If you had a bowl of cereal or maybe a muffin this morning, you ate flour from an annual crop. They grow one season, they die, then get re-planted again the next year. Sounds as natural as could be, but repetitive planting can wear out farmland. It can cause soil erosion and cause more water pollution. Now, some scientists are trying to coax grain crops into growing for years at a time. Shawn Allee visited researchers who are testing perennial wheat in the heart of cereal country:

I’ve headed to a test farm run by Michigan State University. It’s not that
far from Battle Creek,
Michigan where cereal companies like Kelloggs got started.

Dr. Sieg Snapp shows me grain that might make into our cereal bowls
someday.

Allee: “What are we looking at on this side?”

Snapp: “We have 6 varieties of perennial wheat.”

Right now, they kinda look like spindly blades of grass. But in some ways,
this is miraculous; regular
wheat dies after harvest. These have been harvested, and now they’re
popping back up.

“We’ll harvest these this summer, and then in the fall, they’ll re-grow.
They build a deep root
system, and they’re able to come back. So, at first, they start off very
similar, but they keep
growing longer, and they re-grow after harvest. That’s the real
difference.”

Actually, that’s just the start of the difference between annual grains
like wheat and perennial
varieties.

Dr. Snapp says when farmers plant most annual grain crops, soil gets torn
up again and again from
planting and replanting. Rain can wash away exposed top-soil.

Perennial crops get planted once every few years, so they might hold soil
and they might need less
fertilizer that runs off into streams and rivers.

Snapp: “So, the roots of traditional crops including annual wheat are
usually 1-2 feet. These
root systems might be down 6 feet. They can use fertilizers more
efficiently, so they can pick
it up from deep and then move it up where we want it, into the grain.”

Allee: “And if the roots are deep enough, you might need less herbicide
to kill weeds, right?
If that perennial wheat comes up strong enough, it’s already out-competing
the weeds that
are next to it?”

Snapp: “Right, and each year it should do it better for a couple years at
least, we don’t know
how long.”

Dr. Snapp and her colleagues use the word “maybe” a lot when they talk
about perennial grains. It’s
mostly because testing these crops is slow work. That’s one reason they’re
letting some farmers run
their own small tests.

She introduces me to one farmer.

“Hi John! Come on over!”

Part-time farmer and teacher John Edgerton says he checked his test batches
recently.

“I didn’t know what to expect and I went out there and low and behold,
it’s greening up
beautifully. In fact, now, it may be a little too thick. We’ll see.”

Edgerton wants to know whether sheep can get cheap feed from leftover wheat
grass, or whether
farmers could save on tractor fuel.

“One farmer said to me, you know, if I could get three or four years of a
decent crop of
perennial wheat without having to plow, there’d be enormous savings.”

Pretty soon, another perennial wheat researcher joins us in the test field.
He’s Brook Wilke.

He tells me, all this work on perennial wheat and other grains will work
best if the final product, the
grain, tastes like what we’re used to.

Allee: “I hear you baked some chocolate chip cookies with perennial
wheat.”

Wilke: “Yeah. A big component of this work is, “’will people eat the
perennial wheat?’”

Dr. Snapp tasted Wilke’s cookies. She says the wheat tasted kinda nutty,
but good.

Dr. Snapp says maybe one day, she and other researchers will prove
perennial grain plants can thrive.
After that, maybe bread or cereal companies, like Kellogs, will run
taste-tests of their own.

Government Fails at Food Safety

Government agencies admit they need to do a better job at keeping food safe. Kyle Norris has more:

When you discover people are getting sick from a food bourne illness like salmonella, you want to stop others from getting sick from it as fast as possible.

A report by the Centers for Disease Control and Prevention, the US Food & Drug Administration, and the Department of Agriculture finds the government is not getting any faster.

The report found the number of reported salmonella cases each year is about 15 people in 100,000. That has not gone down since 1996.

Lola Russell is a spokeswoman for the CDC.

“We are planning to increase the capacity of state health departments so that outbreaks can be better detected and investigated.”

Russell says the CDC will work to get more “boots on the ground” to detect an outbreak. The report also indicated the FDA is looking at the best options to prevent food borne illnesses in the first place.

New Rules for Cement Pollution

  • Cement kilns produce mercury, which gets into the fish we eat making it unsafe (Photo courtesy of the US Fish and Wildlife Service)

After years of urging, the US Environmental Protection Agency is proposing regulations to cut down on pollution from cement kilns. Lester Graham reports:

Transcript

After years of urging the US Environmental Protection Agency is proposing regulations to cut down on pollution from cement kilns. Lester Graham reports:

Cement – the stuff used to make concrete – is made by baking limestone and other ingredients at really high temperatures in huge coal-burning ovens.

Burning the coal and baking the stone both release mercury. The mercury gets into the food chain and contaminates fish.

Mercury is a neuro-toxin, so eating contaminated fish can cause health problems, including IQ loss.

For 20 years Congress and the courts have been telling the EPA to do something about mercury pollution from cement kilns.

Jim Pew is a staff attorney with Earth Justice, an environmental group. It’s sued the EPA over the issue.

“The government response until now has not been to try to get mercury under control, since everybody agrees it’s a problem. The response has been to tell people ‘mercury is out there, so don’t eat the fish.’”

Under the EPA proposal, cement kilns would have to clean up the mercury and other pollution emitted from their smokestacks.

Zapping Germs Off Your Food

Researchers are working
overtime to find ways to kill dangerous bacteria in food such as Salmonella and E. coli. Rebecca Williams reports one researcher has found a new way to kill bacteria:

Food processors expose produce like lettuce to ozone for a few seconds or minutes to kill bacteria.

Kevin Keener has been working on a device that turns the air inside food packaging into ozone.

Keener is a food process engineer at Purdue University.

He attaches the device to the outside of food packages – like a bag of lettuce – and applies electrodes that send high voltage through the bag.

“Visually it’s very Frankenstein-ish. It’s a safe process, there is a high voltage, but it’s similar to a spark you’d get with an electric fence.”

Keener says the ozone spends more time with the food so it kills more bacteria.

There’s a problem though – in some of their tests the device turned green spinach white.

So there are a few kinks to work out. But food companies are interested and we might see this commercialized in a year or two.

City Turns Mucky Grease Into Fuel

One city’s new program is taking the mucky sink-clogging grease from restaurants and converting it into fuel for its fleet of vehicles. As David Gorn reports, it’s the first effort of its kind in the nation:

It’s 6 in the morning, and a San Francisco sewage treatment plant is already in full gear.

(sound of a truck motor)

Workers are unloading a tankful of used cooking oil from local restaurants.

(sound of a man shouting)

But soon they’ll also be picking up something a little nastier from restaurants.

“Brown grease is culled out, pumped out by grease haulers and taken out of the city, often to landfills.”

That’s Karri Ving, biofuels coordinator for the San Francisco Public Utilities Commission. She says, instead of carting that grease off to a garbage dump, it will now be converted into biofuel.

“That material, that food material, is what we’re going to condense into a putty that gets converted into road-worthy biodiesel.”

Ving says San Francisco expects to process about 10,000 gallons of the
stuff every day.

Organic Meat Hard to Find

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.

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.

Serving It Up Green

Some big corporations and some small businesses are taking a serious look at their impact on the environment. Some are using a science-based framework called the Natural Step to try to operate more sustainably. Stephanie Hemphill visited one, and has this report:

The Duluth Grill is a family restaurant. Tom Hanson is the owner here. He says things started changing for the restaurant when he decided he should be offering healthier foods. He says too many of us are gaining too much weight. So he changed the menu, and now he says people can still go out and have a good time without it all going to their waist.

“Whether it’s French fries or fruit or healthy home-made soups, people can be socially engaged eating out but you’re not necessarily sacrificing your eating habits or eating styles.”

His menu offers healthy ethnic meals, gluten-free foods, and teas that claim health benefits.

Once Hanson started thinking about the health and well-being of his customers, he started thinking about the other impacts of his business. He joined a group of about a dozen businesses recruited by a local non-profit to try out the Natural Step approach to sustainability. The Natural Step was developed in Sweden, but it’s being used all over the world.

Restaurant staffers attended training sessions on how ecosystems work, and on what it means to be sustainable.

Manager Jeff Petcoff shows off the new LED lights in the restaurant.


“They produce 12 watts of energy versus 320 watts from the regular light bulbs that we were using prior to this. It’s a little more intimate with dining at night, but we’ve had a positive reaction to that as well.”

The Natural Step program encourages reducing the use of fossil fuels and other resources that have to be mined from the earth. And it calls for not throwing as much garbage into the earth.


In the kitchen, workers separate the trash. There’s a bin for recyclables, one for trash, and one for food scraps. Petcoff says the food waste goes for compost.

“We’ve just made it very easy for our staff to be able to compost and recycle with the bins all over the restaurant.”

The Duluth Grill has reduced its weekly trash pickup, and saved a bunch of money in the process. Owner Tom Hanson says saving money is nice, but part of the Natural Step program calls for not degrading the earth, like by building landfills.

“We don’t live next door to landfill but somebody does, and once you become aware of it, I think, it becomes more compelling to do it.”

And the restaurant encourages its customers to get involved in helping each other. Next to the front door there’s a bin where people can dump their old magazines. A local youth center is recycling them to raise money.

And there’s a bookshelf where people can leave children’s books; it’s part of a community-wide literacy campaign.

One Natural Step principle is about people: a sustainable business operator makes sure the people who work there, and even the suppliers and customers, anyone who has contact with the business, can meet their needs without a big struggle.

Tom Hanson dreams of offering health coverage to all his staff — and maybe someday even child care.

“You could easily consider day care for your staff as being an expense that no small operator could afford. But when you make change little by little, that step could very well enter into our values, and once it becomes one of our values it becomes affordable.”

Many businesses are making these kinds of changes and you might not even be aware of it. But Tom Hanson would say if you’re not sure, ask. You might prompt someone else to do better.

Stores Required to Label Some Foods

Starting this week, supermarkets are officially required to tell you where some of your meat and produce comes from. But as Rebecca Williams reports it can get confusing at the store:

This rule requires stores to tell you what country some of your food comes from.

The rule covers things like beef and pork, chicken, and vegetables.

Supermarkets have already been adding these labels over the past few months.

Deborah White is with the Food Marketing Institute. The group represents supermarkets. She says they don’t like being forced to label specific products – and the law is quirky.

“The law applies, for example, to chicken but not turkey. It applies to peanuts and pecans but not almonds and walnuts and those were decisions that Congress made.”

And there are other quirks. Frozen peas have to be labeled and so do frozen carrots. But a bag of peas and carrots mixed together doesn’t have to be labeled.

The new agriculture secretary, Tom Vilsack, says he wants to fix these quirks. He’s asking the food industry to voluntarily add more information to labels than the rule now requires.

Kicking a Chemical Out of Cans

  • Tomatoes are posing a problem for a BPA-free lining - they are so acidic they can eat through it (Photo by Scott Bauer, courtesy of the USDA)

More than a hundred studies have linked a chemical in plastic to health problems. Things like breast cancer, prostate cancer, diabetes, and early puberty. This chemical, bisphenol-A or BPA, is used to coat the inside of baby formula cans and almost all food and soda cans. Rebecca Williams visits one company that’s found a safer can:

More than a hundred studies have linked a chemical in plastic to health problems. Things like breast cancer, prostate cancer, diabetes, and early puberty. This chemical, bisphenol-A or BPA, is used to coat the inside of baby formula cans and almost all food and soda cans. Rebecca Williams visits one company that’s found a safer can:

(sound of forklift backing up, pumpkin seeds pouring out of roaster)

It’s pumpkin seed roasting day at Eden Foods. It’s a natural foods company based in Michigan. It sells things like rice, canned beans, and all kinds of packaged fruits and sauces.

Michael Potter is the company’s president. More than a decade ago, he came across some news reports out of Europe.

“And I learned all the can linings in the USA were lined with this lining that leaches BPA into foods from the can.”

That got him thinking, and researching. Then he started badgering his can manufacturers.

“We virtually begged them to provide us an alternative. We persisted in hounding them and eventually the Ball Corporation said they’d make a can with an old lining they used to make.”

The lining’s made from a plant resin instead of the epoxy resin with BPA. The thing was, it would cost Eden Foods 14 percent more – that’s about 2 cents a can.

But Michael Potter says he had to make the switch.

“We’re selling this not only to people that we don’t know, in the market, we’re feeding it to our children, our grandchildren and ourselves – we didn’t want to eat bisphenol A.”

But there was one problem. He couldn’t make the switch for canned tomatoes.

Tomatoes are acidic, and they can eat through the plant resin can lining. That could lead to bacteria or rust getting into the food.

“There is no alternative for high acid foods other than bisphenol-A lining at this point. We are urging, nudging, demanding a bisphenol-A free alternative. And we’re optimistic we’ll end up with one.”

But the metal can industry says those alternatives just don’t exist right now.

John Rost is with the North American Metal Packaging Alliance. He says the industry is trying to find new materials. But he says shoppers shouldn’t worry about eating canned food.

“The levels of BPA that are coming from epoxy can linings are exceedingly low. We’re talking low parts per billion. That level has been deemed safe by the European Food Safety Authority, Health Canada and the US FDA.”

That’s true, but Health Canada has declared BPA toxic. It’s making moves to limit its use.

A number of independent scientists debate that there’s any safe level of BPA.

Maricel Maffini studies BPA at Tufts University School of Medicine. She says they’ve seen harmful effects on lab animals at the same very low levels of BPA that are leaching into our food from cans.

She says that’s because BPA acts like the hormone estrogen.

“You just need a tiny little signal to trigger an effect. So I think it’s unfair to say there is a safe dose because as scientists we cannot say that yet. We have not found a dose that is low enough where we don’t see effects.”

She says babies and kids are the most at risk. She says BPA has caused lasting damage in lab animals when the animals were exposed to the chemical both before and after birth.

“I think we should be concerned, I think we should limit our consumption of canned foods especially if you are pregnant or if you have babies.”

It’s possible that US can makers will be forced to stop using BPA. Leaders in Congress have introduced bills that could soon ban BPA in all food and beverage containers.

Green ‘Stop-N-Shops’

Not that long ago, if you wanted to buy eco-friendly at the grocery store, your options might have been limited to the granola and beans in the bulk bins. Then stores started carrying organic produce. Later vegetarian fast food appeared. Devin Browne reports now eco-friendly is hitting convenience stores:

They’re called ecovenience stores and they’re showing up all over the country. The point is that they sell convenience store food, only greener.

(sound of a store)

“This is our organic hot pretzel, we have organic hot pretzels. It’s organic flour.”

That’s Melissa Rosen; she co-owns a new ecovenience store in Los Angeles, called Locali. Which is actually spelled L-O-C-A-L-I.

And they’ve got hot pretzels, but organic. Hot dogs, but grass-fed. The store even looks like a convenience store: It’s in a strip mall, it’s near a freeway. They’ve got cold drinks in the fridge and impulse buys like candy near the cash register. The customers are in a hurry, but a happy hurry. They rave about the chips

“It is a flavor explosion in your mouth, it is beyond savory.”

and the slushies.

“Slushies! There you go, the slushies are amazing.”

But then you get closer and you see that the cold drinks are not soda or beer: They’re Kombucha, the fermented tea. The candy is vegan gummy bears and organic lollipops. And the slushie, their signature item, is sweetened with agave.

There are a few 7-11 staples that are missing from the shelves, like cigarettes and lotto tickets. The owners say there are no green versions of those.

Some of Locali’s products are really pragmatic and not that exciting like energy efficient light bulbs and ecological laundry drops. Others are kind of sensational, silly, really.

“For example the vegan condoms. What is that, what is Glyde? I didn’t know my condoms weren’t vegan.”

So, vegan condoms, vegan caviar. Snow cones sweetened with brown rice syrup. They have this really big variety of products that have never been greened before.

And so the question becomes: will new green products like these, however silly, really mean new green consumers? Matt Kahn is an Environmental Economist at UCLA. HE thinks maybe so.

“So the goal might be to create buzz. That if you only sell green light bulbs and a tofu turkey burger, people might say oh yeah, that’s the green place. But if you do some truly wacky stuff, generating this green buzz, might tip, that even a Dick Cheney might come with his grandson hearing that it’s this wacky.”

Which is more or less the point – Locali wants to recruit new green consumers. Consumers who right now live in neighborhoods that don’t really have supermarkets and so they buy most of their food at liquor and convenience stores.

Of course, one of the problems will probably be price. A 16 oz slushie at Locali is $5.49, while a 22 oz slurpee at 7-11 is just $1.40. But Kahn, the economist, thinks because Locali is smaller and more flexible than say a Whole Foods, it might actually have a better shot at making it in new neighborhoods.

“And so a smaller business might have to pay only a couple hundred thousand dollars rather then multi million dollars to build a big boxed store. And that lower fixed cost of entering a market makes it more likely that smaller green stores might experiment more.”

And apparently, the ecovenience experiment is something that a lot of people want to try. In the first six days of business, the owners received phone calls from people in Seattle and DC and cities all over Southern California. And they all asked the same thing: how soon can we open a locali in our local neighborhood.
