Swine Meat and Diseases Many swine disease outbreaks occur every year and are most often related to a large number of pigs raised in the same area or facility continuously. Raising and producing a numerous amount of pigs can result in overcrowding which can then result in pigs who are disease carriers. These disease carriers can continue to infect and re-infect a swine producer’s herd. Without knowing or realizing that the hogs are infected the diseases can travel from swine farm to swine farm introducing new diseases into their swine herds which can produce more carriers. African Swine Fever: One of the most destructive diseases in swine known worldwide is the African Swine Fever, or ASF. ASF is a viral disease which affects both wild pigs and domestic pigs. The disease is often contracted when pigs consume uncooked food scraps and contaminated garbage or water. There are many symptoms of African Swine Fever, some of which include reddening of the ears and snout, bloody diarrhea, high fever, skin blotching and abortion frequently occurs in pregnant sows. Fatality is a very common outcome from contracting ASF. If death does not occur, the surviving pigs can carry the virus for months on end. There is absolutely no treatment or vaccine that exists for a cure of this disease. The main prevention method for the African Swine Fever virus is to be sure that all garbage fed to pigs is thoroughly cooked. ASF is a disease that can be very contagious if it is not controlled. Those pigs that become infected should be eradicated by slaughter and disposing of the carcass by burning or burial. One positive aspect of African Swine Fever is that humans have yet to transmit it.

This virus is similar to Ebola, because it started in the same place. Lab workers in Germany, in 1967, contracted the new virus while working with African Green Monkeys, which had the virus. The virus is described as a hemorrhagic fever. It has a fatality rate up to 90% and spreads through human to human contact. The first symptoms can be as simple as a fever and a headache, then can progress to organ failure, and fatal internal bleeding.
...h apparently did not prevent transmission of T. equigenitalis (Erdman et al., 2011). With the exception of one, all other stallions were infected with T. equigenitalis indirectly via handling or contaminated fomites at breeding or collection facilities (Erdman et al., 2011). According to Erdman et al. (2011), this outbreak saw the largest number of horses that tested positive for the disease since the first outbreak in 1978. The source of the outbreak was most likely determined to be a stallion imported from Denmark in 2000 that had not been detected positive for T. equigenitalis neither upon pre-import testing in the country of origin nor quarantine testing in the United States (Erdman et al., 2011). The importation of this stallion in the United States subsequently led to subsequent transmission of infection between the years 2004 and 2009 (Erdman et al., 2011).

A major issue and focus of our research deals with the diseases feral hogs transmit. Feral hogs are plagued with a host of diseases that can affect wildlife, livestock, commercial swine operations, and humans. Two notable diseases we will test for in the northeast region of Louisiana include Brucellosis caused by the facultative anaerobic bacteria Brucella
...animal feed. These high risk substances come from the brains and spinal cords of cattle that are at least 30 months of age or older. Since the feed ban in 1988 the amount of reported cases has significantly dropped. In 1998, it came down to 1,567 reported cases. Last year, 4,454 new cases had been reported, compared to 37,301 new cases at the peak of the BSE disease in 1992. BSE can eventually be eradicated if there is no other significant source of infection (6).
Mad cow disease, also knows as BSE (Bovine Spongiform Encephalopathy) is an transferable disease which slowly attacks the brain and nervous system of cattle. There isn’t any cure for the disease. The first case of BSE in Canada was a cow that had been imported from the United Kingdom in 1987 at the age of six months. The animal was destroyed upon the discovery of the disease and the Canadian government banned imports from the United Kingdom. This report relates to unit 4 in terms of the economic and industrial overview of the disease in Canada. This report is on the second discovery of mad cow disease in Canada and how it affected Canada economy and Alberta’s beef industry.
The widespread infection of cattle in the United Kingdom with Mad Cow disease caused panic worldwide and resulted in major changes to the cattle industry. Mad Cow disease caused millions of cattle to be slaughtered to prevent the disease from becoming a worldwide epidemic. Laws were implemented to regulate what is fed to the cattle and what parts of cattle can be used in animal and human food to help prevent the spread of the disease among cattle and from cattle to humans. The whole world has to be vigilant in monitoring and controlling Mad Cow disease outbreaks in order to prevent another worldwide epidemic.
However, scientist have begun to find that farm animals such as chickens have bacteria in their food that has resisted even the strongest antibiotics. This is extremely worrying because animals such as chickens, cows and pigs are consumed by people. Which means that if the animals is infected, the infection can pass to the human population. For now these bacterias are harmless but the problem still remains; what would happen if out animal food supply is infected and we are unable to cure it?
The human population has a high susceptibility to the contraction of new diseases and outbreaks of these diseases are of high risk. Diseases in recent times that have broken out into the human population are the H7N9 flu strain and SARS. Despite the risk, outbreaks like H7N9 and SARS have been controlled due to epidemiology and other disease control methods. Outbreaks of disease are not uncommon to the human population as they move to new areas around the world with foreign diseases that the native residents would have developed a resistance to.
Wear gloves and proper cloths if handling the infected animals to prevent the direct contact.
There has recently been a growing interest in outdoor pig production due to potential niche markets that include nature, free range, antibiotic-free, and sustainable products from pigs. Outdoor pig production can have benefits such as having a cost that is 40-70% lower to conventional indoor systems and can achieve similar grow margins with less capital investment, but it can also have its downfalls (Gentry & McGlone, 2003). Sows used to be housed in groups with outdoor access. In United States in 2001, 64% of the gestated sows were moved inside confinement building and given an individual stall (Peter J. Lammers, 2008). Consumers are concerned about sows being housed in gestation stalls and pigs being finished in confinement because they do not think that pigs are able to live their natural lives. This paper is written to show the pros and cons of indoor and outdoor housing for gestation and finishing pigs.
The purpose of this paper is to focus on a subject within my educational field that I can research and inform the public about. I plan to become a veterinarian .which would require my daily contact with humans and animals. Zoonotic diseases are risk factors that I have to be aware of in order to protect myself as well as my patients and their owners. Luckily developments in medicine have made it possible to cure zoonotic diseases and even prevent them from ever being contracted.
The swine influenza or swine flu is a respiratory disease in pigs that is caused by the type A influenza viruses. These viruses are referred to as swine flu viruses but scientifically the main virus is called the swine triple reassortant (tr) H1N1 influenza virus. When the viruses infect humans they are called variant viruses. This infection has been caused in humans mainly by the H1N1v virus in the United States. The H1N1 virus originates in animals due to improper conditions and the food they ingest. The virus stays in latency form, thus harmless to the respective animal. The longer the animals survive the more likely the virus is to develop and strengthen making it immune to vaccines. The virus reproduced through the lytic cycle. The virus injects its own nucleic acids into a host cell and then they form a circle in the center of the cell. Rather than copying its own nucleic acids, the cell will copy the viral acids. The copies of viral acids then organize themselves as viruses inside of the cell. The membrane will eventually split leaving the viruses free to infect other cells.
