Health Organization (WHO). Although the US food supply has achieved a high level of safety‚ microbiological hazards exist. Because foods may contain pathogens‚ mishandling‚ including improper cooking‚ can result in food-born illness. Irradiation has been identified as one solution that enhances food safety through the reduction of potential pathogens and has been recommended as part of a comprehensive program to enhance food safety. However‚ food irradiation does not replace proper food handling

Many are there regardless of our human presence and others are uniquely human pathogens whose access to new susceptible hosts is global diseases and the annual number of deaths they cause. Most of the diseases responsible for mortality are also leading causes of debilitation in humans of all ages. Physical hazards are natural disasters

1.1 and 1.2 Bacteria - are micro-organisms that consist of only one cell. Bacteria multiply by splitting themselves in two‚ which is called a binary fission. Because of this they can increase in number rapidly. The majority are harmless‚ but some can be pathogenic which results in bacterial infection occuring. Bacterial infections can be treated by using antibiotics. Bacteria can evolve a resistance to antibiotic e.g. MRSA. Some diseases caused by bacteria include tuberculosis‚ pneumonia‚ salmonella

One bright‚ sunny morning‚ Petunia the pathogen was visiting the amusement park/water park. But‚ before she could leave her house‚ she had to get dolled up. She put on her earrings‚ made herself purple and then she started off. Petunia started her day off by going onto the doorknob to get a ride through Louis’ body and into the amusement park. Along the way‚ Petunia met Peter the pathogen. He was very nice to her and they were going to spend the day together. Then‚ when she got into the park‚ the

A pathogenic or an infectious disease is caused by an external infectious agent or pathogen such as viruses‚ bacteria‚ parasites and fungi. These pathogens are found in water‚ soil and air and a human body can be infected from drinking‚ eating or touching something infected with germs. Examples of a bacterial pathogenic disease are pneumonia and gonorrhea‚ while viral pathogenic diseases include influenza and measles. An example of a parasitic pathogenic disease is malaria‚ while an example of

(Centers for Disease Control and Prevention) The infectious agent (pathogen) that causes salmonella is called salmonella enteriditis. The bacteria is larger than a virus; but‚ is visible to the eye with the microscope. It is rod-shaped‚ gram negative‚ non-motile bacteria that does not form spores. Interestingly enough it
