Got chicken? Americans can't seem to get enough of this bird. Last year each of us ate, on average, just about 80 pounds of chicken, a whopping increase over the 49 pounds we each devoured in 1980 and an eight-pound increase from 1995. Part of this food's popularity comes from its lean image as a healthier, less fatty alternative to red meat (don't forget to take the fatty skin off). Chicken's also a cheap protein source: At many popular supermarkets you'll find weekly specials at about a dollar a pound.
But at health food markets, chicken can cost upwards of $1.69 a pound. These birds may be touted as raised in an organic, stress-free environment and on a vegetarian diet, free of antibiotics. For many people, this poultry is a better buy.
The Alternative Chicken
Most of the supermarket chicken you pick up in grocery refrigerated cases are broilers, birds bred to mature in about eight weeks. In comparison, in the '60s, chickens needed 14 weeks to become adult poultry. Conventionally-raised broilers eat grain mixed with whatever's cheapest on the market, such as recycled cooking oil that's been used to fry fast foods and animal parts.
These birds reside in chicken coops the size of football fields and don't see the light of day until transported to the slaughterhouse. On the other roost, alternatively raised chickens are brought up in a variety of ways (see box), but usually enjoy a more relaxed life and diet.
Chickens on the farm receive antibiotics for two reasons: To fight off the diseases that can run rampant through a crowded chicken coop and to encourage faster growth.
Antibiotics Stimulate Growth
Mark Cook, PhD, professor of animal science at the University of Wisconsin at Madison, explains, "Gut bacteria trigger an immune system assault, which makes chickens a little feverish, suppresses appetite and slows growth. Antibiotics stimulate growth indirectly, by keeping bacteria levels down, and preventing the immune reaction." When birds get sick, they often get dosed with even more antibiotics.
This widespread antibiotic use has come home to roost and may contribute to the growth of bacteria that, frequently exposed to chemicals, have evolved ways to keep from being killed by pharmaceuticals.
This development threatens human health. Bacterial infections that people contract, once easily cured by penicillin or other drugs, are now tougher to eradicate. For instance, campylobactor, a common bacteria found in chicken, and responsible for some food poisonings, now demonstrates signs of resistance to drugs like floroquinolones. A powerful class of antibiotics, floroquinolones used to dependably conquer this infection.
"Floroquinolones are an extremely important class of antibiotics, used to treat many types of infections such as urinary tract infection, a wide variety of gastrointestinal illnesses, pneumonia, almost everything," says Kirt Smith, DVM, PhD, epidemiologist, acute disease epidemiology section, Minnesota Department of Health.
A study by Dr. Smith, published in the New England Journal of Medicine (340, 1999: 1525-32), showed that the percent of floroquinolone-resistant campylobactor appearing in infected people in his state-Minnesota-climbed from a little over 1% in infected people during 1992 to 10.2% in 1998. He and other scientists strongly suspect that the rise is a direct consequence of the Food and Drug Administration's (FDA) decision to allow floroquinolones in poultry feed beginning in 1995.
Although it was nearly impossible for Dr. Smith to trace the precise origin of campylobactor poisoning, he believes chicken was usually the source-and not just U.S. chicken. Many of the infected people had returned from Mexico and other countries.
"Sales of floroquinolones for poultry use in Mexico has increased dramatically," notes Dr. Smith.
Many alternative chicken producers do not use any antibiotic-laced feed at all. Other farmers adjust the feed to lower gut pH, making it more acidic and lowering chances of bacteria. At the U. of Wisconsin, Dr. Cook is developing antibodies to suppress the immune response to bacteria so chickens won't need antibiotics to spur growth. Buying and dining on chicken raised with little or no antibiotics could beneficially lower your risk of contracting a hardy bacterial infection. Better to catch campylobactor from an antibiotic-free chicken than a conventional chicken, speculates Dr. Cook. "There's less likelihood the bug will be resistant, and a better chance your problem can be cured with antibiotics," he explains.
And, looking beyond your own immediate health risk, buying antibiotic-free chicken makes a small contribution to stopping the spread of antibiotic resistant bugs. A Matter of Taste Conventionally raised chickens get little exercise and live only eight weeks, so they're tender but bland.
"There's not much taste in a modern chicken. Free range or organically grown, older birds usually have more taste," notes Dr. Cook.
The days of barnyard chickens happily clucking and strutting around in picturesque nature have disappeared with the family farm. Today, chickens lead a meager existence. After hatching, baby chicks are tossed into a gigantic hen house that is home to up to 30,000 birds. Their short lives are lived within the United States Department of Agriculture (USDA) mandated 3/4 square foot per chicken. In that squeeze, birds can catch "chicken influenza," especially in winter when it's too cold to let in much fresh air.
Laying hens don't experience much more of a peaceful existence. These birds live their years with about five other hens, so crowded they can't flap their wings. Cages, suspended in the air, let eggs roll into a holding area. So they don't peck each other, hens are often debeaked, a painful process that can cause infection.
Hens go through natural laying and "dry" cycles. Growers manipulate this cycle by "forced molting," depriving hens of food for four to 14 days to keep them constantly laying. By the end of two years, hens are worn out. Their inactivity weakens their bones enough that electrical stunning, the usual method for knocking chickens out before slaughter, shatters their bones. So some wind up being plucked and boiled alive, according to Mary Finelli, program director for farm animals and public health at the Humane Society of the United States. The meat from these hens, tougher than other birds, was probably in your deli lunch sandwich. It's also used in the school lunch program or may end up in dog food.
"Generally, organically-grown broilers and hens have it better because room to move is part of the organic certification process," says Finelli. Finelli suggests visiting chicken suppliers to find out how chickens are treated. Or, she advocates a Humane Society book listing reliable firms. For a local producer call the society: 202-452-1100. According to a Consumer Report report, some growers force chickens out the last week of their lives to brand them "free range." So free range isn't a prime standard for choosing a decently raised chicken. However, turkeys thrive outdoors, so choosing free-range turkey is often a good idea for better tasting poultry.
In any case, organic is your best bet for chicken without pesticides. Make it your main choice for your 80 pound yearly consumption!
To fight cruel treatment of poultry:
• Forced Molting Ban. Forced molting is shocking hens for more eggs. To support petitions banning forced molting write: Docket Manage-ment Branch, FDA, Dept. Health & Human Serv-ices, 12420 Parklawn Drive, Room 1-23, Rock-ville, MD 20857. Include docket # 98P-0203/CP
• Downed Animal Protection Bill (House Bill 443, Senate Bill S515) spares some animals from the tortuous journey from chicken house to slaughterhouse. Mandates humane euthanization.
