I believe that higher education is the key to success‚ I have made pursuing my college degree in Food Science my priority. Starting my academic career at Tacoma Community College while in high school was the first step towards my goal. My short term goal is to begin my studies in Food Science in Fall of 2016 at Washington State University. I plan on focusing on the dairy industry that will prepare me for many different kinds of food manufacturing and quality control. My long term goal for my degree

Beharry Due: February 24‚ 2014 According to the epidemiologic triad‚ there are three factors that influence the occurrence of disease: 1. Etiologic agent 2. Host factors 3. Environmental factors Describe each of these factors for a Salmonella foodborne outbreak. What are some of the host factors that can influence the occurrence of a disease? Salmonella Most people associate salmonella infection (salmonellosis) with raw or undercooked poultry or meat‚ but it can be found on fruits and

The first line of defense includes the skin‚ cilia‚ tears‚ stomach and mucous membranes. Because the rotavirus is contagious‚ you will most likely obtain it when you touch the doorknob which means your hand will be the first to try and prevent the pathogen from further entering your body. The skin tries to retain fluid and protect against disease. It is a mechanical barrier that can secrete

There are three categories of bioterrorism agents: A‚ B‚ and C. The criteria for A‚ high security risk pathogens‚ is that the pathogen is easily able to be transmitted person to person‚ high mortality rates‚ public panic‚ and might require special action for public health preparedness(National Institute of Allergy and Infectious Diseases‚2016). Category B is the second highest priority pathogens‚ the criteria is that it is moderately easy to spread‚ a moderate or low amount of deaths and require specific

the immune system. White blood cells are located near places where there could be pathogens entering‚ such as the tonsils. They are found in these places because they protect entry into the body. If pathogens do try to enter then the white blood cells will become activated and will attack the area of infection. They become activated when the dendritic cell engulfs neutrophils which contain the remains of pathogens that they have killed. The dendritic cells travel in lymph to the lymph nodes where

transports nutrients from blood to the cells‚ and it takes back carbon dioxide and other wastes from the cells back into the blood. Despite this difference of function‚ however‚ the lymph and interstitial fluid do interact with each other. Along with pathogens‚ lymph also takes waste from cells to be expelled from the body. Simply put‚ lymph takes away the waste the interstitial fluid is carrying. Interstitial fluid not only interacts with lymph‚ it also interacts with plasma. Plasma is a fluid like lymph

Military use of biological weapons “Biological weapons amount to no more than “weapons of mass disruption” (Introduction to Biological Weapons). Biological weapons are toxic materials taken from pathogens (bacteria)‚ host or target. These can be put in something as simple as a letter‚ in an envelope‚ or something as complex as a missile containing the materials inside. The military should not use biological weapons because the U.S. doesn’t have the funds to protect the country‚ they are
