Animal research labs usually get rid of carcasses by burning them in incinerators. Now, a new more environmentally friendly technology is being used to dispose of the diseased dead animals and the lab supplies they contaminate. The new method has worked well enough that hospitals are considering it as a way to dispose of medical waste. The Great Lakes Radio Consortium’s Julie Halpert reports:

Animal research labs usually get rid of carcasses by burning them in incinerators. Now, a new more environmentally friendly technology is being used to dispose of the diseased dead animals and the lab supplies they contaminate. The new method has worked well enough that hospitals are considering it as a way to dispose of medical waste. The Great Lakes Radio Consortium’s Julie Halpert reports:


Until recently, the only safe way to destroy diseased tissue and other infectious waste was to burn it in an incinerator. But dangerous chemicals such as dioxins spew from the incinerator smokestacks, and burning leaves behind a toxic ash.


(sound of machine whirring)


Now, there’s an alternative to burning. Dr. Gordon Kaye stands in a spotless room beside one of the units manufactured at a company he helped found, WR Squared, in Indianapolis, Indiana. The unit will eventually be used to dispose of 5,000 pounds of dead animals – about the equivalent of five large cows – that were used for veterinary research.


But there will be no smoke. There’ll be no fire.


Kaye’s idea for a new type of disposal technology began 12 years ago when he was a pathology professor at Albany Medical College. He was frustrated with how much it cost to dispose of dead research animals. So, he started experimenting with a new technology. And alkaline hydrolysis was born.


“Well, there are no air emissions from it. It’s a sealed system. It takes place in a hermetically sealed pressure vessel. No dangerous products are produced in it because of the temperature which it takes place.”


Alkaline hydrolysis works like this: infectious waste goes into a tightly sealed vessel, along with strong alkalis which are very caustic. The waste is then cooked at temperatures well above boiling. A chemical reaction causes the waste to break down. The infectious components are neutralized. When it’s over, you end up with two products: a sterile, water-like solution, that can head to a sanitary sewer system, and sterile crushed bones, the consistency of powder, that can be used as fertilizer. Because the end products are clean, they don’t require complicated disposal, so the process is cheaper than incineration.


WR squared now has 60 units in 15 states, primarily at research facilities. The U.S. Department of Agriculture has purchased several of them. New York was the first state to allow use of the technology. Ira Salkin directed that state’s medical waste program when it approved WR squared’s process.


“It has less potential problems than is being found with incineration and the use of incineration in the U.S. is decreasing and therefore their system holds great promise. As the numbers of incinerators decrease, one finds they have this alternative to be used to treat pathologic material.”


Environmentalists agree with Salkin that the technology is sound. Horhay Emmanuel is with Health Care Without Harm. He notes that it’s especially effective for one troublesome type of waste, cattle dead from Mad Cow disease.


“Not only does it destroy infectious agents, but it also destroys prion-contaminated waste. And prions are what are believed to cause things like Mad Cow disease, which are difficult to destroy, even by incineration, so WR squared has been shown to destroy these prions in the contaminated waste.”


Last April, The Environmental Protection Agency approved alkaline hydrolysis, along with incineration, as a way to treat Mad Cow diseased waste. And WR Squared’s Gordon Kaye sees that as a big future market.


Horhay Emmanuel, with Health Care Without Harm, says while alkaline hydrolysis is generally good for the environment, there is one concern. The fluid that’s produced could overwhelm some small town’s sewer systems. The company says in communities with small sewer systems, the solution can be released more slowly or during off-peak hours.


So, alkaline hydrolysis process is cheaper, it pollutes less, government agencies like it, and environmentalists find little to criticize.
Now, the company is broadening its reach to treat hospital waste. Many hospitals are using smaller, not very efficient incinerators that pollute more.


WR Squared’s Gordon Kaye says he expects big growth with this new method to dispose of medical and infectious waste as labs and hospitals look for ways to replace their incinerators over the next several years.

Chronic Wasting Disease Spreading in Region

This hunting season, there’s a lot more testing for a disease that’s killing deer in parts of
the Great Lakes region. The Great Lakes Radio Consortium’s Lester Graham reports:


Chronic Wasting Disease is similar to Mad Cow Disease. In this instance, it attacks deer
and elk, causing them to waste away, become disoriented, and eventually die. It’s been
found in captive animals in Minnesota, in the wild deer population in Wisconsin and just
recently a deer in Illinois was found to have Chronic Wasting Disease. Carol Knowles is
with the Illinois Department of Natural Resources. She says about 4,000 samples of
tissue from deer are being taken during the hunting season. They’ll be sent to labs to see
how far the disease has spread in that state. But because the labs are being swamped with samples, it
will take a while before anything is known.


“It will take months to get all of those results back, yes. But we hope to expedite the ones in northern Illinois where we know we had at least one
confirmed case.”


Other Great Lakes states are also testing for Chronic Wasting Disease in their deer herds,
hoping to stop the disease from spreading quickly.

Grass-Fed Beef Good for Business?

Most of the cattle raised in the Great Lakes region spend their lives in a feedlot, fattening up on corn and other grains before becoming dinner themselves… but there’s a growing number of organic farmers looking at putting their cows in the pasture.

Most of the cattle raised in the Great Lakes region spend their lives in a feedlot, fattening up on
corn and other grains before becoming dinner themselves. But there’s a growing number of
organic farmers looking at putting their cows in the pasture. They say grass-fed beef is a healthy
alternative. Brad Linder has more:


(Sound of cows mooing)


Here on Natural Acres Farm in Millersburg, in Central Pennsylvania, 120 cows have their heads
to the ground. They’re chewing on tender shoots of grass instead of ground corn or some mixture
of grain feed.


Steve Shelley is in charge of marketing beef for Natural Acres. He says cows are designed to eat
grass, but most farmers today find it cheaper and easier to buy commercial feed made from grains
like corn.


“You know farmers nowadays. Well that’s the way their dads did it, so they’re doing the same
thing. It’s much easier to go out and dump a bucket of feed into a pen for that animal to eat than
it is for that animal to be out, to get the best benefit from the soil.”


And Shelley says another reason most farmers use grain feed is that it takes longer to raise cattle
on grass. Grain-fed cows are ready for slaughter within a year, but Natural Acres cows can take
six months to a year longer to reach the same size.


But Shelley says that convenience for the farmer comes at a cost to the cattle. Shelley says cows
raised on corn get sick more often than grass-fed cattle. As preventative measures, cows
traditionally have antibiotics mixed in with their feed and require frequent visits from the
veterinarian.


Cows on organic farms are naturally healthier. And since Shelley’s marketing his product to
consumers interested in “healthier meat,” the animals also don’t receive growth hormones or other
chemicals often found in commercial beef.


Natural Acres runs an organic foods shop on-site. But Shelley says the market for such products
is pretty small in rural Central Pennsylvania. Most of the beef isn’t sold here. Instead, much of it
is shipped to restaurants and stores, where people are willing to pay premium prices.


“In a grocery store, you may pay anywhere from a $1.75/pound to $2.00 for a pound of beef.
Retail, we get $4.09.”


Being able to charge more for beef is only one of the perks to raising cattle on grass. The farmers
who raise grass-fed beef don’t have to pay as much to the veterinarian.


“The animals rarely get sick. And I have talked to hundreds of people who raise animals on
pasture.”


Jo Robinson is author of the book, “Why Grass Fed is Best.” She also runs the website
‘eatwild.com,’ which compiles research on grass-fed cattle.


“The big surprise, I think – and this wasn’t known until about 1998 – is that an animal raised on
pasture has five times the amount of cancer fighting fat called conjugated linoleic acid, or CLA.”


Robinson says CLA helps prevent cows from developing tumors. There is some evidence
suggesting CLA has the same effect on humans, but it’s not yet clear if eating grass-fed beef is a
way for people to fight off cancer.


Robinson does point out that CLA is just one of the reasons there’s a growing demand for grass-
fed beef.


“Some people gravitate towards pasture finished meat because it’s free of hormones and
antibiotics. Some people are aware of the nutritional benefits. They like the fact that it’s lower in
saturated fat, higher in omega 3 fatty acids, higher in vitamin E, and a number of other
substances. It’s simply a healthier product all around.”


Robinson says she first started looking for American grass-farmers in 1997, and only found about
sixty. Now, she says, the market has grown to include at least ten times that number, which still
only represents a small portion of the American Beef Industry.


Paul Slayton is director of the Pennsylvania Beef Council, the non-profit organization charged
with promoting the state’s beef industry. Slayton says less than 1% of the state’s beef production
comes from grass farms. But he says those farms do fill an important role.


“I see it being a very viable part of our production in this part of the country, because we have
such an eclectic consumer group. And there are some consumers that just won’t eat anything else
but organic. And somebody’s going to be providing their food.”


As the beef industry is recovering from public concern over mad cow disease and e. coli bacteria,
Slayton says anything that convinces people meat is safe is fine by him.


And as for the taste of grass-fed beef, Steve Shelley from Natural Acres Farm says it might be
more familiar than many people think.


“Many times when I go and do a taste test at a store or something, a lot of the older people, when
they try it, make the comment: ‘This tastes like beef used to taste.'”


Shelley says the meat is leaner and can be tougher if cows aren’t fed a little grain before slaughter.
But Natural Acres is experimenting with different types of grass that might lend a more
consumer-friendly texture to the beef.


Shelley says it’s a combination of taste and nutrition that gets most people interested, even some
people who had given up on commercial beef altogether. Shelley tells one story about a man
who’s wife had banned meat from their house for five years.


“So he bought a hamburger and finally got her to try it, and at the end of the day, he gave me a high five, and he said, ‘I can eat beef
again! She’s given me permission to bring beef into the house!’ Well, that really makes you feel
good.”


So grass-fed beef is entering households that hadn’t seen any beef in a while for environmental
reasons or because of health concerns. While the beef might be a taste of days gone by, organic
farmers are getting better prices for their meat than even in the best of days past.

Aftermath of Chronic Wasting Disease

Wildlife managers in Wisconsin are facing a daunting task… how to dispose of thousands of potentially infectious deer carcasses. The Great Lakes Radio Consortium’s Gil Halsted reports:

Transcript

Wildlife managers in Wisconsin are facing a daunting task… how to dispose of thousands of potentially infectious deer carcasses. The Great Lakes Radio Consortium’s Gil Halsted reports:


Eighteen deer have tested positive for chronic wasting disease in an area of southwestern Wisconsin. To keep the disease from spreading, the state plans to kill 30-thousand deer in the area. But because the disease is related to mad cow disease, county landfills are refusing to bury the deer carcasses. The fear is that the mutant protein known as a prion that causes the disease could seep out of the landfill and pose a threat to human health.


Topf Wells is a spokesperson for Dane County, one of several counties that have refused to accept carcasses.


“The problem that many people are concerned about is that these prions are probably not destroyed by the forces in a landfill that lead to the decomposition of a lot of material.”


If counties don’t change their minds, the state may have to store thousands of deer carcasses in cold storage units during this fall’s hunt. Incinerating carcasses is another option. But at 75 dollars a deer it could prove too costly.

WHAT IS CHRONIC WASTING DISEASE? (Part 1)

Wildlife officials in the Midwest are battling the appearance of a deadly illness found in elk and deer. Called chronic wasting disease, or CWD, this ailment attacks an animal’s brain, slowly eating away healthy tissue. Several captive elk herds in the western U.S. and Canada have been infected with chronic wasting disease. Those herds have now been quarantined, but not before other animals from those herds were sold to farmers in 21 states nationwide, including several in the Midwest. The Great Lakes Radio Consortium’s Todd Melby has this first report of a two-part series:

Wildlife officials in the Midwest are battling the appearance of a deadly illness found in elk and deer. Called chronic wasting disease, or CWD, this ailment attacks an animal’s brain, slowly eating away healthy tissue. Several captive elk herds in the western U.S. and Canada have been infected with chronic wasting disease. Those herds have now been quarantined, but not before other animals from those herds were sold to farmers in 21 states nationwide, including several in the Great Lakes region. The Great Lakes Radio Consortium’s Todd Melby reports.


Chronic wasting disease is a neurological disorder. That means it affects the nervous system of elk and deer. It’s related to a number of other conditions, including scrapies in sheep and mad cow disease. Humans can also contract something similar — it’s called Creutzfeldt-Jakob disease.


All these conditions are related — and that’s making some health officials nervous. That’s because at least one, mad cow, can be transferred to humans. Dennis Stauffer is a spokesman for the Minnesota Department of Natural Resources. He says now more and more people are also keeping an eye on CWD.


“It’s been called the mad cow disease of deer. It is certainly similar biologically. There are also some important differences. Unlike mad cow disease, or CWD as we call it, we don’t yet have any evidence it is transmittable to humans. So that particular health risk is not confirmed.”


But that doesn’t stop people from worrying.


In the 1990s, mad cow disease in Great Britain triggered a similar ailment in humans, eventually killing dozens of people. But public health officials downplayed that possibility, leading to less vigilance in eliminating mad cow. Some people now say the same thing is happening here with CWD. Sheldon Rampton is the author of “Mad Cow U.S.A.”


“You are getting the same pattern of reassurances. The same pattern of government authorities and government scientists coming forward and not quite saying there is no danger, but saying they don’t see any evidence of danger. And then saying that in such a way that the public is led to believe that absence of evidence is evidence of absence.”


One of the problems is, little is known about the disease. Kris Petrini is a veterinarian with the Minnesota Board of Animal Health.


“We don’t know exactly what the incubation period is. We don’t know the youngest possible time an animal can get infected. The testing itself, right now, the only test we have that we can do is the animal has to be sacrificed and the brain tested.”


The outward signs of CWD aren’t exhibited until death is near. Again, Dennis Stauffer of the Minnesota DNR.


“Well, if you were to see a picture of one of these animals, they would be stumbling around, they would look wasted away. In advance stages, they would look disoriented, they would tend not to fear humans. They would look very, very sick and it would be very obvious that they are sick animals.”


Since learning that 36 elk from CWD-infected herds in Colorado and Canada were imported to Minnesota, state officials have set up a voluntary CWD surveillance program. All herds with exposed animals are participating in the program. Of the elk tested for CWD so far, none have had CWD.


(sound from Spooner, Wisconsin deer testing station: Cars on nearby two-lane highway.)


In neighboring Wisconsin, state officials are aggressively testing for CWD. On the opening weekend of deer hunting season, veterinarians took hundreds of brain samples from dead animals at locations throughout the state. In previous years, such efforts turned up no cases of CWD in the wild deer population, just like Minnesota. Ken Jonas is a wildlife biologist with the Wisconsin Department of Natural Resources.


“Right now, I’m not too concerned. If I were in Colorado or perhaps Wyoming or a state that was near to a chronic infection, I would be very concerned.”


While Kris Petrini, the Minnesota veterinarian, understands CWD hasn’t made it into the wild deer population, she says she wouldn’t be surprised to find it among the captive elk population in the state.


“No, not completely. Not with the number of elk we have and the amount of trading that goes on in the industry, I think it is highly possible that we will find chronic wasting disease.”


Six western states are home to elk herds with CWD infections. Elk farmers in another 15 states — including Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio and Pennsylvania — own animals from the original infected herds. So far, tests haven’t turned up any traces of CWD in herds with exposed animals in those states.

KEEPING AN EYE ON CHRONIC WASTING DISEASE (Part 2)

Several captive elk in Colorado have tested positive for chronic wasting disease. This fatal neurological ailment attacks an animal’s brain, slowly eating away healthy tissue. Chronic wasting disease, or CWD, has also spread to the wild deer population near the Colorado and Wyoming border. That’s prompted wildlife officials in the Midwest to begin looking for CWD in their wild deer herds. In the second of a two-part series, the Great Lakes Radio Consortium’s Todd Melby visited one such testing site in rural Wisconsin and filed this report:

The opening of the deer-hunting season in Wisconsin is a big day for Pauline Nol. But it’s not because she’s a hunter. Nol is a veterinarian. Instead of wearing a blaze orange vest, Nol sports a blue Dickie jumpsuit. She’ll need it to keep the blood of dead deer from staining her clothes.


(sound of medical instruments, followed by background sound of Nol and another vet moving instruments around on a table)


Nol and another veterinarian are arranging medical instruments on a folding table. It’s the kind of portable table you might find in a school cafeteria or church basement. Only today, the table is set up outside, in the parking lot of a Department of Natural Resources building just outside Spooner, a small town in northwestern Wisconsin.


In about a half hour, hunters will be pulling up in their pickup trucks to register deer they’ve shot just this morning. When they do, Nol, who works at the Department of Interior’s National Wildlife Health Center, will ask hunters if she might take a few samples from the carcass. The purpose: To check for chronic wasting disease.


Chronic wasting disease is a fatal neurological illness that is part of the same family of diseases as scrapies in sheep, mad cow disease in cattle and Creutzfeldt-Jakob disease in humans. CWD destroys a deer’s brain and is always fatal. Before death, the infected animal seems listless, confused and often stumbles around aimlessly.


There is concern among some people that CWD may be transmittable to humans. Yet many states in the Great Lakes region, such as nearby Minnesota, have just begun testing for CWD in wild deer herds. While it still seems limited to captive herds, officials are worried the disease could spread. Dennis Stauffer is a spokesman for the Minnesota DNR.


“The greatest problem, we think, in terms of not just the animals but in terms of human health is if this gets into the wild population. That would be, I think, very problematic. Because then once it’s no longer just limited to captive animals, then you have a real issue of how in the world do you get to it and eradicate it.”


In Wisconsin, veterinarians like Nol, have been testing dead deer since 1999. So far, the news has been good. No cases of CWD have been detected in the state’s wild deer herds.


(sound from deer testing station: Cars on nearby two-lane highway)


Back at the parking lot, employees are now ready to tag incoming deer. And that’s got Nol busy too. She strolls over to a couple standing next to a dead buck resting its head on the tailgate of a red pickup.


“Who got the deer this morning? That would be you? Congratulations. That’s great, that’s really great. So, we’re doing some sampling for looking at different diseases in the deer herd. So we’re wondering if we could take some samples from your deer?”


The pair agrees and Nol gets busy. The first thing she does is pull the deer’s head beyond the edge of the tailgate. And then she begins slicing through the fur and into the neck.


“What I’m doing is I’m making a cut in the neck just behind the jaw line. And that exposes the base of the brain, the brain stem and those lymph nodes we’re looking for.”


The lymph nodes are tested for bovine tuberculosis, or TB, a disease that’s been found in Michigan’s free-ranging deer herd since 1994. Wisconsin began testing deer for TB in 1996 and has yet to find an incidence of the disease.


The man who shot the deer is Tom Hack of Hartford, Wisconsin. Once the brain stem, lymph nodes and blood samples are analyzed back at Nol’s lab, Hack will be notified of the results.


There’s been no evidence linking CWD to humans. However, the state is testing deer for diseases and I ask Hack if that gives him pause.


“Well, sure. If I’m going to be eating the meat. Yeah, yeah it would worry me.”


“So, are you going to wait until you get the postcard back before you eat the meat?”


“No, I don’t think so.”


A little later, I catch up with Ken Jonas. He’s a wildlife biologist with the state DNR. This morning, he shot a deer himself. And now he’s tagging animals nabbed by other hunters. I ask him if hunters should wait until they receive their postcards back in the mail before eating the meat.


“No. Again, we consider all the deer currently to be safe in the state of Wisconsin. The monitoring is being done to determine if there is a problem at this point in time. We have no detects of either of those diseases in the wild herd.”


The reason for the testing, Jonas says, isn’t to let individual hunters know of a personal health risk, but to see if CWD has found its way into the state’s wild deer herds. For the Great Lake Radio Consortium, I’m Todd Melby in Minneapolis.

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.

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.

Warning Labels for French Wine?

Warning labels on cigarettes and alcohol alert consumers to
