FREDERICKSBURG, Pa. — The smell of oregano wafting from Scott Sechler’s office is so strong that anyone visiting Bell & Evans these days could be forgiven for wondering whether Mr. Sechler has forsaken the production of chicken and gone into pizza.

The experience of Scott Sechler, Bell & Evans’s owner, with using oregano oil led to a test at Country View Family Farms.

Over the last six months, about 5,000 pigs at Country
View Family Farms have eaten feed laced with By-O-Reg after being
weaned from their mothers.
Oregano lies loose in trays and tied into bunches on tabletops and
counters, and a big, blue drum that held oregano oil stands in the
corner. “Have you ever tried oregano tea?” Mr. Sechler asked, mashing
leaves between his broad fingers.
Off and on over the last three years or so, his chickens have been eating a specially milled diet
laced with oregano oil and a touch of cinnamon. Mr. Sechler swears by
the concoction as a way to fight off bacterial diseases that plague meat
and poultry producers without resorting to antibiotics, which some experts say can be detrimental to the humans who eat the meat. Products at Bell & Evans,
based in this town about 30 miles east of Harrisburg, have long been
free of antibiotics, contributing to the company’s financial success as
consumers have demanded purer foods.
But Mr. Sechler said that nothing he had used as a substitute in the past worked as well as oregano oil.
“I have worried a bit about how I’m going to sound talking about this,”
he said. “But I really do think we’re on to something here.”
Skeptics of herbal medicines abound, as any quick Internet search
demonstrates. “Oil of oregano is a perennial one, advertised as a cure
for just about everything,” said Scott Gavura, a pharmacist in Toronto
who writes for the Web site Science-Based Medicine.
“But there isn’t any evidence, there are too many unanswered questions
and the only proponents for it are the ones producing it.”
Nonetheless, Mr. Gavura said he would welcome a reduction in the use of antibiotics in animals.
At the same time, consumers are growing increasingly sophisticated about the content of the foods that they eat.
Data on sales of antibiotic-free meat is hard to come by, but the sales
are a tiny fraction of the overall meat market. Sales in the United
States of organic meat, poultry and fish, which by law must be raised
without antibiotics, totaled $538 million in 2011, according to the
Organic Trade Association. By comparison, sales of all beef that year
were $79 billion.
Still, retailers like Costco, Whole Foods and Trader Joe’s, as well as
some restaurant chains, complain that they cannot get enough
antibiotic-free meat.
Noodles & Company,
a fast-growing chain of more than 300 restaurants, recently added
antibiotic-free pork to the choices of ingredients that customers can
add to their made-to-order pastas. It ensured its supply by ordering
cuts of meat that were not in relatively high demand and by committing
in advance to buy a year’s worth, said Dan Fogarty, its executive vice
president for marketing.
“We’re deliberately voting with our pocketbooks,” he said.
In a nationwide telephone survey
of 1,000 adults in March, more than 60 percent told the Consumer
Reports National Research Center that they would be willing to pay at
least 5 cents a pound more for meat raised without antibiotics.
“Before, it was kind of a nice little business, and while it’s still
microscopic in the grand scheme of things, we’re seeing acceptance from
retailers across the country, not just in California and on the East
Coast,” said Stephen McDonnell, founder and chief executive of Applegate, an organic and natural meats company.
Mr. McDonnell said a confluence of trends, from heightened interest in
whole and natural foods to growing concerns about medical problems like diabetes, obesity and gluten allergies, were contributing to the demand for antibiotic-free meat.
There is growing concern among health care experts and policy makers
about antibiotic resistance and the rise of “superbugs,” bacteria that
are impervious to one or more antibiotics. Those bacteria can be passed
on to consumers, who eat meat infected with them and then cannot be
treated.
In November, the Centers for Disease Control and Prevention and 25 national health organizations and advocacy groups issued a statement
on antibiotics that, among other things, called for “limiting the use
of medically important human antibiotics in food animals” and
“supporting the use of such antibiotics in animals only for those uses
that are considered necessary for assuring animal health.”
In 2011, there were several prominent recalls involving bacterial
strains that are resistant to antibiotics, including more than 60
million pounds of ground beef contaminated with salmonella Typhimurium and about 36 million pounds of ground turkey spoiled with salmonella Heidelberg.
Consumer Reports released a study
last month that found the bacteria Yersinia enterocolitica in 69
percent of 198 pork chop and ground pork samples bought at stores around
the country. Some of the bacteria were resistant to one or more
antibiotics.
Analysis of Food and Drug Administration data by the Center for Science
in the Public Interest found that 80 percent of all antibiotics sold in
the United States are used in animals. The majority of those antibiotics
are used to spur growth or prevent infections from spreading in the
crowded conditions in which most animal production takes place today.
The European Union has banned the use of antibiotics to accelerate
growth, and the European Parliament is pushing to end their use as tools
to prevent disease as well.
The oregano oil product Mr. Sechler uses, By-O-Reg Plus, is made by a Dutch company, Ropapharm International. In the late 1990s, Bayer conducted trials on the product, known as Ropadiar in Europe, comparing its ability to control diarrhea in piglets caused by E. coli with that of four of the company’s products.
In all four test groups, Ropadiar outperformed the Bayer products.
“Strange but true!” Dr. Lucio Nisoli, the Bayer product manager, wrote
in his report on the trial. “Compared to the various anti-infectives,
with Ropadiar I have obtained much more effective and quicker results.
Furthermore, piglets treated with Ropadiar look much more healthy and
were not so dehydrated and wasted.”
Astrid Köhler, a spokeswoman in Monheim, Germany, for Bayer Healthcare’s
animal health business, confirmed that the company had done the trial
but said that “in further evaluations the results of the first study
could not be replicated with the same species, nor with other species.”
Other testing is rare. A test
of oregano oil on four small farms in Maine, which was financed by a
$9,914 grant from the Agriculture Department, found it was effective in
controlling the parasites and worms that afflict goats and sheep.
Dr. Harry G. Preuss, a professor of physiology and biology at the
Georgetown University Medical Center, studied the effectiveness of
oregano oil on 18 mice infected with staph bacteria. Six mice were given
oregano oil, and half survived for the full 30 days of the treatment.
Six received carvacrol, regarded by many experts to be the antibacterial
component in oregano, in olive oil, and none of them survived longer
than 21 days. Six other mice received only olive oil and died within
three days.
The study, which was underwritten by a company, North American Herb and
Spice, and presented at a meeting of the American College of Nutrition
in 2001, was repeated and all those findings were corroborated, Dr.
Preuss said.
Dr. Preuss said he had applied to the National Institutes of Health for
financing of a larger study, with no luck so far. “This is really
promising, particularly when you consider that we are facing a crisis in
our hospitals and health systems with the increasing resistance to
antibiotics,” he said.
After hearing about Bell & Evans’s use of oregano oil, Bob Ruth, the
president of Country View Family Farms, a Pennsylvania-based company,
decided to test it on some of his pigs. Over the last six months, about
5,000 pigs have eaten feed laced with By-O-Reg after being weaned from
their mothers.
“The preliminary results are encouraging, but we need to be sure it’s
giving us the results we need to give us the confidence to start using
it more broadly,” Mr. Ruth said.
Mr. Ruth and Mr. Sechler warned that using oregano oil to control
bacterial infection also requires maintaining high standards of
sanitation in barns where animals are sheltered, as well as good
ventilation and light, and a good nutrition program.
After a chicken flock leaves a barn at Bell & Evans for slaughter,
for instance, the facility is hosed down, its water lines are cleaned
out and everything is disinfected. It sits empty for two to three weeks
to allow bacteria to die off and to ensure that the rodents that carry
salmonella and campylobacter are eliminated.
“You can’t just replace antibiotics with oregano oil and expect it to work,” Mr. Sechler said.
