A growing issue in the world today is the use of antibiotics and growth hormones in animal production industry. However, for over sixty years Americans have been exposed to hormones on a regular basic when they consume beef. (1) On average eighty percent of all feedlot cattle are given hormones to help them grow at an increased rate. (2) “In 1988 the European Union banned the use of all hormone growth promoters.” (1)
Today farmers use six anabolic steroids in various combinations. “Those anabolic steroids are osetradiol, progesterone, testosterone, zeranol, trenbolone, and melengestrol.” (2) 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. (1) 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.
The scientists are concerned with the hormones use and their impact of the environment. The scientists are concerned with the hormones being excreted in the manure. The scientists say, that the hormones that are going into the can be found in the soil and the water supply. The scientists also say that the hormones being used are affecting human development through the human reproductive system.
“High levels of hormones can cause problems in the human body, but can hormones we ingest really alter our hormone levels.” (3) There are studies that show mothers that consumed meat while pregnant have sons with affected sperm counts. The sperm concentration of sons born to mo...

...re that animal and be slaughter for human consumption. If the meat is test in a slaughter house and the amount of hormone in the meat is above the slaughter limited then the animal is discarding and not produced for human consumption. The protein content in the carcass of an animal that was hormone implanted is usually raised by ten percent or more.
People say that the synthetic hormones could cause many human health risks, ranging from early puberty to cancer which causes two0thirds of Americans to worry about the use of the synthetic growth hormones in cattle operations. There are also many people that are worried that the use of antibiotics for treating bacteria on farms could cause the drugs to become resistant to the bacteria, which also infect humans. It is said that hormones are used more in the beef cattle operations than in dairy cattle operations.

Hormone steroids used in food can have many effects on the people who eat them. Steroids in animals make the meat taste better and become lean. Even though the steroids they put in animals are edible, it does not mean they do not have an effect on those who partake of the food. The steroids in animals have a large amount of sex hormones. These steroids sometimes can contribute to cancer. They also may make girls develop early and cause them to hit puberty faster. It has been found that girls who eat foods with steroids have a higher chance of having breast cancer. People who eat dairy products that have steroids in them are increasing the risk of breast cancer. Those who eat meat products may have effects on children w...
Factory farming is a necessary component of our modern food production and supply system. In 2005, the U.S. produced 45.7 billion pounds of red meat. It efficiently produces and distributes huge quantities of food to feed the growing population of America. But the overfeeding of antibiotics in the U.S. meat industry has gotten to the extreme and it calls for a drastic change in order to prevent a potential public health crises.
Today people are using pesticides and hormones in many of the items that we use each day and it’s affecting our society in various ways. Pesticides are used in many different ways including: keeping insects away from plants, controlling weeds, and controlling the spread of diseases to plants. Hormones make animals grow faster and/or produce leaner meat for food. Although some people believe that pesticides and hormones should be used to help crops and livestock, they can be very harmful to others as well as the environment.
Anabolic steroids, technically known as anabolic-androgenic steroids, are drugs that are related to the cyclic steroid ring system and have similar effects to testosterone in the body. They increase protein within cells, especially in skeletal muscles. They address the development and maintenance of masculine characteristics such as the growth of the vocal cords, testicles and body hair. Anabolic steroids were first made in the 1930s, and are now used therapeutically in medicine to stimulate bone growth and appetite, induce male puberty and treat chronic wasting conditions; such as cancer and AIDS. The American College of Sports Medicine acknowledges that AAS, in the presence of adequate diet, can contribute to increases in body weight, often as lean mass increases and that the gains in muscular strength achieved through high-intensity exercise and proper diet can be additionally increased by the use of AAS in some individuals.
Although steroids have many negative effects, they have many needed medical purposes. Androgens have many legitimate medical uses, such as the use for treatment of hypogonadal men to compensate for the lack of endogenous production. Anabolic steroids are also helpful for the treatment of certain adolescent diseases, some types of anemias, and for a relatively rare form of edema. Other clinical uses focus on the tissue building and anti-catabolic effects, such as in the treatment of burn victims, AIDS, or HIV positive patients, or patients malnourished from disease or old age (Bellino 1).

In case you who are reading this does not know steroids are any numerous naturally occurring or synthetic fat soluble organic compounds having as a basis 17 carbon atom arranged in four rings and including the sterols and bile acids, adrenal and sex hormones certain natural drugs such as digits compounds and the precursors of certain vitamins.
The abuse of livestock is a widespread problem that affects everyone who buys and consumes meat products. Most people are not even aware of how slaughter-destined animals are treated while alive, what chemicals are forced into their bodies, what they are forced to eat, and how they are slaughtered. Fortunately, an increasing number of slaughter plants and small farms have been conforming to the U.S. Department of Agriculture’s (USDA) Humane Methods of Slaughter Act (HMSA), after it was passed in 1958, and amended to be fully enforced in 2002, but there are still slaughter plants that abuse, neglect, and provide poor conditions for livestock (“Humane” Animal). When looking at the realities of mass producing meat and animal products, two serious problems arise: the quality of life for the animals, and the possible negative health effects for the people who consume these products.
Too much human meat causes a buildup of vitamin A and amino acids such as homocysteine in the bloodstream, which could cause congenital defects in future offspring. However, if human organs which are rich in B vitamins and folic acid are eaten along with the human meat, homocysteine is not able to metabolize in the bloodstream. This means that cannibalism could hypothetically be the basis of a healthy diet (“Natural Food”). Contrary to human meat and organs actually being healthy to a human diet, cannibalism is also said to cause madness and addiction based on sexual urges and gratification. Kate Rix depicts that sexual cannibalism in its truest sense may in fact lead to the development of necrophilia tendencies.
Like antibiotics, hormones can be produced and placed in animal feed, for example Bovine Somatotropin, which is given to cows to increases milk production.2 The use of hormones and antibiotics in animal feed has been a controversial topic for many years. There are obvious advantages and disadvantages with the use of such products. Farmers see hormones and antibiotics as a major advantage as the increase their profits and gain the maximum out of their livestock.
An abundance of Americans have no idea that most of the food that they consume are either processed or altered in one way or another. “Almost all beef cattle entering feedlots in the United States are given hormone implants to promote faster growth. The first product used for this purpose is DES (diethylstilbestrol) it was approved for use in beef cattle in 1954. An estimated two-thirds of the nation's beef cattle were treated with DES in 1956. (Swan, Liu, Overstreet, Brazil, and Skakkebaek)” Many people enjoy the various meats that comes from a cow, but that would probably change if the consumers knew that cattle is one of the most processed meat source in the market today because of the synthetic hormones that the cows are given. “ The three synthetic hormones are the estrogen compound zeranol, the androgen trenbolone acetate, and progestin melengestrol acetate. (Swan, Liu, Overstreet, B...
Today’s medical experts say that avoiding meat helps you avoid saturated fat. They have found out from studies that women who eat meat daily have a fifty percent greater risk of developing heart disease than vegetarian women and a sixty-eight percent greater risk in men (staff writer). People may not know about serious diseases meat can cause such as, mad cow disease and foot-and-mouth disease. In the September 1999 issue of the Emerging Infectious Diseases, approximately 76 million food-borne illnesses- resulting in 325,000 hospitalizations and 5,000 deaths occur in the United States each year from improperly cooked or diseased meat (Licher). That is a lot of fun!
Meat cultivation uses more land, water and resources to house, transport, and slaughter animals and their grain and food than it would cost to fund in vitro meat studies. 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).
The health benefits of a vegetarian diet are hard to ignore. Vegetarians have a lower chance of developing many diseases, such as cancer and diabetes. Women who eat meat daily are more likely to develop breast cancer. According to an article in the Journal of the National Cancer Institute, “consumption of well-done meats and, thus, exposures to heterocyclic amines (or other compounds) formed during high-temperature cooking may play an important role in the risk of breast cancer.” Men are also more than almost more likely to develop prostate cancer than those who do not include meat in their everyday diets. “Up to 80 percent of prostate cancer is attributed to dietary practices, and international comparisons show strong positive associations with meat consumption” (Alexander, 2010). Vegetarians have also shown to have lower blood pressure, better digestion, and more energy than humans with a meat based diet. The effects of a vegetarian life style ...
