Hundreds of products with peanuts or peanut-butter have been yanked from
store shelves. That’s because of an outbreak of salmonella poisoning. Kyle
Norris has the latest on the outbreak:
We know the products include cookies, crackers, snack bars, cakes, candies,
ice cream—even pet foods are affected. And there’s a chance that
potentially-contaminated food is still sitting on store shelves. And maybe in
your pantry.
Matthew Boulton is an associate professor of epidemiology. He’s at the
University of Michigan School of Public Health. He says the testing of the
Georgia facility that made these peanut-butter products shows there are
flaws in the food safety system.
“I think one of the big problems is this divide we have between the folks who do the
regulation and the folks responsible for human health. Sometimes you don’t have good
communication between those two groups and it’s really critical if you’re going to get a
handle on insuring a safe food supply.”
Boulton says this peanut-butter scare could go on for a few weeks. Or a few
months.

In China, infant formulas contaminated with melamine killed four babies and made
thousands sick. The FDA said no amount was acceptable.
Then the FDA started secretly testing infant formulas made in the U.S. It found
melamine or a related chemical, cyanuric acid, in Nestle’s Good Start formula and
Mead Johnson’s Enfamil. ‘
Suddenly, the FDA decided a trace amount, one part per million is safe.
Lisa Madigan is the Attorney General for the State of Illinois. She says the FDA
should stop sales of those formulas.
“We have directly asked them to make sure these formulas are recalled as well as to
make sure that people across the country are aware of the problem.”
The FDA stresses levels of the chemicals in the U.S. infant formulas are more than
10,000 times lower than the levels reported in the Chinese formulas.

A group of New Yorkers is trying to convince people to get out on one of the most
polluted bodies of water in the country- literally out there, in canoes. Samara
Freemark reports that they hope once people see the water up close, they’ll realize
just how dirty it is. And maybe then they’ll help clean it up:
(sound of water, paddling)
You wouldn’t believe the stuff people have pulled out of the Gowanus Canal.
Refrigerators. Bathtubs, rusted cars. A 5000 pound dead whale. A suitcase full of
human body parts. Sewage floods into the canal all the time. So you see everything
people flush down their toilets. The water itself is a sickly, opaque green.
And that’s just the stuff you can see. The canal used to be a dumping ground for the
factories that line it. And the sediment at the bottom is still full of a laundry list of
toxic chemicals: cyanide, mercury, lead, asbestos. Scientists found strains of
gonorrhea in a water sample just last year.
And I’m sitting in a canoe in the middle of it.
(water noise, “Ewww, oh, God, gross. It’s like a subway down here.”)
The Gowanus is a 2 mile long trough of murky water that flows into the New York
Harbor – though the word ‘flowing ‘ is a bit optimistic, since the water mostly just sits
there.
You wouldn’t think anyone would want to canoe in this kind of water – much less
see it as a good way to spend a lazy summer afternoon.
(Laughs.) “ My first day was like, hell no. I knew it was going to be nasty.” (Laughs.)
That’s Alex Kovaleski. She’s a Dredger, a member of a group that gets together to
canoe the Gowanus.
“But I’m always looking for an adventure or a way to see things from a new
perspective, so I went out. And then I started having dreams about it, and it was all
over.”
Kovaleski knew she had to do something.
So almost every summer weekend she and the Dredgers gather at a makeshift pier
and paddle up and down the canal.
They invite others along. Anyone who shows up can jump in a borrowed canoe and
take it for a paddle. They get a lot of first-timers, New Yorkers who have heard about
the trips and come for the novelty or to get a taste of nature in this most urban of
cities.
That’s why Stephen Kline and Beatrice Aranow came. This is their first time at a
Dredgers event. I speak with them on the pier, before they step into a canoe. They
say they came because they love nature, they love being out on the water, and they
want to see their city from a whole new perspective.
Stephen and Beatrice are in for a big surprise. Twenty minutes later, they had their
new perspective.
(talking over each other) “ There were like dead rats, turds. It was a lot worse than I
could have ever imagined. It wasn’t that mysterious. I actually thought I was going
to have a pleasant time going out but it was pretty intense. It was repulsive.”
This doesn’t sound like a ringing endorsement of the Dredgers.
But Alex says Stephen and Beatrice’s reaction isn’t that bad – it’s actually kind of the
point.
“Part of it is just being out there with the poop and the trash, like, hah, here it is,
there’s no getting away from it. When you’re in it, you’re naturally longing to see it
restored.”
A week later I came back to the Gowanus canal for another Dredgers event. This
one’s a cleanup day, and volunteers are out with rubber gloves and bags, picking up
trash. It’s kind of a festive scene- there’s music and free pizza. And there’s a group of
high schoolers who came to spend the day canoeing and helping out.
(students talking about canoeing, cleaning)
Alex says those students are who the Dredgers really want to reach. The Gowanus
isn’t going to be clean anytime soon. But those kids are going to grow up, and they’re
going to be tax payers and voters. Soon they’re going to make the decisions that
decide the future of the canal.

More Americans have started
planting their own gardens in recent
years. But it turns out a lot of
urban gardens are contaminated with
lead. Julie Grant reports:
Last year 22% of Americans planted a garden.
Wendy Heiger-Bernays is professor of environmental health
at Boston University.
She says if you have an urban garden, she would expect to find heavy metals, especially lead, in the soil. It comes from old garbage, dripping oil, and peeling paint.
“Older homes have been demonstrated to leach lead from the home through the drip line and into the soil.”
Even small amounts of lead in the blood can cause learning disabilities in children.
Heiger-Bernays says you don’t have to throw away this year’s veggies. Just wash them well. And peel root vegetables.
And to get ready for next year, Heiger-Bernays says have your
soil tested. If there’s lead, add a foot of clean compost to the top of the garden bed. Next Spring plant only in that top layer.

Congress might vote this fall
on a plan to triple the amount of money
for cleaning up pollution hot spots
around the Great Lakes. Chuck Quirmbach
reports:
The Great Lakes Legacy Act is supposed to remove contaminated sediment from harbors.
But, clean-up has been slow because there’s not enough money.
Although tens of millions of dollars have been authorized in the past, Congress and the
Bush Administration have not actually spent much of it on clean up projects.
EPA regional administrator Lynn Buhl says despite the history of the Legacy Act, more
money should be authorized.
“First of all, there needs to be an appreciation of how many players are involved in these
projects. They don’t come together overnight. I think we’ve done well to have completed
five already.”
Congress could increase the amount of authorized spending from 54 million dollars a
year to 150 million per year.
The EPA acknowledges a potential tripling of the funds for the Great Lakes Legacy Act
might not sit well with some Congressional budget hawks.

A team at Tufts University is working on sensors that could change color to
tell you if a bag of lettuce has dangerous bacteria in it.
The special ingredient is silk. They boiled silkworm cocoons. And made a
thin silk film out of the proteins. The silk film has color changing properties
– like a butterfly’s wing.
Fio Omenetto is the lead researcher. He says it could be possible to activate
the film so it detects the presence of E. coli. Then the film could be put in a
bag of spinach.
“So immediately by looking at color change you will be able to tell whether
the spinach is good to eat or not.”
Omenetto says this is still pretty futuristic at this point. He says it’ll
probably be at least five years before you might see this at the grocery store.

During the past 35 years, people have been getting
sick from contaminated produce more often. That’s according
to a recent study from the Centers for Disease Control and
Prevention. Rebecca Williams reports:
After hundreds of people got sick from contaminated spinach and
lettuce, researchers started looking back at three decades of disease
cases. They found that people are getting sick from contaminated produce
more often. Bacteria such as E. coli and salmonella are often the cause.
Michael Lynch is one of the study’s authors. He says Americans are eating
more salads, but that doesn’t totally explain why there are more disease
outbreaks.
“We were a little surprised that that didn’t entirely explain the increase
but what else is contributing to that is not clear.”
Lynch says contamination can happen anywhere between the farm and your salad
plate. He says it’s important to thoroughly wash lettuce before eating it.
But he says that might not be enough to avoid getting sick.
He says stronger controls are needed at every step to try to prevent
contamination.

A virus that’s been killing fish in the Great Lakes is spreading to
other waterways in the US. Chuck Quirmbach reports:
Viral hemorrhagic septicemia has been limited to the eastern Great
Lakes region, but now it’s gotten into a forty-mile long lake in
Wisconsin. Lake Winnebago draws anglers from a wide area.
Mike Schmal is a local tourism official. He says the fish-killing
virus could be very disruptive.
“There’s numerous bait shops and numerous businesses that depend on the
lake and this is our summer leisure season… when the boating season
begins and when sportfishing begins.”
Scientists say it appears to be impossible to get the virus out of
infected waters, so natural resource officials are trying to stop VHS
from being spread to more lakes and rivers in other states.
It’s not clear how VHS got into the US, though contaminated
ballast water from international ships is one possibility.

Fish advisories are confusing. Their guidelines change depending on your gender and age,
and on the type of fish you’re eating. Reporter Kyle Norris boils down
some of the information in advisories and comes up with a few things to think about
when you eat fish:
So I did a little informal survey the other day where I asked my friends what they knew about
eating fish. Some of my friends said, “Hey, isn’t eating fish good for you?” Well, turns out they’re right. Fish are
great sources of protein. They’re low in “bad” fats and high in “good” fats, or omega-3
fatty acids, which help your heart stay healthy.
And some of my other friends knew that fish were bad for you. Turns out they’re also right. Fish
take in pollutants through their food and water. Toxins such as mercury, PCBs, and
dioxins. If humans eat enough contaminated fish, those contaminants can build up in our
bodies and cause serious health problems. Contaminants are especially threatening for
small children and women of childbearing age because they can affect children’s
developing nervous systems.
Governments put out advisories so we know which fish are safe to eat. But advisories aren’t
the easiest thing to understand. And anyway, what do you do if you’re in a restaurant, or
cruising through the grocery store and you just want some fish?
“Uh we’re standing in front of the seafood counter at Whole Foods and we’re looking at
our fresh case…”
That’s Nels Carlson. He heads up the seafood department at my local Whole Foods
Market. He says people ask him about fish safety everyday:
“It can be kind of a daunting topic, I think, because there is such a variety. It’s not just a
gross generalization. So it really, it takes a lot of dialogue between customers and team
members and having a very knowledgeable team member base here really helps that.”
They’ll ask him about mercury in the fish, a highly toxic metal that occurs naturally but is a lot more prevalent
mostly because of coal burning power plants. Mercury shows up in higher concentrations
in certain kinds of fish. It’s nice to have a knowledgeable guy like Nels to talk with. Good fish vendors, such as
Whole Foods, go through special training on fish safety. But what if there’s no seafood
expert hanging out next to the fish sticks in the freezer section, if you know what I mean?
Anita Sandretto teaches in the Environmental Health Sciences department at the
University of Michigan’s School of Public Health, and she said that my friends are right.
Okay, well, she didn’t really say that, but she said there are good things about fish and there are bad things about fish:
“If you want to have the benefit of the fat and the omega-3 fatty acids, eat fish with more
fat, but the fat will also be where you will see the contaminants such as PCBs, dioxin.
The flesh will also be where you might have the mercury contamination.”
See, that’s the thing about eating fish: it gets complicated and there are no hard and fast
rules. Sandretto says eating fish is all about treading a line between the advantages and
the risks. So, if there is a risk, you want to reduce it as much as possible:
“…Because if you have any risk in a particular type of food, if you only consume once in
while, you have a less risk of anything bad happening.”
So think in terms of moderation and variety. Sandretto says it’s cool if you want to eat fish once or
twice a week, and to try and vary the kinds of fish that you eat. She says moderation and
variety are actually great rules of thumb to apply to your entire diet. So you could eat a
turkey sandwich on white one day, tuna on whole wheat the next, and a veggie burger the day
after that.
If you eat fish caught from local waters, check with your regional or state health
departments for their fish advisories. Just because a waterway looks clean or is in a
picturesque setting does not mean that its fish are harmless. Contaminants enter the
water in all kinds of ways.
One last thought: imagine a little fish with a little bit of contamination in its body.
Now imagine a medium-sized fish, who swims along and eats that fish and 99 of its closest small
fish friends. That medium guy now has 100 times more contamination than the small fish.
And now let’s say a big fish swims up and gulps down ten medium fish. That big fish has a
concentration that’s 1000 times higher than what that origianal small fish had.
So the moral of that story is, eat smaller fish when possible, also called pan fish. And
at the end of the day, keep in mind that the majority of research, including a recent study
from Harvard’s School of Public Health, say that the benefits of eating fish in moderation
outweigh the risks.
Water diversion is an increasing threat to the Great Lakes. As communities grow so does the demand. (Photo by Brandon Bankston)

We’re continuing the series Ten Threats to the Great Lakes. Our field
guide through the series is Lester Graham. He says our next report looks
at where the demand for water will be greatest.
Right around the Great Lakes is where there’s going to be more demand
for drinking water. Water officials say as cities and suburbs grow, so
does the need for water. Some towns very near the Great Lakes say they
need lake water right now, but in some cases they might not get it. The
Great Lakes Radio Consortium’s Christina Shockley reports:
People who live around the Great Lakes have long used the lakes’ water
for transportation, industry, and drinking water. Most of the water we
use, gets cleaned up and goes back in the lakes.
That’s because the Great Lakes basin is like a bowl. All the water used
by communities inside that bowl returns to the lakes in the form of
groundwater, storm water runoff, and treated wastewater, but recently, thirsty
communities just outside the basin—outside that bowl—have shown an
interest in Great Lakes water.
Dave Dempsey is a Great Lakes advisor to the environmental group
“Clean Water Action.”
“We are going to be seeing all along the fringe areas of the Great Lakes
basin all the way from New York state to Minnesota, communities that
are growing and have difficulty obtaining adequate water from nearby
streams or ground water.”
Treated water from those communities won’t naturally go back to the
basin. Treated wastewater and run-off from communities outside the
Great Lakes basin goes into the Mississippi River system, or rivers in the
east and finally the Atlantic Ocean.
The Great Lakes are not renewable. Anything that’s taken away has to be
returned. For example, when nature takes water through evaporation, it
returns it in the form of rain or melted snow. When cities take it away, it
has to be returned in the form of cleaned-up wastewater to maintain that
careful balance.
Dave Dempsey says the lakes are like a big giant savings account, and
we withdraw and replace only one percent each year.
“So, if we should ever begin to take more than one percent of that
volume on an annual basis for human use or other uses, we’ll begin to
draw them down permanently, we’ll be depleting the bank account.”
Some of the citiesthat want Great Lakes water are only a few miles from
the shoreline. One of the most unique water diversion requests might come
from the City of Waukesha, in southeastern Wisconsin. The city is just 20 miles
from Lake Michigan. Waukesha is close enough to smell the lake, but it
sits outside the Great Lakes basin. Waukesha needs to find another
water source because it’s current source – wells—are contaminated with
radium.
Dan Duchniak is Waukesha’s water manager. He says due to the city’s
unique geology, it’s already using Great Lakes water. He says it taps an
underground aquifer that eventually recharges Lake Michigan.
“Water that would be going to Lake Michigan is now coming from Lake
Michigan…. our aquifer is not contributing to the Great Lakes any more,
it’s pulling away from the Great Lakes.”
Officials from the eight Great Lakes states and Ontario and Quebec
recently approved a set of rules that will ultimately decide who can use
Great Lakes water. The new rules will allow Waukesha—and some
other communities just outside the basin—to request Great Lakes water,
and drafters say Waukesha will get “extra credit” if it can prove it’s
using Lake Michigan water now.
Environmentalists are still concerned that water taken from the Lakes be
returned directly to the Lakes, but some say even that could be harmful.
Art Brooks is a Professor of Biological Sciences at the University of
Wisconsin- Milwaukee. He says the water we put back still carries some
bi-products of human waste.
“No treatment plant gets 100 percent of the nutrients out of the water,
and domestic sewage has high concentrations of ammonia and
phosphates. Returning that directly to the lake could enhance the growth
of algae in the lake.”
That pollution could contribute to a growing problem of dead zones in
some areas of the Great Lakes. Brooks and environmentalists concede
that just one or two diversions would not harm the Great Lakes, but they
say one diversion could open the floodgates to several other requests, and
letting a lot of cities tap Great Lakes water could be damaging.
Derek Sheer of the environmental group “Clean Wisconsin” says some
out-of-basin communities have already been allowed to tap Great Lakes
water under the old rules.
“The area just outside of Cleveland–Akron, Ohio– has a diversion
outside of the Great Lakes basin, so they’re utilizing Great Lakes water
but they’re putting it back.”
There are several communities that take Great Lakes water, but they, too,
pump it back. The new water rules still need to be ok-ed by the legislature of
each Great Lakes state, and Congress. Since the rules are considered a
baseline, environmental interests throughout the region say they’ll lobby
for even stricter rules on diversions.
