BIOLOGICAL HAZARDS Biological hazard are acquired from disease causing microorganism and the poisonous toxins they may produce. Biological hazard are far the most dangerous foodborne hazard in the food service and food retail businesses. These includes harmful microorganism seen only in the microscope 1. BACTERIA 2.VIRUSES 3. PARASITES 4. MOLDS 5. YEAST Other living organism are: • Insects: RODENTS FARM ANIMAL DOMESTIC PETS BIRDS FISH PLANTS TRANSMIT DISEASE TO HUMAN BEING

The movie Contagion was a wakeup call in many aspects regarding how the possible spread of a deadly disease can play out around the world. Although the virus called MEV1 in the movie was fictional‚ the actual content behind the virus was based on events that have occurred. In fact‚ the movie’s fictional pandemic virus‚ MEV-1‚ is based on the very real Nipah virus‚ according to W. Ian Lipkin‚ an epidemiologist and virologist at Columbia University. The Nipah virus suddenly and surprisingly jumped

Unit 22 1.1 Bacteria are a single cell micro-organism that can only be seen from under a microscope. It lives off the nutrients from its surroundings. Viruses are disease producing agents far smaller than bacteria‚ They are enclosed in a protein coating which makes them more difficult to destroy. The basic unit of Fungi is a hypha which is a hollow tube. The hypha threads spread out over and into the food material making a visible mesh or mycelium. Some fungi form together to create toadstools

A ringworm is an itchy‚ contagious infection caused by a number of fungi‚ affecting the skin or scalp. One could get the infection from skin to skin contact‚ such as handshakes or hugs. One could also get it from touching a contaminated animal or object‚ such as dogs or a doorknob. The most common locations to find ringworms are the scalp‚ chest‚ hands‚ groin‚ and feet.

Coccus is a term used to describe a type of morphology that helps us distinguish different kinds of bacteria. The cell’s morphology is only one of the many ways we can differentiate the different species. Looking at these bacterium underneath the microscope is an important step to determine which kind of species it is. All cocci bacteria are not gram positive‚ but this lab will examine only this kind because of their influence in human health. Staphylococcus Aureus is a gram-positive coccus bacterium

In the 1940s antibiotics were widely introduced as a cure for common types of diseases. However‚ some of the diseases started to build up a resistance to the antibiotics and in result‚ the antibiotics became ineffective. In order to help resolve the crisis‚ antibiotics were found through screenings of soil microorganisms. However‚ soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment‚ the researchers

In this essay I am going to discuss all three of the people mentioned above but I will also show you who I believe is the most influential and why I believe this. These people changed our medical knowledge forever and will always be remembered for this. Firstly there was Edward Jenner‚ he was born in 1749 and died in 1823‚ however in his 17 years he made one of the greatest discoveries in medical history. He had heard an old wives tale about milkmaids not contracting smallpox‚ which was a deadly
