Why Do So Many Eggs Come From Iowa?

Why Do So Many Eggs Come From Iowa?

An outbreak of bird flu has forced American farmers to kill millions of egg-laying chickens, 32 million in Iowa alone — hence the rise in egg prices.

But why so many? Because our eggs are now produced by a handful of gigantic farms. When one of their birds gets sick, the farmers have to kill them all.

This concentration of egg production wasn’t always the case. In the 1970s, there were about 10,000 commercial egg companies, according to The Wall Street Journal. Today there are fewer than 200.

Bird flu aside, depending on a few farms, mainly in the Midwest, for most of our eggs doesn’t make much sense. Eggs can be laid anywhere in the country. That includes backyards in Denver, New York, and Des Moines.

So many urbanites have taken up chicken husbandry that cities are setting down strict rules for the activity. Poultry farming in dense neighborhoods is problematic. More on that later.

But every city has farms nearby that could supply eggs. The reason a few industrial farms dominate the business is that bigger is cheaper.

“Our customer base is demanding the lowest cost possible, and that causes us to put 6 million chickens on one farm,” an executive at Rose Acre Farms told the Journal.

Some consumers care greatly about where their eggs, as well as apples, come from. The more local the better.

But fast-food chains and warehouse stores gravitate to the lowest prices. The restaurants don’t necessarily buy eggs as most of us know them. McDonald’s uses eggs in liquid form for many of its dishes (though the Egg McMuffin, the McDonald’s website clearly states, is made with “a freshly cracked, Grade A egg”).

Interesting that the concept of “food miles” — the distance American produce travels before reaching the table — was pioneered at Iowa State University’s Leopold Center for Sustainable Agriculture. Researchers there found that California onions sold in Des Moines typically journey over 1,700 miles. Produce trucked from outside the state uses between 4 and 17 times more fuel than that grown locally.

And Iowa hardly lacks for farmland.

As drought strikes California’s agricultural kingdom, concerns are rising about its ability to “feed the nation.” Meanwhile, more Americans are wondering why all their carrots must come from there. The water crisis enhances their arguments for local agriculture.

About backyard chicken farming: This is not a job for squeamish city people. Chickens smell, and their coops must be cleaned. Hens reach a point when they can no longer lay eggs. Are urban farmers emotionally equipped to turn a “pet” into Sunday dinner — or to provide retirement facilities for a hen past her prime?

Also, sooner or later, something gruesome is going to happen to one of the chickens. A dog may get at it. Or the chicken comes down ill.

Neighbors may object to the clucking and the odors. They have a point.

The desire to connect more closely with our food sources is a good one. But the idea of raising chickens in small backyards is more romantic than the reality.

In densely packed areas, growing silent lettuce, tomatoes and string beans may be more neighborly than raising living, squawking farm animals. Better to patronize your local egg producer. That would both bring fresher eggs and help boost your local farmer.

Meanwhile, there’s no point in stressing over buying food products from elsewhere in the country, especially those needing special climates (avocados) or wide-open spaces (beef). Without our food distribution system, produce sections up north would be pretty dull in February.

Moderation in all obsessions is the way to go.

Bird Flu Found In Iowa; Up To 5.3 million Chickens To Be Destroyed

Bird Flu Found In Iowa; Up To 5.3 million Chickens To Be Destroyed

By Ryan Parker, Los Angeles Times (TNS)

H5N2 avian influenza, or bird flu, has reared its head at a commercial egg-laying facility in northwest Iowa that houses as many as 5.3 million chickens, according to state officials.

All the birds in the Osceola County facility will be euthanized, according to a statement by the Iowa Department of Agriculture and Land Stewardship. The exact number of birds at the facility is unclear, department spokesman Dustin Vande Hoef said, “but it can house as many as 5.3 million.”

State officials said they had quarantined the premises. The birds will be destroyed over the next week, Vande Hoef said.

The bird flu came to light when the mortality rate for the facility’s chickens began to rise and the facility decided to run tests, Vande Hoef said. He did not identify the facility’s operator.

The facility houses nearly 10 percent of the state’s egg-laying chickens when at capacity, officials said.

There have been no reports of people being infected, according to the state’s agriculture department. And officials said they believed the risk to people from the infections in wild birds, backyard flocks, and commercial poultry “to be low.”

It is the second outbreak of bird flu reported in Iowa this month.

Last week, avian influenza was discovered in a flock of 27,000 turkeys in Buena Vista County, the Des Moines Register reported. Those birds have been euthanized, it said.

On Monday, Hormel Foods Corp. said it expected to sell fewer turkeys this year because of bird flu outbreaks in multiple states, including Minnesota, where Hormel is based.

“We are experiencing significant challenges in our turkey supply chain due to the recent HPAI outbreaks in Minnesota and Wisconsin,” Jeffrey M. Ettinger, the company’s president and chief executive, said in a statement.

However, Hormel said it expected the bird flu outbreak occurrences to decline “as the weather improves.”

The Centers for Disease Control and Prevention could not be reached for more information.

Ebola Virus Vaccine Developed By Bird Flu Scientist

Ebola Virus Vaccine Developed By Bird Flu Scientist

By Karen Herzog, Milwaukee Journal Sentinel (TNS)

Another vaccine has joined the race against the often fatal Ebola virus, and this one was developed by a group led by a University of Wisconsin-Madison scientist internationally known for his bird flu research.

The whole virus vaccine that Yoshihiro Kawaoka and his colleagues developed was constructed using a novel experimental platform, and it has been shown to effectively protect monkeys exposed to the Ebola virus at a top biosafety-level National Institutes of Health laboratory in Montana, according to an article published Thursday in the prominent journal Science.

This vaccine differs from other Ebola vaccines in development because, as an inactivated whole virus vaccine, it can prime the host immune system with the complete range of Ebola viral proteins and genes, which makes it more likely to trigger a robust immune response, according to a news release from UW-Madison.

“In terms of efficacy, this affords excellent protection,” said Kawaoka, a professor of pathobiological sciences in the UW-Madison School of Veterinary Medicine who has been working on the Ebola vaccine for years, and also holds a faculty appointment at the University of Tokyo.

There are no proven treatments for Ebola or vaccines to prevent individuals from becoming infected. Ebola, previously known as Ebola hemorrhagic fever, is a rare and deadly disease first discovered in 1976 near the Ebola River in what is now the Democratic Republic of the Congo.

Ebola has claimed more than 10,000 lives in a current outbreak in Guinea, Liberia, and Sierra Leone. Symptoms include fever, severe headache, muscle pain, fatigue, diarrhea, vomiting, stomach pain, and unexplained bleeding or bruising.

Whole virus vaccines have long been used to successfully prevent such serious diseases as polio, hepatitis, and human papillomavirus-mediated cervical cancer.

The vaccine developed by Kawaoka’s group does not yet have the backing of a manufacturer, and has not been tested in people. Human trials are expensive and complex, costing millions of dollars.

Four other Ebola vaccines in development recently advanced to the clinical trial stage in humans.

An efficacy trial for an Ebola vaccine developed by the Public Health Agency of Canada launched Wednesday in a community in Guinea where Ebola spread. About 10,000 people are expected to receive that vaccine, which reportedly has shown positive results in smaller safety trials and is backed by NewLink Genetics and Merck.

Kawaoka said the experimental platforms on which the four other vaccines were developed have drawbacks in terms of safety and delivery.

The vaccine with UW-Madison ties was constructed on an experimental platform first devised in 2008 by Peter Halfmann, a research scientist in Kawaoka’s lab.

That experimental platform allows researchers to safely work with the virus because a key gene is deleted, according to the Science report describing the vaccine’s development. The Ebola virus uses that gene, known as VP30, to make a protein required for it to reproduce in host cells. Like most viruses, Ebola depends on host cells to grow and become infectious.

By engineering monkey kidney cells to express the deleted VP30 protein, the virus could be safely studied in the lab and be used as a basis for devising a whole virus vaccine. The vaccine also was chemically inactivated using hydrogen peroxide, the Science report noted.

Early attempts to devise an inactivated whole virus Ebola vaccine through irradiation and the preservative formalin failed to protect monkeys exposed to the Ebola virus and were abandoned, according to Kawaoka.

The Ebola vaccine study conducted by Kawaoka’s group was supported by the National Institutes of Health and Japanese Health and Labor Sciences Research Grants.
