Crops, Ponds Destroyed in Quest for Food Safety

Dick Peixoto planted hedges of fennel and flowering cilantro around his
organic vegetable fields in the Pajaro Valley near Watsonville to
harbor beneficial insects, an alternative to pesticides.

He has since ripped out such plants in the name of food safety,
because his big customers demand sterile buffers around his crops. No
vegetation. No water. No wildlife of any kind.

"I was driving by a field where a squirrel fed off the end of the
field, and so 30 feet in we had to destroy the crop," he said. "On one
field where a deer walked through, didn't eat anything, just walked
through and you could see the tracks, we had to take out 30 feet on
each side of the tracks and annihilate the crop."

In the verdant farmland surrounding Monterey Bay, a national marine
sanctuary and one of the world's biological jewels, scorched-earth
strategies are being imposed on hundreds of thousands of acres in the
quest for an antiseptic field of greens. And the scheme is about to go

Invisible to a public that sees only the headlines of the latest
food-safety scare - spinach, peppers and now cookie dough - ponds are
being poisoned and bulldozed. Vegetation harboring pollinators and
filtering storm runoff is being cleared. Fences and poison baits line
wildlife corridors. Birds, frogs, mice and deer - and anything that
shelters them - are caught in a raging battle in the Salinas Valley
against E. coli O157:H7, a lethal, food-borne bacteria.

In pending legislation and in proposed federal regulations, the push
for food safety butts up against the movement toward biologically
diverse farming methods, while evidence suggests that industrial
agriculture may be the bigger culprit.

'Foolhardy' approach

"Sanitizing American agriculture, aside from being impossible, is
foolhardy," said UC Berkeley food guru Michael Pollan, who most
recently made his case for smaller-scale farming in the documentary
film "Food, Inc." "You have to think about what's the logical end point
of looking at food this way. It's food grown indoors hydroponically."

Scientists do not know how the killer E. coli pathogen, which dwells
mainly in the guts of cattle, made its way to a spinach field near San
Juan Bautista (San Benito County) in 2006, leaving four people dead, 35
with acute kidney failure and 103 hospitalized.

The deadly bug first appeared in hamburger meat in the early 1980s
and migrated to certain kinds of produce, mainly lettuce and other
leafy greens that are cut, mixed and bagged for the convenience of
supermarket shoppers. Hundreds of thousands of the bug can fit on the
head of a pin; as few as 10 can lodge in a salad and end in lifelong
disability, including organ failure.

Going national

For many giant food retailers, the choice between a dead pond and a
dead child is no choice at all. Industry has paid more than $100
million in court settlements and verdicts in spinach and lettuce
lawsuits, a fraction of the lost sales involved.

Galvanized by the spinach disaster, large growers instituted a
quasi-governmental program of new protocols for growing greens safely,
called the "leafy greens marketing agreement." A proposal was submitted
last month in Washington to take these rules nationwide.

A food safety bill sponsored by Rep. Henry Waxman, D-Los Angeles,
passed this month in the House Energy and Commerce Committee. It would
give new powers to the Food and Drug Administration to regulate all
farms and produce in an attempt to fix the problem. The bill would
require consideration of farm diversity and environmental rules, but
would leave much to the FDA.

An Amish farmer in Ohio who uses horses to plow his fields could
find himself caught in a net aimed 2,000 miles away at a feral pig in
San Benito County. While he may pick, pack and sell his greens in one
day because he does not refrigerate, the bagged lettuce trucked from
Salinas with a 17-day shelf life may be considered safer.

The leafy-green agreement is based on available science, but it is just a jumping-off point.

Large produce buyers have compiled secret "super metrics" that go
much further. Farmers must follow them if they expect to sell their
crops. These can include vast bare-dirt buffers, elimination of
wildlife, and strict rules on water sources. To enforce these rules,
retail buyers have sent forth armies of food-safety auditors, many of
them trained in indoor processing plants, to inspect fields.

Keeping children out

"They're used to working inside the factory walls," said Ken Kimes,
owner of New Natives farms in Aptos (Santa Cruz County) and a board
member of the Community Alliance With Family Farmers, a California
group. "If they're not prepared for the farm landscape, it can come as
quite a shock to them. Some of this stuff that they want, you just
can't actually do."

Auditors have told Kimes that no children younger than 5 can be
allowed on his farm for fear of diapers. He has been asked to issue
identification badges to all visitors.

Not only do the rules conflict with organic and environmental
standards; many are simply unscientific. Surprisingly little is known
about how E. coli is transmitted from cow to table.

Reducing E. coli

Scientists have created a vaccine to reduce E. coli in livestock,
and a White House working group announced plans Tuesday to boost safety
standards for eggs and meat. This month, the group is expected to issue
draft guidelines for reducing E. coli contamination in leafy greens,
tomatoes and melons.

Some science suggests that removing vegetation near field crops
could make food less safe. Vegetation and wetlands are a landscape's
lungs and kidneys, filtering out not just fertilizers, sediments and
pesticides, but also pathogens. UC Davis scientists found that
vegetation buffers can remove as much as 98 percent of E. coli from
surface water. UC Davis advisers warn that some rodents prefer cleared

Produce buyers compete to demand the most draconian standards, said
Jo Ann Baumgartner, head of the Wild Farm Alliance in Watsonville, so
that they can sell their products as the "safest."

State agencies responsible for California's water, air and wildlife
have been unable to find out from buyers what they are demanding.

They do know that trees have been bulldozed along the riparian
corridors of the Salinas Valley, while poison-filled tubes targeting
rodents dot lettuce fields. Dying rodents have led to deaths of owls
and hawks that naturally control rodents.

Unscientific approach

"It's all based on panic and fear, and the science is not there,"
said Dr. Andy Gordus, an environmental scientist with the California
Department of Fish and Game.

Preliminary results released in April from a two-year study by the
state wildlife agency, UC Davis and the U.S. Department of Agriculture
found that less than one-half of 1 percent of 866 wild animals tested
positive for E. coli O157:H7 in Central California.

Frogs are unrelated to E. coli, but their remains in bags of
mechanically harvested greens are unsightly, Gordus said, so "the
industry has been using food safety as a premise to eliminate frogs."

Farmers are told that ponds used to recycle irrigation water are
unsafe. So they bulldoze the ponds and pump more groundwater, opening
more of the aquifer to saltwater intrusion, said Jill Wilson, an
environmental scientist at the Central Coast Regional Water Quality
Control Board in San Luis Obispo.

Wilson said demands for 450-foot dirt buffers remove the agency's
chief means of preventing pollution from entering streams and rivers.
Jovita Pajarillo, associate director of the water division in the San
Francisco office of the Environmental Protection Agency, said removal
of vegetative buffers threatens Arroyo Seco, one of the last remaining
stretches of habitat for steelhead trout.

Turning down clients

"It's been a problem for us trying to balance the organic growing
methods with the food safety requirements," Peixoto said. "At some
point, we can't really meet their criteria. We just tell them that's
all we can do, and we have to turn down that customer."

Large retailers did not respond to requests for comment. Food trade
groups in Washington suggested calling other trade groups, which didn't

Chiquita/Fresh Express, a large Salinas produce handler, told the
advocacy group Food and Water Watch that the company has "developed
extensive additional guidelines for the procurement of leafy greens and
other produce, but we consider such guidelines to be our confidential
and proprietary information."

Seattle trial lawyer Bill Marler, who represented many of the
plaintiffs in the 2006 E. coli outbreak in spinach, said, "If we want
to have bagged spinach and lettuce available 24/7, 12 months of the
year, it comes with costs."

Still, he said, the industry rules won't stop lawsuits or eliminate
the risk of processed greens cut in fields, mingled in large baths, put
in bags that must be chilled from packing plant to kitchen, and shipped
thousands of miles away.

"In 16 years of handling nearly every major food-borne illness
outbreak in America, I can tell you I've never had a case where it's
been linked to a farmers' market," Marler said.

"Could it happen? Absolutely. But the big problem has been the
mass-produced product. What you're seeing is this rub between trying to
make it as clean as possible so they don't poison anybody, but still
not wanting to come to the reality that it may be the industrialized
process that's making it all so risky."

Some major recent outbreaks of food-borne illness

Food and Drug Administration lists 40 food-borne pathogens. Among the
more common: E-coli O157:H7, salmonella, listeria, campylobacter,
botulism and hepatitis A.

June 2009: E. coli O157:H7 found in Nestle Toll
House refrigerated cookie dough manufactured in Danville, Va., resulted
in the recall of 3.6 million packages. Seventy-two people in 30 states
were sickened. No traces found on equipment or workers; investigators
are looking at flour and other ingredients.

October 2008: Salmonella found in peanut butter
from a Peanut Corp. of America plant in Georgia. Nine people died, and
an estimated 22,500 were sickened. Criminal negligence was alleged
after the product tested positive and was shipped.

June 2008: Salmonella Saintpaul traced to serrano
peppers grown in Mexico. More than 1,000 people were sickened in 41
states, with 203 reported hospitalizations and at least one death.
Tomatoes were suspected, devastating growers.

April 2007: E. coli O157:H7 found in beef, sickening 14 people. United Food Group recalled 5.7 million pounds of meat.

December 2006: E. coli O157:H7 traced to Taco Bell
restaurants in New Jersey and Long Island, N.Y. Green onions suspected,
then lettuce. Thirty-nine people were sickened, some with acute kidney

September 2006: E. coli O157:H7 found in Dole
bagged spinach processed at Earthbound Farms in San Juan Bautista (San
Benito County). The outbreak killed four people, sent 103 to hospitals,
and devastated the spinach industry.
