How can Animals kill us? There are many diseases people catch from animals and insects known as Zoonose. Whether they are food, pet or just naturally flying. People are getting sick off of animals directly, indirectly or from the environment. For centuries people always had a close relationship with animals. Whether they are house pet, farm animals or food on a plate. People and animals go hand and hand. Animals and insects are important to nature just as humans. For many years people have discovered that animals contribute to our health, many people considered animals as a healthy way to live, but what about the dangerous and deadly diseases they carry? How can we avoid getting sick from animals? We all come into close contact we animals …show more content…
They produce many things that a portion of us need and use every day. There are also several dairy products such as cheese, yogurt, and ice cream. Products that come from cows are essential to our society and can play an important part of healthy living. Also many of us enjoy eating cows from steak, cow’s foot and etc. Cows are mainly raised on a farm unfortunately if they are not taking care of properly they can also make us sick. Mad cow’s disease is a contagious, slowly progressive, degenerative, and fatal disease affecting the central nervous system of adult cattle’s. The U.S. Department of Agriculture (USDA) has tested hundreds of thousands of cattle for this disease. People catch mad cow disease by eating the meat of an affected cow this disease found in humans is called variant Creutzfeldt-Jakob disease (vCJD). The symptoms found in humans are Dementia that rapidly worsens over a few weeks or months, blurred vision, changes walking Confusion, disorientation, Hallucinations, Lack of coordination, Muscle stiffness, Muscle twitching, myoclonic jerks or seizures, nervous, jumpy feelings, personality changes, sleepiness, speech impairment and it’s not curable.

Mad Cow Disease, scientifically referred to as (BSE) Bovine Spongiform Encephalopathy, is a disease that affects those humans who eat the meat from infected cows. Mad Cow Disease is one of several fatal brain diseases called (TSE) Transmissible Spongiform Encephalopathy. (USDA) There was evidence of a new illness resembling the sheep disease scrapie. It was technically named BSE but quickly acquired the mad cow tag because of the way infected cattle behave. (CNN) In 1997, there was an award given to Stanley Prusiner, for concluding that a distorted protein called a prion was responsible for Mad Cow Disease, noted the long incubation period made it difficult to distinguish (Bryant). Another name for Mad Cow Disease is the new variant Cruetzfeldt-Jakob Disease (vCJD), similar to the Creutzfeldt-Jakob Disease, which is a deadly brain illness that strikes about one per million per year (USDA) due to genetic or unknown causes while the vCJD is contracted from eating infected cows (USDA). Both CJD and vCJD are so similarly named because of the similar effects from the illness.
Chronic Wasting Disease (CWD) is a fatal neuro-degenerative, transmissible spongiform encephalopathy (TSE) of the family Cervidae (Hamir, et.al., 2006). The family Cervidae includes mule deer, Odocolileus hemionus, white-tailed deer, Odocolileus virginianus, Rocky Mountain elk, Cervus elaphus nelsoni, and moose, Alces alces shirasi, among others (Sigurdon & Aguzzi, 2007). CWD is a prion disease, meaning it is a protein caused infection, that occurs naturally in the deer family (Song & Lawson, 2009). This protein is suspected to be an abnormal isoform (PrPSc) of the naturally occurring host prion protein (PrPC) (Blanchong, et. Al., 2009). Bovine spongiform encephalopathy (BSE), mad cow disease, is a similar prion effecting cattle as CWD affects Cervidae. Although, scientists are not sure of transmission route it is suspected that CWD is transmissible and infectious through direct contact with infected individuals or through environmental contamination (Song & Lawson, 2009). Tests have been performed showing susceptibility of altered mice to oral transmission, mimicking the suspected route of entry, and the incubation appears slower but lasts longer with oral infection (Trifilo, et.al., 2007). The approximate time from the initial infection to death is three years.
In cows with mad-cow disease, the area that is most targeted is the brain. The prions enter the brain and start deteriorating the brain. This is also why the disease is referred to scientifically as spongiform, because it causes the brain to look like a sponge with holes and empty caverns throughout the brain of the infected animal.
Exotic animals carry diseases and infections that can be potentially harmful or fatal to humans, jeopardizing the safety of the community. These diseases range in severity from common ringworm infections from African pygmy hedgehogs to lyssaviruses in p...
Bovine Spongiform Encephalopathy or Mad Cow Disease (BSE), degenerative brain disorder of cattle. Symptoms in cows include loss of coordination and a typical staggering gait. Affected animals also show signs of senility, for example, lack of interest in their surroundings, the abandonment of routine habits, disinterest in feed and water, or unpredictable behavior. Affected cattle show symptoms when they are three to ten years old.
If you had to choose between having Mad Cow Disease or becoming the top scientist in your field, which would you choose? The answer is obvious. Most realize that Mad Cow Disease, i.e. Bovine spongiform encephalopathy, is a fatal disease that has been present among cattle populations in Europe over the past couple decades. In BSE, brain cells begin to die, forming sponge-like holes in the cow’s brain tissue. Evidence shows that consumption of infected cattle could correspond with the contraction of Creutzfeldt-Jakob Disease (CJD), a similar disease in humans. Although few people have been diagnosed with CJD worldwide, they remain fearful of showing symptoms of CJD; commonly resulting in death within a year. For this reason, many Americans panicked when becoming aware that the first case of BSE was discovered in the United States in December of 2003. Unfortunately, the media is quick to show infected cows, distempered and shaking in their stalls, without giving sufficient information of the disease’s origin or the preventative measures being taken to halt its spreading. Before consumers restrict beef intake from their diets they should consider their risks. In America, chances of developing BSE is far slimmer than becoming infected with other food-borne illnesses. Although many Americans were recently startled by a reported case of Mad Cow Disease in the United States, they are assured protection from infection by: consumption of selected meats, closely guarded packaging plants, and regulation in beef imports.
Why do we have to use animals for research? Many humans and animals get the same illnesses because animals are biologically similar to humans. Animals have a shorter life cycle than humans and as a result, they can be studied throughout their whole life span or across several generations. According to information from the Office of Technology Assessment, it is estimated that between 17 and 23 million animals are used in research each year. Approximately 95% of these animals are rats and mice specifically bred for research and 4.25% of these animals include rabbits, guinea pigs, sheep, fish, frogs, insects, and other species. Most importantly, only 0.75% of the animals in research are cats, dogs, and primates. Major medical advances have been made because of the research of these animals. (Animal Research 2013)
One story tells of the time when animals, fishes, insects, plants and humans lived with each other in peace and friendship (see Mooney, pp. 250-252). Eventually, however, humans began to crowd and crush their animal partners out of carelessness and contempt. Even worse, they invented weapons of mass destruction such as the blowgun and the spear that allowed them to kill animals indiscriminately. Each animal nation then called a council and decided to invent diseases inflicting pain and death upon their human victimizers. Under the able leader...
BSE has been seen to progress very slowly in relation to other diseases, however is very contagious and fatal for not only cattle, but humans as well. While many diseases that are transmittable from animals to humans will affect the young or older humans, the median age of those infected with Mad Cow Disease is 26 (2). BSE has been linked to a fatal brain disease in humans referred to as variant Creutzfeldt-Jakob disease or vCJD. Eating meat from an infected cow is what many presume to be the cause of vCJD in humans (3). Symptoms include movement deficits, memory disturbances and cognitive impairments, all of which lead to an eventual death. The majority of the BSE cases reported have primarily been outside of the United States; from 2003 to 2012 23 cases were identified in North America, 4 of which in the United States (1). This may seem to be a small amount, however because it is believed to be transmitted through the meat of cattle it can be extremely dangerous and be shipped all over the United States before it is ever identified.

However, health concerned organizations want to ban the use of these products due to the increasing fears that they can cause harm to the consumers. For over 50 years, antibiotics have been added to the food of animals such as poultry, cattle and pigs. The main purpose for doing so is to lower the risk of disease in animals. Farm animals are housed together in overcrowded areas, which are very dirty. The hygiene level can get to such a poor state that they are often in contact with their own excreta as well as excreta of the other animals they are housed with and because of tight single air space they share, the likelihood of catching diseases from one another is further increased and very often a whole heard can be infected at one time.
Wear gloves and proper cloths if handling the infected animals to prevent the direct contact.
There are thing that make people more susceptible to contracting zoonotic diseases. Either it’s knowingly or unknowingly, humans are prone to the dangers of being direct targets of zoonotic diseases. Zoonotic diseases are transmittable in various ways weather through ingestion or direct contact. There are countless numbers of zoonotic diseases some more commonly known than others but all equally important. Preventing the contraction or spread of zoonotic diseases is easily manageable with medication and vaccines along with following small tips that not only protect humans but the animal population as well.
Cows go through a cycle of impregnation, birth and milking. 9.3 million cows are used to produce milk while they're impregnated. "Cows spend their lives indoors, typically on hard, abrasive concrete floors, frequently connected to a milking apparatus" (Farm Sanctuary). Cows are slaughtered for beef in the United States. These cows used for human consumption live for an average of 5 years because they are exhausted after all the intense torturing. "Young calves endure a long and stressful journey to a feedlot, where they are fattened on an unnatural diet until they reach "market weight" and are sent to slaughter" (Farm Sanctuary). Animal abuse in the food industry has allowed the companies to get more money because of the food they
Also, zoo life does not prepare animals for the challenges of life in the wild. For example, two rare lynxes released into the wild in Colorado died from starvation even though the area was full of hares, which are a lynx’s natural prey. The zoo is an unnatural environment that exposes animals to numerous dangers. Diseases often spread between species that would never live together naturally. For example, many Asian elephants have died in US zoos after catching herpes from African elephants.
