Heritage Hogs

Variety isn’t just the spice of life. You could say it is life. And you can’t have variety without lots and lots of genes.

Farmers have spent thousands of years developing livestock that do well in different conditions.

Modern agriculture usually concentrates on just a few breeds that maximize profit. But a lot of people don’t want to see all the valuable genes in older breeds just disappear.

Variety isn’t just the spice of life. You could say it is life. And you can’t have variety without lots and lots of genes.

Farmers have spent thousands of years developing livestock that do well in different conditions.

Modern agriculture usually concentrates on just a few breeds that maximize profit. But a lot of people don’t want to see all the valuable genes in older breeds just disappear.

Lucy Martin visited a farmer who says the future needs to include heirlooms from the past.

(Schaefer entering barn: “Watch your head, it’s a little mucky in here…”)

It’s a bright winter day, inside a classic red barn in Southern Ontario. We’re admiring docile animals whose name says it all: Large Black Pig. They look fine. Even though this pig is listed as critically endangered.

Schaefer: Sometimes you’ll be standing here and you think there are no piglets and suddenly one rises out of the straw!

(Sound of contented grunting)

Barbara Schaefer used live in Toronto. Until a few years ago, her career revolved around managing environmental projects. But when she got laid off, she decided to put theory into practice.

Schaefer: I can’t save the polar bear, but I can save this breed. How many things can you say that about? And that’s why what I’m doing now is 200 times more relevant.

What she’s doing now, is weaving different environmental threads together. Preserving the genetic diversity of rare livestock. Putting marginal land to higher use. Trying to revitalize rural economies. Offering an alternative to factory farming.

Nearly all commercial pork across North America comes from just a few main breeds, usually reared in confinement systems. A lot of science goes into maximizing production. But Schaefer doesn’t think that’s the whole picture.

Schaefer: They’re packed in fairly close, they don’t get the benefit of being outside in the sunlight. They have a artificial concrete floor, which for them, is a horror. Because these guys think with their nose, they want to be turning things up all the time and there’s no opportunity for that.

(Sounds of distant tractor and more pigs grunting)

In the barn yard, I mingle with small herds of thigh-high, curious pigs as they as they mill about, soaking up sun. Some amble over to near-by pastures for naps inside cosy hay huts.

Schaefer’s customers include local restaurants and ‘foodies’, people who like to cook and eat.

Fans admire heritage breeds because these animals were bred to thrive in the specific conditions of small-scale, local agriculture.

Lawrence: They’re rustic, they’re hardy, they’re often good mothers.

Ted Lawrence has spent years on this cause with Rare Breeds Canada. Some really admire the animals. And then there’s the whole ‘insurance’ argument: odd breeds have genes worth keeping. As base stock for even newer breeds, to adapt to changes in climate, or to survive some epidemic.

Lawrence: Food security, that will turn heads more quickly than saying we have to preserve the genetic diversity of minor breeds.

If these animals are special, why slaughter them?

Lawrence: That is actually a slogan that has been used in Great Britain: ‘We must eat them to save them’. It sounds counter-intuitive but what’s the purpose of breeding them if you can’t make any money, if you can’t sell them? Then the genetics will not continue. The breed will go extinct.

(kitchen clatter and music playing at Murray Street Restaurant)

Chef Steve Mitton co-owns a restaurant in Ottawa which features Schaefer’s pork. He’d hate to see old breeds die out.

Mitton: I mean, I get entire animals in and break them down from head to toe, and we use every last bit of it. The yield of the Large Black, in particular, is outstanding.

Mitton says more and more people care about where their food comes from and how animals are treated.

Mitton: I just want to broaden their horizons, open people’s minds a little bit, so they know that this is out there. And it’s just as good as commercial pork.

Most meat eaters have no idea what breed of animal ends up on their plate. But making sure there are lots of breeds around can help keep those plates full, and tasty.

A Rush on Face Masks for Swine Flu

  • Pharmacies have seen a rush on surgical masks, like this one, in response to the swine flu (Photo courtesy of the National Institutes of Health)

Some pharmacies are running out of face masks because people are buying them to try to protect themselves from swine flu. Lester Graham has more on that:

Some pharmacies are running out of face masks because people are buying them to try to protect themselves from swine flu. Lester Graham has more on that:

One infectious disease specialist told us if we get to the point of an epidemic, anything that covers your mouth would probably be helpful.

But, people are not waiting until it’s a full-fledged epidemic before getting face masks.

One pharmacy we visited usually sells three different kinds of masks. It was sold out.

Those who can’t find masks at the local pharmacy are sometimes directed to hardware stores.

Lowe’s Public Relations indicated it has seen an increase in popularity of dust and respirator masks, but the home improvement chain declined to give specific numbers.

Health officials say if you’re going to use a dust mask, buy one rated “N-95.” It filters out 95% of particles.

But, some health officials say, it’s better for those who are sick to wear them than it is for you to wear one for protection from the swine flu.

Swine Flu and Factory Farms: Any Connection?

  • It’s not uncommon for influenza viruses to be exchanged between pigs and humans (Photo by Scott Bauer, courtesy of the USDA)

The current swine flu outbreak was first detected in a region of Mexico with large confined animal feeding operations – factory farms. Many environmentalists wonder if there’s a connection. Lester Graham reports:

A US government brochure indicates it’s not uncommon for influenza viruses to be exchanged between pigs and humans.

Mark Wilson is a professor of epidemeology at the University of Michigan. He says factory farms can make that exchange easier.

“The combination of animals being confined in close quarters as well as the large number of animals is likely to lead to more transmission of infectious agents among them. And as people – workers – are in contact with these animals, the possibility of transmission from those animals to those workers is increased. Absolutely.”

But, Wilson says it’s anyone’s guess whether this strain of swine flu began at a factory farm.

“Completely unknown at this point.”

Health officials from Mexico and the US Centers for Disease Control are investigating the source of the virus.

The “Enviropig” Cuts Pollution

At factory farms, cows and
pigs produce a lot of manure, and
that sometimes causes a lot of
pollution. Julie Grant reports that
one scientist says he’s got a solution:
genetically modify pigs so they produce
less pollution. But to be successful,
people have to be willing to eat
genetically modified meat:

Murray Borrello says pig and cow poop is killing everything
in some of the water he studies. He’s a geologist and has
been researching water pollution with chemists and
biologists at Alma College in Michigan. Borrello says there’s
no fish in parts of the river – because of all the animal feces
running off of nearby farms.

“It’s very obvious. It’s this kind of brown, mucky,
murky looking substance.”

That poop is full of phosphorous, nitrogen, and other things
that cause pollution problems. It creates algae that clogs up
waterways and sucks out all the oxygen.

Borrello says some of the farms house more than
10,000 hogs. Farmers sometimes hold 20 million gallons of
pig manure in lagoons. They liquefy it and spray it on the
fields for fertilizer. But Borrello says it’s too much manure,
so it runs off the land and into the waterways.

In some places, it’s the same water is used for drinking
water. And the same rivers drain into the Great Lakes.

On the northern side of the Lakes, a Canadian scientist says
he’s found a possible solution to this pig pollution problem.

(sound of a pig barn)

It’s called the Enviropig.

Cecil Forsberg has genetically modified pigs so they produce
less pollution in their waste.

I met him at his research barn at the University of Guelph in
Ontario.

There are no windows – just a ventilation system. And,
wow, it’s hard to concentrate – the smell of pig waste is so
strong.

He introduces me to a group of Enviropigs, they’re about a year and
a half old. He says they have no detectable difference from
regular pigs.

“They have four legs, two ears, a snout, and they like to dig
in the shavings.”

But while most pigs poop out a lot of polluting phosphorous,
Forsberg has made the Enviropig into a much better
machine for digesting phosphorous.

He’s no Dr. Frankenstein. But to do it, he did use DNA from
a mouse. He says it’s considered a safe technique, but he
knows it makes people cringe.

“There’s no mouse in these pigs, except for a little fragment
of DNA.”

The mouse DNA allowed Forsberg to add a bacterial gene to
the pigs. It’s that bacteria that triggers the pig’s salivary
glands to start the digestion of phosphorous.

Forsberg says the waste from these pigs does a lot less
damage to the environment than most pigs.

“There’s a reduction in the phosphorous in the manure by up
to 60%. And that’s important because phosphorous is the
component in manure that is the first one that’s problematic.”

And it’s part of what chokes the oxygen out of the waterways –
killing fish and other aquatic species. Forsberg wants to see
Enviropigs bred on the global scale to reduce pollution from
the growing number of large scale hog farms.

Back in Michigan, water specialist Murray Borrello
says reducing phosphorous pollution from giant hog farms
will benefit water quality, but he does not think a genetically
modified pig is the answer.

“The problem is that does not address the issue of all the
other stuff that is very concentrated going into surface water
and ground water.”

Stuff, such as nitrogen and ammonia.

Borrello says a better solution is to reduce the size of hog
farms, so there aren’t so many pigs concentrated in such
small spaces.

But the Enviropig is starting to get some traction.

When Forsberg and his colleagues created the first
generation of Enviropigs, nearly 10 years ago, the question
was: could they do it?

Today, seven generations of pigs later, the question is: will
people eat it?

Until recently, the US government hadn’t allowed the sale
of genetically modified meat. But, the Food and Drug
Administration recently published guidelines for it. And
some industry analysts say you could be eating pork from
animals like the Enviropig as soon as 2011.

Prop 2 to Give Animals More Leg Room

Voters in California are drawing
a line in the sand when it comes to the
factory farming of animals. They overwhelmingly
approved a ballot measure to ensure that
hens, calves and pigs are treated more
humanely. Julie Grant reports:

Right now, in most states, calves raised for veal, pregnant
pigs, and hens that lay eggs are caged so tight they can
barely move.

By 2015, Proposition 2 in California forces farms to make
sure the animals are given enough room to move around.

Michael Markarian is a vice president with the U.S. Humane
Society, which spent millions to get the issue approved.

“You cram these animals into cages barely larger than their
bodies. They’re practically immobilized their entire lives. I
mean, what could be more basic than giving an animal some
freedom of movement?”

Opponents of the issue say this will cost farmers and
consumers. We’ll see more imports from countries that don’t
have these kinds of laws.

Pigs Root Out Evil Bugs

  • Apple grower Jim Koan has discovered that baby pigs are best for taking care of fallen wormy apples in his orchard. He says they have very tender noses. The adult pigs like to root around in the dirt and tend to tear up the orchard. (Photo by Rebecca Williams)

There are a lot of insects that love to eat
apples. A harmful insecticide that kills some of

There are a lot of insects that love to eat
apples. A harmful insecticide that kills some of
those pests is being phased out. So farmers are
looking for other solutions. Rebecca Williams visits
an apple grower who’s counting on pigs to get some
help with his pest problem:

(farm animal sounds – turkeys, etc)

The spring rains have started, and at Jim Koan’s pig pen that means mud.

(sound of shoes squishing in mud and piggy snorts)

Of course, these pigs don’t really seem to mind that.

“These Berkshires, you can see, are really friendly, they’re just coming
right up to you.”

Jim Koan really likes his pigs. That’s because he’s hoping the pigs will
take care of one of his worst pests. It’s a beetle called the plum
curculio. In early spring the beetles lay eggs in the little green apples.
The larvae hatch and eat the apples from the inside out.

Then the tree drops the bad wormy apples on the ground. And the worms just
keep on eating.

For a long time, farmers used an insecticide called azinphos-methyl to kill
the beetles. But the Environmental Protection Agency is phasing it out.
That’s because the EPA says the pesticide is very toxic to some wildlife and
it can make farm workers sick.

Jim Koan hasn’t used the pesticide for 10 years, ever since he became an
organic grower. So for years now he’s been trying to find a perfect
predator to stop the beetle larvae.

The chickens were too lazy. Hawks ate the guinea fowl that he tried.

So, finally, Koan says he had a flashback. His grandpa used to have hogs in
the orchard.

“When I would climb up to go up in the tree in the summertime to get a green
apple to eat all the hogs would come running over there and my granddad
always told me you stay away from those hogs they’ll eat you up! I’d be
really scared and be up there for an hour or two until the hogs left again.”

(laughs)

Koan says he knows now that the hogs were just hoping for a snack. So last
year he decided to buy some hogs and see if they would eat the wormy apples
on the ground. He says baby pigs worked best.

“And they’d just go up one row gleaning it, kinda like little vacuum
cleaners (makes sucking sound) and suck up all the apples!”

Koan says the baby pigs ate 98% of the fallen apples with beetle
larvae in them. But he still needed to know that the beetles were actually
gone, so they wouldn’t come back to attack his apples next year.

That job
was up to researchers at Michigan State University. Koan says they fed a
mix of beetle larvae and apples to pigs on campus.

“Then they put diapers on the hogs – truly, diapers!! It was unbelievable.
They took special superglue and velcroed it on their butt so then when they
defecated they caught all that. Then they took these poor students and made
them go through there and wash all that and look for worms.”

Koan says out of 200 worms that were fed to the pigs, they only found one
worm at the other end. That means, so far it looks like pigs are a
pretty good predator.

But the researchers don’t want to let pigs run wild – just yet. David
Epstein is the lead researcher on the project.

“Jim and I are scheming all the time. I have great expectations that this
could be a good management tool in the future but we have to figure out how
to do it properly.”

Epstein says they need to make sure the pigs don’t cause any contamination
problems. Something like E. coli. He says so far there isn’t any
evidence of that, but it’s the kind of thing you have to be sure about.

If this all goes well, the farmer and the scientist will be writing a book
together. It’ll be sort of a self-help book: getting pigs to take care of
what’s bugging you.

Who Should Watch Big Farms?

Big livestock operations can raise thousands of cows, chickens or pigs
under one roof. It helps keep the price of food lower. But neighbors
complain the government’s not doing a good enough job of monitoring the
pollution these farms produce. Rebecca Williams reports there’s a

Big livestock operations can raise thousands of cows, chickens or pigs
under one roof. It helps keep the price of food lower. But neighbors
complain the government’s not doing a good enough job of monitoring the
pollution these farms produce. Rebecca Williams reports there’s a
debate heating up in several states over who should be regulating these
big farms:


The days of small farms with different kinds of livestock grazing in
the pasture are fading from the landscape.


They’re being replaced by farms that specialize in one kind of animal –
and raise thousands of them. They’re called concentrated animal
feeding operations, or CAFOs.


There are battles in several states right now over who should be keeping an eye
on the CAFOs. Usually, the state departments of environmental
protection have power under the federal Clean Water Act to enforce laws
and issue permits. But in the Midwest, in states such as Ohio and
Michigan, and in the West, in states such as Oregon and Idaho, they either have transferred or are working to transfer oversight power to the state agriculture departments – and get U.S. EPA approval.


Jerry Van Woerkom is a Republican state senator in Michigan. Right
now, the state Department of Environmental Quality – or DEQ – has the
oversight powers. But Senator Van Woerkom is sponsoring a package of
bills that would put most of the state’s big livestock farms under the
Department of Agriculture:


“Those people tend to be supportive and come with the attitude of we’re
going to try to work together to solve this problem. Whereas when they
work with the DEQ the attitude is more like we’re coming with a
hammer and if we find anything you’ve done that’s out of line, we’re
going to wop you with it.”


The CAFOs are in the spotlight because they can produce tens of
thousands of gallons of urine and manure each day. That liquefied
manure is eventually spread onto farm fields.


The Environmental Protection Agency says that waste can wash from
fields into streams and creeks. That can cause fish kills. Animal
waste has also gotten into drinking water and made people sick.


Lynn Henning runs a small farm. She says there are 13 CAFOs within a
10 mile radius of her Michigan farmhouse. She says the manure odors
are overwhelming:


“We can’t hang laundry when the emissions are in the air. We have
severe fly outbreaks. We’ve had family farmers that have been diagnosed with hydrogen
sulfide poisoning from emissions from the CAFOs.”


Henning says the current oversight system is weak. She says the
Department of Environmental Quality doesn’t have enough funding to
monitor the CAFOs. So that job often falls to residents like her. She
says putting the Department of Agriculture in charge of oversight would
make the problems even worse:


“The MDA has no enforcement authority and they promote agriculture in
Michigan. It’s like putting the fox in charge of the chicken coop.
You can’t give authority to punish to an agency that’s promoting.”


But it could become a wider trend if the states that are proposing the
switch now actually make it happen.


Karla Raettig is an attorney with the Environmental Integrity Project.
It’s a group that’s been critical of weakening environmental laws.
She’s been tracking trends in enforcement of livestock farms:


“I think the Farm Bureau and other really large industry advocates are
seeing a chance to get regulation that is perhaps more cooperative,
less regulatory and less on the enforcement side. It isn’t totally
nefarious but I think it could have outcomes that are not anticipated.”


Raettig says you have to wonder what will happen without the threat of
enforcement from an environmental agency.


But Senator Jerry Van Woerkom from Michigan argues that farmers are
more likely to do the right thing if they’re overseen by a friendlier
agency, as he proposes:


“I mean you’re not able to cover up problems that happen, it gets in
the newspaper, people know when problems happen. But I believe that the
agriculture department will work with people, especially if people are
getting a bad reputation. I think they will work with them and if
those people do get out of line, it’s back to the DEQ.”


Environmentalists and small farmers are worried about the idea of
states handing off oversight of CAFOs… from their environmental
watchdog agencies to their agencies in charge of promoting the business
of agriculture.

Point-System in the Works for Large Hog Farms

States might soon be taking a new approach when considering permits for huge livestock farms. The Great Lakes Radio Consortium’s Lester Graham has more:

Transcript

States might soon be taking a new approach when considering permits for huge livestock farms. The Great Lakes Radio Consortium’s Lester Graham reports:


These big livestock growing operations such as hog confinement areas are controversial because they’re smelly and they often have large lagoons of liquid manure. In some cases, that manure leaks into waterways, polluting streams. In Iowa, the Department of Natural Resources is developing an environmental checklist… several dozen things that hog producers can do to score points that make approval of the operation more likely.


They’re things such as keeping the operations far from homes, hospitals, roads and water sources.


Kara Flynn is with the National Pork Producers Council. She says an
Iowa-type plan isn’t necessary for the big pig farms.


“They’re not operating in the 1970’s; they’re operating in 2002. And they’re using technology that allows them to, as best that they can, be environmental or better environmental standards, if you will.”


No other state has gotten this far with such restrictions, but almost every hog-producing state is trying to find a solution to the environmental problems associated with the large confinement farms.

Engineering a Cleaner Pig

Like most farmers, hog farmers have seen a shift from small, family-owned farms, to large-scale hog operations, but more pigs on less land creates some major environmental problems – especially, what to do with all that manure. Bio-tech researchers in Canada believe they have created an animal that will help. The Great Lakes Radio Consortium’s Mark Brush has more:

Tracking Livestock to Limit Diseases

Those worried about food safety say it’s time for a uniform animal identification system – one that could rapidly isolate animals suspected of carrying contagious diseases.

The Great Lakes Radio Consortium’s Mary Jo Wagner has more:

Transcript

Those worried about food safety say it’s time for a uniform animal identification system, one that could rapidly isolate animals suspected of carrying contagious diseases. Wisconsin AG officials have taken the lead on this type of preventive action but will need the help of all the Great Lakes States to make it work. The Great Lakes Radio Consortium’s Mary Jo Wagner has more.


There’s growing consensus among agricultural officials that some type of universal animal identifier is needed to trace animals from birth to the marketplace. Especially in light of recent occurrences of “mad cow” and “foot and mouth” diseases in live animals overseas and the nasty form of e coli in meat products here. Wisconsin secretary of agriculture, Jim Harsdorf says the ID system started in Europe. Now it’s moved to Canada, where it’s mandatory, and Harsdorf says Holland has a central database containing information on all the nation’s animals.


“It’s housed in one location and the producers within 48 hours have an animal ID’d after it’s born and that animal ID stays with it for life.”


Federal officials in the United States have been slow to implement such a system though, so Harsdorf says state officials are working to come up with one. It might be tied to different identification networks that farmers already use to keep production and reproduction records, herd health, vaccinations and the location of cattle that are sold, or it could be a totally new system that keeps some or all of those records on one central computer database managed by state, private or non-profit organizations.


Wisconsin state veterinarian Clarence Siroky says public feedback surprised them. State officials were expecting farmers to want only a voluntary system but what they found at public meetings was that producers want a more comprehensive mandatory system nationwide


“We move cattle all over the United States rapidly…we can have one cow at least touch 27 other states within a week…one pig can touch 19 other states within 24 hours.”


For those reasons, Siroky says, all animals will have to be included, not only cows, but sheep, horses and pigs. In England for example, cows are identified, but sheep are not, and he says sheep were implicated in the rapid spread of foot and mouth disease there.


That concerns Ted Johnson. He’s a Wisconsin dairy farmer who likes the idea of a universal identification system because it would quickly pinpoint the location of animals that might have come in contact with a disease.


“If in the event of an outbreak of some highly contagious disease, it could be stopped very quickly and we wouldn’t have to have wholesale slaughtering of cattle.”


Still Johnson says many farmers are concerned about how much the ID would cost, who would maintain the records, and who would have access to them.


“The worst case scenario would be if that information is released and there is some doubt about the information or if the information is used in an incorrect manner, the perception can be there’s a problem on individual farms.”


State veterinarian Clarence Siroky says that’s why input from farmers, processors, privacy advocates and consumers is important as the technology is developing.


Still to be decided is the type of animal ID that would be used. Siroky says it could be a tag placed on the animal’s ear. However, some animals already have so many different ear tags, he says one ear can look like a Christmas tree. Other possibilities include a computer chip or other type of recyclables monitor placed inside an animal.


Meanwhile, AG secretary Harsdorf says the records included in a computerized type of system could be very beneficial to consumers at the supermarket.


“At some point in time, you’re gonna have the ability to go through a grocery store and see up on a screen when you buy that package where it came from, a picture of the operation — it’s almost mind boggling to see what could happen down the road.”


Still, farmer Ted Johnson worries all the talk right now about the need for animal identification might create a consumer backlash.


“I feel as a producer our food supply is very safe. I don’t want the perception to be that an animal ID program is being instituted because we have a problem.”


But a potential problem without plans to deal with it could create havoc for the agricultural industry, and so far veterinarian Siroky doesn’t know when a system with wide support might be in place. He does say animal health officials are on high alert for the appearance of any contagious diseases. At the same time, he says even if Wisconsin comes up with a proactive plan, unless other states adopt a similar identification method, any tracking system would have limited effectiveness.
