8 Egregious Animal Abuses by the Meat Industry

This is the third post in a series about reasons to consider a vegan diet.

Top 7 Health Reasons to Bypass Animal Products

While researching our books Veggie Revolution and Going Green, Sadie and I wrangled our way into several factory farms - our home state of N.C. is full of them. North Carolina has more hogs than people, and is a major poultry state too. Why? Because land is cheap, environmental laws are lax, and NC is the least unionized state. So the meat industry is free here to exploit immigrant and minority labor and pollute our rivers. Smithfield has the world's biggest hog "processing plant," in Tar Heel, NC, where 35,000 hogs per day are slaughtered. The Cape Fear River runs right by, to receive the effluent. Most states that produce a lot of animal products exclude farm animals from animal-cruelty laws. So anything that's common practice in animal farming is legal, regardless of how abusive or cruel it is. Hundreds of inhumane practices warrant comment in a post such as this. But I chose situations I witnessed while researching our books - those that had the biggest emotional impact on me.

1. Most breeding sows in the U.S. spend their lives in "gestation crates" so small they can't turn around.
The sows have no bedding, no straw, nothing to do but lie there - for 12 years. They breathe the foulest air you can imagine - after I walked through the buildings, everything I had reeked of fresh feces, including my camera. The rooms with rows of "farrowing crates" were the saddest sight, for me. Just before piglets are born, a sow is transferred from her gestation crate to a farrowing crate, where a metal bars (see photo) immobilize her and keep her teats always available to the piglets. The piglets are removed after 3 wks, then the sow is inseminated again and moved back to the gestation crate. Under pressure from animal activists, some pork producers have pledged to phase out gestation crates by 2017. But these narrow, bare crates are still the norm. Veterinarians consider pigs as smart as dogs, and without ample places to root and explore, pigs are bored to the point of insanity. Imagine keeping a dog for 12 years in a crate so small it couldn't turn around. The public wouldn't stand for it. So why do we allow it for pigs?

2. The Tyson broiler farm I visited had 24,000 chickens crammed into each shed.
As I entered a dimly-lit broiler shed, I felt claustrophobic - the air was so thick with feather and fecal dust that I had trouble breathing; the floor was spongy with 18 months' accumulation of feces. The chickens in the shed were crowded, but would get much more crowded after 2-3 more weeks' growth. Crowding maximizes profits by maximizing the number of birds in the expensive heated space, but also by keeping the birds immobile - inactive birds gain more weight. Tyson chickens are bred to be constantly hungry and to grow unnaturally fast, gaining 6 lbs in 7-8 weeks, most in the breast muscles (the most expensive cut). Some gain so fast their legs collapse and they starve, unable to reach the automated food and water dispensers. The farmer has to do a "walk-through" every day to pull out the dead birds. When the chickens have reached the target weight for slaughter at 7-8 weeks, a crew of Tyson "catchers" come in. Hidden cameras have shown the catchers literally throwing the live chickens into the crates (up to 5 birds per hand is allowed). For a description of the slaughter and processing of the chickens, read this excerpt from the book The Way We Eat by Peter Singer and Jim Mason.

3. Breeder chickens must be kept hungry all the time, or their own weight will kill them.
We visited a Tyson breeder farm, which produces fertile eggs and chicks to populate the broiler sheds. The breeder or parent chickens are allowed to live for 63 weeks (much longer than broilers) because they have to reach sexual maturity, unlike the broilers. The shed we visited contained 11,500 hens and 1,200 roosters. The breeders, being older, are bigger than broilers (9 lb hens, 12 lb roosters). They looked to me just as tightly packed in the shed as the broilers were, but the farmer said they're not, because the roosters have to be able to move around to reach all the hens. As the hens lay fertile eggs in their roosting boxes, the eggs roll out of the shed by automation, then are transferred elsewhere to hatch into chicks. Since the breeders (as parents) must have the same genes for hunger and weight gain as the broilers, the breeders could all grow to fatal proportions with their longer life spans. To prevent this, the breeders are fed minimal diets and are always hungry, said the farmer. These chickens have also been bred to lay eggs with abnormal frequency, and around 10% of the hens drop dead from "blowout" - the physiological stress of egg overproduction with a minimal diet.

4. At the Food Lion egg factory I toured, five hens were stuffed into each 18" x 20" cage.
Cages were stacked floor to ceiling, housing 1.2 million hens at the site. These hens lay "table eggs" for human consumption. Each hen, with beak clipped to prevent fighting, spends 2 years in a cage until her body is spent. "When they're done," said the manager, "we can hardly give them away." Walking up and down the aisles, I saw the hens had bare red patches and stripped feathers from trying to dust bathe on a metal grate and trying to brood missing eggs - the eggs roll onto the conveyor belt as soon as they're laid. Many had feces on their heads and shoulders from the hens stacked above them. The hens have been engineered to lay 3 times the number of eggs as a normal rural hen. If the rate of production wanes, food is withheld for several days, which forces the hens to molt, and then egg production picks up. An occasional "forced molt" is recommended by the industry to maximize production. The sheds where hens were undergoing a forced molt were very quiet. This was the worst air of all the factory farms I visited - there was a dusting of "snow" (fecal and feather dust) on everything, including me. Under the cages was an 8' ft deep trench full of hen feces. It's emptied only when the hens are replaced, every 2 years. The buildings had outdoor fans, but none were operational.

5. "A dairy cow is a milk factory. There's not much quality of life in a dairy cow,"
said the dairyman. A family dairy cow used to produce milk for 10 to 12 years, maybe live as long as 20 years. Nowadays, in the industrial-sized dairies that can house 10,000 to 18,000 cows each, a cow is generally worn out after only 3 years - her body is pushed to its limits and just gives out. In one of these mega-dairies, a cow is impregnated roughly once a year to maximize her milk production. She may also be injected every other week with BST (bovine somatotropin) to increase milk production 10% more. The continual pregnancies and abnormal milk production place a huge strain on the cow's body. The concrete floor is hard on her feet and legs, and the weight of pregnancy makes it more so. When her milk production drops too low or she has chronic leg problems or fails to become pregnant, she's slaughtered for low-grade meat. In a typical confinement dairy, a third of the herd is culled every year. What happens to the calves that result from the continuous pregnancies? Many consumers have the impression that humans take the milk the calf doesn't want. But the calves are whisked away from mom only a few hours after birth. Female calves may be raised on formula to replace the milk cows culled from the herd. Male calves may be sold at auction, or tethered alone in wooden stalls for 16 weeks, fed low-iron diets to make their flesh pale, and then slaughtered to be sold as veal. How do cows feel about losing their calves just after birth, when their systems are flooded with mothering hormones? They look for the calf and often bellow continuously, sometimes for weeks. Said Dr. Temple Grandin, "That's one sad, unhappy, upset cow. She wants her baby....it's like grieving, mourning."

6. The unnatural corn diet fed to 90% of beef cattle makes them very sick.
Cows evolved to eat grass. But corn leads to faster weight gain, so at 6-7 months of age, 80-90% of beef cattle are transitioned to an abnormal diet of up to 85% corn. At the same time, they're trucked to large feedlots; one feedlot may have as many as 200,000 steers, grouped in pens of 900 or so. The cattle spend all their time standing or lying in a gray muck of feces and urine, with access to an always-full trough of corn and food additives, until they reach slaughter weight at 12-14 months of age. Corn causes cattle stomachs to be more acidic than they should be. The industry's "Feedlot Magazine" says all corn-fed cattle develop painful "sub-acute acidosis" at some point in the feedlot. The "Beef Cattle Handbook" (for feedlot managers) says animals with sub-acute acidosis "are plagued with diarrhea, go off their feed, pant, kick at their bellies, salivate excessively, and eat dirt." This condition often leads to very painful stomach ulcers, which when perforated, lead to liver ulcers. "Acute acidosis" is generally fatal. Feedlot management is a race between erosion of the digestive system and growth to slaughter weight. An effective feedlot manager sees to it that growth wins and the animal reaches slaughter weight before it succumbs to disease. For more details about feedlot life, see Michael Pollen's article "Power Steer." For info about what goes on in cattle slaughterhouses, read Fast Food Nation by Eric Schlosser.

7. Are fish insensitive, just because they're not mammals?
Fish are smarter than you might think. I studied the behavior of cichlid fish as a project in college, and I was astonished when I realized the school of fish that I was observing all recognized me personally.  Their tank was was in a hallway constantly full of other biology students, but when these fish saw me nearby, they all immediately came to the surface and toward me - because they knew I was the one who fed them. This was regardless of what I had in my hands. Several studies report fish intelligence, and sensitivity to pain. Dr. Culum Brown trained fish to find a hole in a net on only 5 attempts. When re-tested 11 months later, the fish remembered instantly. Dr. Lynne Sneddon showed experimentally (with bee venom and acetic acid) that rainbow trout feel pain and distress, make efforts to relieve the pain, and show relief when injected with morphine. Fish are the only vertebrate animals harvested on an industrial scale, with long-lines, gill nets, bottom trawlers, etc. Death by suffocation takes about 15 minutes; others are clubbed, pulled aboard with pickaxes, or bleed out when their gills are cut off. We treat fish as if they're vegetables, and we do it to a lot of them - humans haul in 88 million tons of fish each year just from the oceans. I haven't mentioned our decimation of fish populations - read about that here. For more about the sensitivity of fish, click here. For info about farmed fish, click here and here.

8. Foie gras - who would eat it?
Fois gras is the liver of a duck or goose that has been fattened by force-feeding it a mash of corn boiled in fat. The animal is fed far more than it would normally eat; a funnel with a long tube is used to push an excessive volume of food into the bird's esophagus 2-4 times per day. The resulting fatty liver of the bird is considered a delicacy by some, especially in France. But many investigators have reported that the birds live a miserable life: grossly overweight, immobile, with numerous damaged organs. For more info about foie gras, read here.

How food affects your brain: 10 facts we now know

 Walnuts and olive oil, two of the healthful choices for your brain. Photo by Sally Kneidel

Readers -
I just received an email from Cindy Cullen at the Culinary Arts College, asking if I'd like to post a link to their article
How Food Affects Your Brain: 10 Facts We Now Know.

Some interesting information in the post, so I'm passing it along.

I need to add a couple of things in relation to their list of foods. If you eat fish, please choose fish and seafood responsibly.  Our oceans are being emptied of fish by over-harvesting, and many species once common are on the verge of extinction. In addition, many fish species contain dangerous levels of mercury and other pollutants.

Use these guides to choose seafood wisely:
Seafood Selector from Environmental Defense Fund
Sustainable Seafood Guide from the Natural Resources Defense Council
Health Alerts Seafood Guide from EDF
Seafood Recommendations from the Monterey Bay Aquarium

Choose organic
In regard to the fruits and vegetables on the Culinary Arts College list, please choose organic. Strawberries are on the list, and 54 different pesticide residues have been found on non-organic strawberries by the USDA Pesticide Data Program (according to the Pesticide Action Network). Buying organic not only protects the future health of you and your children, it also protects ecosystems and wildlife.Pesticides sprayed on crop fields are washed into nearby streams, rivers and lakes. They're also ingested by birds and other animals feeding near croplands.

Review of the documentary "End of the Line: Where Have All the Fish Gone?"

Review by Sally Kneidel, PhD, of sallykneidel.com

My husband, an ecologist, keeps a list of people whose profession matches their name, such as peanut specialist Shelly Nutt, ornithologist Christopher Bird, editor Zachary Read. But the best is Dr. Boris Worm, a marine biologist at Canada's Dalhousie University. He's always been our favorite, because we loved the peculiar marine worms we learned about in grad school.

Abundance of marine fish has decreased 90%
So I was thrilled to finally see Dr. Worm, on screen. He is perhaps the "star" of  the new and excellent documentary "End of the Line".  Worm is much more charming than his name might suggest, but the news he delivered was bad. A dogmatic researcher, Worm analyzed Japanese fish-capture records gathered over several decades, looking for trends in numbers of marine fish.  What he found was disturbing, to say the least. Since "large scale fishing" began in 1952,  the abundance of large oceanic fish has decreased globally by 90%!  

Worm said that when he first realized the magnitude of what we've lost, "it sent shivers down my spine."

The angels would weep
What exactly is "large scale fishing"? The documentary does a wonderful job of impressing upon the viewer the magnitude and power of today's modern fishing techniques. "High-tech industrial vessels are hunting down every known edible species of fish," said narrator Ted Danson.  Too many boats with too much capacity are chasing too few fish. For example, the "long-lining industry" sets 1.4 billion hooks annually, on heavy-duty fishing line that could encircle the globe more than 550 times. The mouth of a single large trawling net could accommodate thirteen 747 jetliners. Fishing vessels, and airplanes that track schools of fish illegally, are equipped with so much technological equipment, fish have no chance of escaping.  Bottom trawlers, which drag nets across sea beds and coral reefs, cut down everything in their path including the inedible, such as sea fans, corals, and sponges. The unintentionally caught or "by-catch" include sea birds, hundreds of thousands of sea turtles, sharks, whales, and dolphins.  Seven million tons of by-catch are tossed back into the ocean each year, dead.

Said Dr. Callum Roberts of York University in the U.K., "the signs of destruction brought up on deck would make an angel weep."

The film's strengths are its personal portraits
Most of the stats and data presented in the documentary are probably available from various websites, journals and books.  But the strengths of the DVD are its emotional impact, and the persuasive presentation of the whole story in one sitting. Its emotional impressions are delivered via personal stories of passionate scientists on a quest for the truth and solutions, and indigenous fishermen in handmade boats, now unable to feed their families. Said Adama, a young Senegalese fisherman, "The sea has betrayed us. If my children grow up here today where there is no future, how will they think of me as a father?".

China falsified catch data for 14 years, concealing a global decline
Until 2002, the scientific community was under the impression that, despite all odds, the world catch was increasing each year.  So, although scientists were worried, no one was too alarmed. Turns out, China had been reporting false catch data for years. The world catch is actually decreasing every year and has been since 1988.

Mitsubishi stockpiles a disappearing species - for future profits?
Another of the compelling stories told on the DVD involves the demise of bluefin tuna, as related by Roberto Mielgo, a man dedicated to identifying the perpetrators of an impending extinction. Scientists have recommended that fishing of bluefin be limited to 10,000 tons per year to allow the species to recover from previous overfishing. A ceiling as high as 15,000 might prevent collapse of the population. But for political reasons, governments have sanctioned a catch of 29,000 tons annually. In reality, 61,000 tons were caught in  one recent year - 1/3 of the entire remaining bluefin population. Fishermen and corporations cheat because they can, and they don't get caught. In the documentary, a passionate Mielgo described the role of Mitsubishi in the decline of bluefin tuna.  He believes the company is stockpiling bluefin for the day when the species will be extinct and the price of their highly regarded flesh will skyrocket. The bluefin situation demonstrates what multinational corporations, international fishing policy, and consumer demand can do to a wild species.

"We are crazy!"
Several scientists and fisheries workers expressed pessimism about human nature and the ultimate depletion of the ocean. Said professional diver Haidar El Ali, "Man is not going to change and the sea is going to be dead.  Because man is crazy.  We are crazy!"

Steve Palumbi of Stanford University said that, assuming things remain the same, the ocean will be devoid of edible fish by the year 2048.  Added Charles Clover, the author of the book on which the documentary is based, "When we start really feeling the effects of climate change, when we start running out of food to feed ourselves, at the same time we will have squandered one of the best resources we've ever had on the planet."

What will remain? Jellyfish, plankton, and.....worms.  Lots of marine worms.

Solutions
Toward the end, the DVD turned to solutions. Farmed fish is not a solution, because more wild fish (such as anchovies) are harvested to feed the farmed stock than are produced for our consumption...a clearly illogical and unsustainable endeavor.  Five kg of anchovies are required to produce 1 kg of farmed salmon.

Future "global marine reserves" comprising 20-30% of the oceans were proposed with some enthusiasm in the DVD - large areas of ocean where commercial fishing would be banned.  Nice idea, but much of today's commercial fishing is carried out in violation of governmental or international regulations.  How would protection of these reserves be enforced?  The DVD said $12-14 billion per year could manage the reserves.  Maybe.

According to the filmmakers and Dr. Ray Hilborn of the University of Washington, Alaska is on the frontline in the battle to conserve the sea.  The number of fishing boats off the coast of Alaska is carefully monitored.  Catch limits are set at sustainable levels or below.  Fishing boats are given only a limited amount of time to fish.  While the catch rate in the North Sea is 50%, Alaska's catch rate is only 10%.

The documentary mentioned several companies that are making an effort to conserve marine fishes.  By 2011, Walmart will sell only fish approved by the Marine Stewardship Council, a board that certifies sustainable fishing.  Ninety percent of the fish served by McDonalds are MSC approved. Two-thirds of Birds Eye fish are from sustainable sources.

Recommendations for consumers
The filmmakers asserted that, among the world's problems, the overharvesting of marine fish is one of the easiest problems to fix. They recommended:
1) Ask before you buy. Eat only sustainably harvested seafood. (For a guide, see www.seafoodwatch.org). 
2) Tell politicians to cut the fishing fleet.
3) Join the campaign for protected marine reserves and responsible fishing.

I wish they had stressed...
The DVD mentioned the value of eating lower on the marine food chain - eating anchovies ourselves instead of feeding them to farmed fish. And it mentioned very briefly changing consumer habits. But the film never addressed, that I recall, the option of not eating fish at all. We don't need to eat fish, or food from any animal sources. Ecologists, MDs, nutrition scientists and many, many popular writers have asserted that humans can reduce our ecological impact and our carbon footprint, and improve our health, by avoiding animal products in our diet altogether. Why does a filmmaker on such a dire subject as complete depletion of the oceans not explore this avenue of future action?

The other topic I would like to have seen explored is the obvious suffering of the fish in many of the scenes in the DVD. Conscious animals were often hauled on board boats by stabbing and yanking them with large hooks, then clubbing them to death or tossing them down chutes to be buried by more live fish.  The camera many times showed rivers of blood on decks of ships. Fish are vertebrates, like ourselves, and have brains not that dissimilar from our own.  They feel pain; they feel fear. They don't look as much like us as other vertebrates, they're not cuddly - but they are sentient. For more details about studies demonstrating the sensibilities of fish, see Peter Singer and Jim Mason's book about animals as food, The Way We Eat.

Awareness is key....show this important film to students
The strength of the DVD, in my opinion, was not its prescription for solutions, but its touching and memorable portrayal of the scientists and activists so desperately trying to educate consumers of the world....our oceans are on track to be empty 38 years from today.  If we're not part of the solution, we're part of the problem.  Awareness is the first step toward change. And this documentary does an excellent job of dramatically increasing awareness. I strongly recommend it to teachers. Show it to your classes. Talk about it and brainstorm solutions. The next generation has a short window of opportunity to take action. Or the jellyfish, plankton, and motly assortment of marine worms my husband and I found so intriguing will be the sole inhabitants of our grandchildren's seas.

Extra material with the DVD:
The DVD comes with a wallet-sized card, "National Sustainable Seafood Guide." The card lists Best Choices, Good Alternatives, and Avoid.  It also mentions these websites as useful:

Number of imperiled fish almost doubles in 20 years

Salmon: photo courtesy of http://latimesblogs.latimes.com

Forty percent of fish species in North American streams, rivers, and lakes are now in trouble. That's according to a detailed new evaluation of their conservation status by scientists from Canada, Mexico, and the U.S. Geological Survey. The report was just published by the American Fisheries Society in the journal Fisheries.

The 700 fishes now listed as imperiled represent a whopping 92% increase over the 364 listed in the previous report 20 years ago. Of those 700 imperiled fishes, 280 were listed as endangered, 190 as threatened, and 230 as vulnerable.

Said Mark Myers, director of the USGS, "Freshwater fish have continued to decline since the late 1970s, with the primary causes being habitat loss, dwindling range, and introduction of non-native species. In addition, climate change may further affect these fish."

Unfortunately for American consumers, the fish most at risk include many that are popular with sportsmen and commercial fisheries, such as salmon and trout of the Pacific Coast and western mountain regions. More than 60% of the salmon and trout species surveyed had at least one population or subspecies in trouble. Twenty-two percent of sunfishes (a family that includes popular black bass, bluegill, and rock bass) were listed.

Areas with especially high numbers of imperiled fish include the Southeast, the mid-Pacific coast, the lower Rio Grande, and basins in Mexico that do not drain to the sea.

This is the third list compiled by the American Fisheries Society's Endangered Species Committee. Of the fish on the 1989 imperiled list, only 11% have improved in conservation status. The remaining 89% are more at risk or have stayed the same.

"Fish are not the only aquatic organisms undergoing precipitous declines," said USGS researcher Noel Burkhead, chair of the AFS Endangered Species Committee and a lead author on the report. "Freshwater crayfishes, snails and mussels are exhibiting similar or even greater levels of decline and extinction."

What about that seafood dinner you have planned??

If you plan to continue eating fish, check out the Seafood Selector on the website of the Environmental Defense Fund, at http://www.edf.org/page.cfm?tagID=1521&redirect=seafood. See their "Eco-Best", "Eco-OK" and "Eco-Worst" lists of seafood, easy to understand at a glance. The webpage has lots of other information about eating fish, including fish recipes, fish substitutions, and information about pollutants such as mercury.

Our 2008 book Going Green has a section on fish called "Seafood - Here's the Catch." In this section we describe destructive mass-fishing techniques such as blast fishing, longlines, and gill nets. Sadie reports on a couple of disturbing interviews with fisheries professionals, who report that workers pee into the fish-stick vat, drop boots into the mix, etc. We were surprised too at what we learned while researching farmed fish. Most of the fungicides, dyes, antibiotics, and pesticides dumped into the cages of farmed oceanic fish actually wind up outside the cages, where they impact wild communities. And then there are the genetically modified fish..that's another distressing story. The consumption of fish is not as simple as it once was! For a thorough review of these issues, check out The End of the Line: How Overfishing is Changing the World and What We Eat by Charles Clover, or The Empty Ocean by Richard Ellis.
