factories. So they’re starting to pay farmers to cut pollution instead. Julie Grant explains:

When you eat cheese, you might not realize that something so delicious creates a lot of waste. And that waste – that pollution – ends up going into the drain. It eventually ends up in rivers and lakes.

(sound of a factory)

We’re at a cheese factory in Holmes County, Ohio where they make nearly 60,000 pounds of cheese a day.

The big stainless steel vats look immaculate. But our shoes are wet.

Bob Ramseyer is CEO of the Alpine Cheese Company.

He says the floors are covered with water because the equipment is constantly being washed.

“We have a pre-rinse – that goes to drain. We have a final rinse, and that goes to drain. And we have all the floors that are flushed down and so forth, so that all ends up as part of the wastewater.”

The cheese factory’s wastewater includes not only those caustic chemical cleaners, but wasted milk by-products. One milk nutrient is the chemical, phosphorous.

About a decade ago, the Environmental Protection Agency told Ramseyer that the cheese company had to reduce the phosphorous it was releasing into the nearby river. Ramseyer was concerned.

“The equipment alone was going to cost a half million dollars. We projected it was going to cost between a half million dollars and a million dollars a year in operating costs. So we were looking for any way we could to reduce that cost. That’s where we got into the nutrient trading program.”

Alpine Cheese was among the first to negotiate what’s called a nutrient – or water quality – trading program. Instead of reducing the phosphorous coming from his factory, he pays farmers to reduce manure – another source of phosphorous – from washing from feedlots into the river.

(sound of cows)

Mervin Hershberger is an Amish dairy farmer with 125 acres and 54 milking cows.

(sound of a stream)

His farm looks like a postcard – beautiful hilly green pasture.

But a lot of the manure was washing off his farm into the streams. Herberberger says the cows were grazing right around the water.

“With the cows being in the creek we could see dirty water. The rocks were covered with dirt from cow’s waste. You walk through the stream, you’d kick up dirt and waste from the cows.”

Hershberger didn’t like it, but he didn’t have money to change it.

So when the County Soil and Water Conservation District held a neighborhood meeting to explain that Alpine Cheese was going to pay to reduce pollution from nearby farms, Hershberger saw a way to afford to clean up his farm.

He did about a dozen projects to reduce manure run-off into the water, like building a fence to keep the cows out of the stream.

And the little creek is bouncing back:

“As of now, it’s just totally clean, what you see. For the minnows and all the critters that are in the creek.”

Hershberger gets paid for the amount of phosphorous he keeps out of the water.

About 25 other farms in Holmes County are doing similar projects to reduce water pollution. And Alpine Cheese foots the bill. In exchange, the company doesn’t have to clean up wastewater coming from the cheese factory.

It’s a lot like a cap and trade program on water pollution.

There are a growing number of small programs like this around the country. But some people are trying to create water trading projects on a much larger scale.

That would mean a factory in one state might be able to pay farmer in another state. Eventually, all of the thousands of factories in just one river basin could pay farmers enough to reduce dead zones like the one in the Gulf of Mexico and in some of the Great Lakes.

Curbing Cow Burps

Cows burp methane gas. It’s a potent greenhouse gas. The Environmental Protection Agency says cow burps alone make up 20% of the methane emissions in the US. Rebecca Williams reports some people worry the government might step in:

The farm lobby’s worried Congress will try to regulate gassy cows.

But if you thumb through the giant climate change bill before Congress, you’ll find Section 811. That section says the government can’t regulate cow burps.

In the meantime, some farmers are trying to make their cows less gassy.

The company Stonyfield Farm is getting its dairy farmers to change their cows’ diets.

Nancy Hirschberg is with the company. She says the new diet has cut cow burps by 12%.

“It’s very much like people. When you are feeling good, you’re not having a lot of gas – you’re more efficient, more of your energy is available for living life. The same with the cows, you want as much energy as possible to go into producing milk, not into burps which are in fact, waste.”

She says the cows also have sweeter breath.

Organic Meat Hard to Find

Organic farmers would love to have you dig into more of their pork, chicken and beef.

Organic farmers would love to have you dig into more of their pork, chicken and beef.

It’s not just because they’re proud about how they raise their animals – it’s because certified organic meat fetches high prices.

But organic meat is harder to find than you’d expect, and it’s partly because there are few organically-certified slaughterhouses.

Shawn Allee found a farming community that came up with a solution:

Dennis and Emily Wettstein turned their Illinois farm organic a while ago, mostly because conventional farming wasn’t practical for them.

“All the money seemed to go to pay for the fertilizers and the chemicals. And then I was more or less allergic to the chemicals. And so we were interested in getting away from that, especially if we were going to raise a family out here.”

The Wettsteins didn’t just raise grain organically – they kept chemicals and hormones out of their cattle.

“We started raising meat for ourselves and our families. Then, pretty soon, just word of mouth, friends and neighbors wanted meat.”

And, they found people who’d pay top dollar for their meat.

“We sell at the Oak Park farmers market.”

That’s just west of Chicago.

“Right. The Oak Park market managers, they are working on all the farmers to go towards organic.”

And that worked for the Wettsteins – they had USDA certified organic chicken.

“There’s one other meat vendor there – it’s not organic. So, we have no competition. We feel that, with that label on there, we can set our price to where we can make a profit.”

But Emily Wettstein says that term – organic – gave them trouble when it came to beef and other meat.

“We were getting a little bit pressured from other people, ‘Well, you can’t call your item organic. You don’t have a processing facility with the term of certified organic.'”

Here was the problem: For meat to get labeled USDA certified organic, it’s gotta be certified from the farm to the slaughterhouse.

The Wettsteins had someone to process organic chicken, but they were out of luck with pigs and cows.

There was no certified slaughterhouse for beef or pork in Illinois.

So, the Wettsteins and some relatives prodded meat lockers to get certified.
There was one taker.

“I’m inside a meat locker that’s about a fifteen minute drive from the Wettstein farm. It’s owned by Scott Bittner, and I’m here to understand what organic certification means for his business. How do I put this, there’s a headless, hoofless, skinless cow hanging from your ceiling. Where are we exactly?”

We’re on the kill floor. We had seventeen, eighteen cattle today. Seven of those were organic.

So, walk me through how you have to treat that organic cow differently.

It’s the first thing we did this morning – that’s one thing. Other than that, it’s segregating it in the cooler from the non-organic product and then processing it at a later time, which, again, you have to do first thing in the morning.

So, the basic idea is segregation?

Yeah, it is. The whole way through. Exactly.

Bittner’s simplifying things, but not much.

He has to clean or swap equipment between batches of organic and conventional meat.

There are rules on the kinds of chemicals he can use. And he hires a certification company to monitor his paper work.

Bittner says overall, it’s easy, and he’s surprised more slaughterhouses haven’t done it.

“Here we’re doing all our fabricating – grinding sausage, ground beef. Cutting some chops, ribs.”

“How does it feel to be the only guy who can process an organic side of beef?”

“I want to keep it quiet – I don’t want too many people to get started doing what I’m doing because it’s nice. I get two or three customers every year that I didn’t have before. When you go to bed at night and think about this economy being the way it is, every little bit helps.”

Bittner says farmers drive animals up to four hours to slaughter their animals here.

He says he’s proud of his work but can’t take too much credit; he knows he’s got a local organic slaughtering monopoly going.

That might change some day, but for now it’s reason enough to keep his knives sharp.

factory farms to make energy from their waste.
Julie Grant reports:

Several states around the nation are offering tax breaks to
encourage factory farms to capture the methane from their
cow manure – and to convert it into usable electricity.
Methane is one of the worst greenhouse gases contributing
to global warming.

You might think environmental groups would support the
idea. But Ed Hopkins of the Sierra Club says taxpayers
should not subsidize manure-to-energy projects.

“We see factory farms as a business. And like any business,
they should pay the costs for their pollution control
equipment – not the public.”

Hopkins says taxpayer money for manure to energy projects
will only encourage more factory farming and the other
pollution problems associated with those big operations.
