Psilocin The effects of psilocybin mushrooms come from psilocybin and psilocin.
Biology is the science of studying living beings such as bacteria, fungi, plants and animals and non-living being such as viruses. Biological contaminants of food are harmful and hazardous substances of biological origin in the food that can cause foodborne illness when they are consumed.
Biological contaminants could be microorganisms, so small that only can be seen by a microscope such as bacteria and versus, or could be large such as some parasites.
A pathogen commonly called a germ is a disease-causing microorganism. There are also some biological toxins that are associated with certain plants, mushrooms, fish and shellfish that can cause foodborne illnesses.
To prevent the outbreak of foodborne illnesses, it is crucial for food service professionals to understand all aspects of biological contaminants from how they grow and reproduce to how they contaminate food and infect humans.
Here bacteria, viruses, parasites, fungi and biological toxins will be explained and examples will be provided. Bacteria Bacteria are single-cell microorganisms that are almost everywhere, in air, water, soil, and in and on humans, animals, and plants.
They can also survive the harshest of environments from very cold to very hot. Some are beneficial to us and some make us sick or are fatal. They can be seen only by a microscope and can not be tasted or smelled They are of the greatest concern to food service professionals so all the time necessary should be spent to combat them by understanding what condition favors the growth of pathogenic bacteria and what conditions eliminate or reduce them to a safe level.
Food - Like other living beings bacteria need energy to live. Poultry ,eggs, dairy products, meat, fish, shellfish, baked potatoes and other TCS food are ideal sources of energy for their growth.
Acidity - Bacteria grow best in food that is lightly acidic to neutral. Temperature - The Temperature Danger Zone is the temperature between 41 F and F that favors the growth of bacteria.
Food service professionals must always remember this danger zone and limit the time TCS food spends in this zone. Time - In a favorable condition, such as TCS foods that stay long in temperature danger zone, a bacteria can grow to over 10 billions in 10 hours. This shows the importance of controlling the time TCS food kept in the temperature danger zone.
The more time, the more numbers and more chance of growing to a number that makes food unsafe. Oxygen - Some bacteria need oxygen for their growth aerobic and some do not anaerobic and some can grow with or without oxygen facultive. Moisture - Moisture favors the growth of bacteria.
The FDA has particularly identified three bacteria that are highly contagious and can cause severe illnesses. Food handlers diagnosed with illnesses caused by these bacteria must NEVER work in a foodservice operation while they are sick.
Eating small amount of these bacteria can make a person sick. Salmonella Typhi - Lives only in humans. Ready-to-eat food and beverages are linked with this bacteria.
Shigella spp - Found in human waste and flies, and unwashed hands can transfer it to food; - Food linked with this bacteria are food that are contaminated by hands such as salads containing TCS food potato, tuna, shrimp, macaroni, and chicken and food that has been in contact with contaminated water, such as produce.
Enterohemoregic and shiga toxin-producing Escherichia coli E. Viruses Living beings are made of cells, consume energy and reproduce.
Viruses are not made of cells, do not need energy to exist and only can reproduce using other living cells like human cells. So for them to make copy of themselves they must use living cells like human or animal cells. They can not grow and divide on food, but they can be transmitted to a human body by food or water or contaminated surfaces.
People can also transmit them to food and and to other people, in addition to food-contact surfaces. They are able to survive cooking and freezing temperatures. It can be transmitted through vomit particles. Practicing good personal hygiene by food handlers, washing, cleaning and sanitizing food-contact surfaces and a quick vomit cleanup and removal from the site are important measures for stopping the spread of viruses.
The FDA has particularly identified two highly contagious viruses that can cause severe illnesses.
The staff who have been diagnosed with these viruses must be excluded from the operation. Eating small amount of these viruses can make a person sick. Hepatitis A - The source is human feces and often is transferred by unwashed fingers to food and equipment.Mushrooms vary greatly in both size and color, and some of them, such as puffballs, don't conform to the stalk-and-cap shape.
The parent organism of mushrooms, called a mycelium, lies beneath the soil, and a single one of these can cover as much as 1, acres. Description/Taste The Portabella mushroom is one of the most imposing mushrooms in size.
It has a rounded, earthen tan flat cap with near black gills on its underside. Description. The Biology and Cultivation of Edible Mushrooms emphasizes the biological and cultivation aspects of edible mushrooms. This book refers to edible mushrooms as epigeous and hypogeous fruiting bodies of macroscopic fungi that are commercially cultivated or grown in half-culture processes or potentially implanted under controlled.
Mushrooms belong to the group of organisms called fungi, and the study of fungi, as a specialty in biology, is mycology. Like specialists in other biological disciplines, mycologists have a set of.
