Imagine sinking your teeth into a t-bone steak that has come from a steer that was treated with hormones, or enjoying a glass of rBGH treated milk. The steak and milk may not taste any different from the same untreated products, but the hormones they contain could both, directly and indirectly, have an impact on your health. The hormones that farmers in the U.S. administer to the cattle are dangerous and have negative effects on the people and the environment. Although America admits hormone use in cattle, the fact that Europe has banned hormone use raises many questions about the possible health risks these hormones may have on consumers. America is one of the world’s largest producers of beef. According to Raloff (2002), approximately 36 million beef cattle are raised in America each year, and approximately two-thirds are treated with hormones (para.2). Farmers use these hormones to increase the rate of growth in their cattle. By increasing the cattle’s growth rate, the farmers can produce more beef and still making more money, they can sell it at an inexpensive rate to the consumers. The hormones that may be administered to beef and dairy cattle may already be produced, in small amounts, naturally in their own bodies or synthetic. According to the U.S. Department of Food and Drug Administration (2002), “the accepted naturally occurring hormones that may be administered to beef and milk producing cattle are estradiol, progesterone, testosterone, and the synthetic hormones that are accepted are zeranol, trenbolone acetate, and melengestrol acetate.” None of the hormones listed above are acceptable in the industries in Europe to give for the food and milk productions. The Food and Drug Administration (FDA) is who the American gov... ... middle of paper ... ...y cattle are responsible for the largest amount of manure production amongst farm animals (see Table 1) (para. ). In a study conducted by Louis J. Guillette Jr. of the University of Florida and Ana M. Soto of Tufts University School of Medicine in Boston, hormonal activity of water from sites located both upstream and downstream of feedlots in Nebraska were tested by adding the water samples to cells that “react in various ways to hormonal steroids” (Raloff, 2002, para 17-18). The study (as cited in Raloff) found that: Concentrations of estrogenic pollutants at two of the downstream sites were sometimes almost double those at the upstream site. And water from all three downstream sites was significantly more androgenic than the samples collected upstream. One downstream sample exhibited nearly four times the androgenicity of the upstream water (para. 19).
The most pressing issue that is associated with CAFO’s comes from the amount of manure/waste they produce. The manure that results from CAFO’s contains a panoply of potential contaminants. The manure is filled with plant nutrients such as nitrogen and phosphorus, pathogens such as E.coli, growth hormones, antibiotics, chemicals used as additives to the manure or to clean equipment, animal blood, silage...
Although using synthetic steroids is not a new concept, finding whether the drugs negatively affect humans is still being decided upon by scientists. According to Cornell University, diethylstilbestrol, or DES for short, was one of the first synthetic estrogens to be injected into the cattle and was introduced in the 1930s. Cornell University reveals, “In the year 1956, about two-thirds of the nation’s beef cattle had the DES injection prior to ent...
Today farmers use six anabolic steroids in various combinations. “Those anabolic steroids are osetradiol, progesterone, testosterone, zeranol, trenbolone, and melengestrol.” (Communication Foundation) There are three natural steroids that are used as well. The natural steroids are estradiol, testosterone, and progesterone. Also used are three synthetic hormones which include estrogen compound zeranol, andgrogen trenbolone acetate, and progestin melengestrol acetate. (Organic Consumer Association) However, when hormones are given to cattle some of the naturally occurring hormone levels could go up seven to twenty times the normal level. Scientists have growing concerns about the use of the hormones.

...eats contact. Finally, families who eat spinal or nervous tissue of cows can greatly reduce their risks of developing mad cow disease by not purchasing such items. The beef industry is willingly under surveillance, making all attempts to produce safe and healthy products. American residents should be assured that all necessary precautions have been taken to keep Mad Cow Disease out of the United States and consumer-friendly beef on market shelves. An excerpt from the FDA Consumer Magazine leaves the nation with this very “important message from both the Harvard and GAO studies. . . We must continue to work hard to make a good system even better. The FDA and the states will continue their aggressive inspection program and will continue to work closely with all components of the cattle and feed communities to help make a, thankfully, low public risk even lower.”
The endocrine system of animals is a main source of bioregulatory compounds. Hormonal actions regulate all aspects of animal life: reproduction and development, digestion, metabolism, behavioural responses etc. (Hertenstein 2006, Norris 2007). Hormones and glands of vertebrate and invertebrate endocrine system differ in structure and function, but their main regulatory role remains conserved. However, the balance among the environmental clues, hormonal signals and organisms’ responses can be easily disturbed. One of the causes of this disturbance is the presence of Endocrine Disrupting Chemicals (EDC’s) in the environment.
A lot of beef on the market today is from a GMO. The GMO is the Super Cow (Belgian Blue). These cows are made by farmers messing with a gene. The cows have double the muscle mass but live a painful life. When the cow die since they are so big they have a lot of hazards waste. This began in the 1800s when farmers started experimenting with cows and made them. When cattle breeders look for cattle they get the biggest ones and breed them in hope they would be bigger. Since people have been messing with genes some get a defect in which there muscles don't stop growing and this can be painful to the cow. The farmers purposely mess with the genes. The gene they interfere with is the myostatin. This gene is responsible for telling the body to stop growing muscle. The cows go through a lot of pain when there muscles don't stop growing. The purpose to all this super cow stuff is to create more meat. This way of getting more meat is growing in the U.S.. This has been a process has gone on for about a century.They have picked certain cows to breed so there offspring with have more meat and the farmer will make more money.
Cattle have been a part of the American history since the first settlers established colonies from the eastern hemisphere. Today, there are countless breeds of cattle which have been developed throughout the centuries. Charolais, Limousin, and Angus cattle are a few of the breeds known for their beef production in America. Holstein and Jersey cows make up the majority of dairy production. It is common to find many small family farms across the country with at least one dairy cow to supply their daily milk and other products. The hide of cattle can also be tanned, and used for leather products such as clothes, sporting equipment, and a variety of thi...
This review focuses on minimizing losses associated with bovine dystocia. Annual financial losses sustained by the United States’ beef and dairy industries are substantial. Studies have shown that thirty-three percent of all of calf death losses in the United States are due to dystocia. Many producers have responded by implementing management practices which have led to a decline in overall occurrences. Current information suggests that additional dystocial births could be circumvented by identifying and removing genetically prone individuals from the herd’s breeding program. Implementation of tests such as genome wide association studies and comparative hormone concentration tests may prove to be useful in this identification process. Despite
In April 2008 the In Vitro Consortium first met at the Norwegian Food Research Institute. The consortium is “an international alliance of environmentally concerned scientists striving to facilitate the establishment of a large scale process industry for the production of muscle tissue for human consumption through concerted R&D efforts and attraction of funding fuels to these efforts.”Meat in both its production and its consumption has a number of destructive effects on not only the environment and humans but also live stock. Some of these effects are antibiotic resistant bacteria due to the overuse of antibiotics in livestock, meat-borne pathogens (e. coli), and diseases associated with diets rich in animal fats (diabetes). Meat consumption all over the world is increasing making meat a global issue. As a result many researchers have been trying to create meat substitutes to minimize the impact of consumption. Substitutes, to date, have been made from soybeans, peas, or even from animal tissues grown in a culture.
Dairy: GMOs used in dairy products contain growth hormones approx. one-fifth of all dairy cows in the US are modified with hormones.
The United States felt that banning hormone treated beef was unfair, since there was no scientific proof that it was a danger to a person’s health. So the US went to the WTO to eliminate this ban on an export that the US values. So the World Trade Organization imposed a committee to test whether the beef was harmful or not to the consumers, which they found no solid evidence that the beef caused any harm (Seidman 2000). Therefore WTO ruled in favor of the US that Europe’s ban was unfair international trade policy. Europe than appealed the WTO decision. Then a study released by the European Union on May 1st, 1999 stated that the six growth hormones in the US cattle pose health threats of differing severity, putting children at the highest risk. According to the European Union the worst hormone, is oestradiol-17B, a natural hormone, but some of the lesser dangerous hormones consist of testosterone, progesterone, zeranol, trenbolone, and meglangestrol acetate. (Birchard 1999) So Europe states that by imposing this ban they were actually trying to protect their country by imposing food safety standards.
Many critics say that agribusiness can have a negative effect on the population. There are speculations that the hormones injected into cows, chickens, and pigs can be harmful to us. Some people in the
Consuming foods that have been genetically altered have serious health risks based on research done on rats by The American Academy of Environmental Medicine (AAEM), an international organization of physicians. Risks include infertility, immune system problems, accelerated aging, disruption of insulin and cholesterol regulation, gastrointestinal problems and organ damage. Many AAEM physicians have prescribed non-GMO diets for all patients to improve health conditions. Jeffrey M. Smith, an advocate for non-GMO, says scientific research shows the link of GM food to thousands of sick, sterile, and dead livestock; thousands of toxic and allergic reactions in humans; and damage t...
