Safe food handling in a kitchen is vital for human survival, without it, we could be putting harmful substances and bacteria in our system that has the potential to make us sick. Because of this potential, ‘safe food handling’ has been put in place to help make the kitchen safer. This essay will go on to talk about bacteria as pathogenic, some of the factors that are affecting bacterial growth, with the reference to some of the experiment 's that were done to see which homemade remedies worked the best to remove bacteria, and recommendations and the importance of the experiments results to the hospitality industry.
Bacteria are an important factor when it comes to safe food handling within the kitchen, because even though some bacteria are

The pH of an environment, which is a measure of its acidity or alkalinity -- is important for bacterial growth. Most strains of bacteria prefer to grow in conditions with neutral pH, similar to the pH of the human body, therefore this is similar to the temperature as is talking about the human body because some bacteria’s rely on simular temperatures and PH to those of the human body showing their similarity. The final factor that can contribute to bacteria growth is Food/Nutrients because all bacteria whether is needs any of the other factors about all requite energy to survive, live and grow and food/nutrients require energy sources such as sugars, starch, protein, fats and other compounds to help provide the nutrients that the bacteria …show more content…
However, this strain of bacteria is able to live for relatively short periods of time outside of the body. This enables it to be detected within food and water. There are several strains of E Coli bacteria which reside within the lower intestine and perform a range of useful functions, such as protecting the body against disease and infection. In an experiment that was conducted from the 3rd of May till the 4th of May, homemade remedies were tested to see which one worked best in fighting against the bacteria of the E Coli and most likely they 0157:H7 strain. There were 5 ‘homemade remedies’ that were used to conduct this experiment and the base were water while we used bleach, vinegar, Teatree oil and Hydrochloric acid as our homemade remedies and the goal was to see which of these would work best to attack and kill the E-Coli and was on a cotton swab and on
The first day an unknown sample was assigned to each group of students. The first test applied was a gram stain to test for gram positive or gram-negative bacteria. The morphology of the two types of bacteria was viewed under the microscope and recorded. Then the sample was put on agar plates using the quadrant streak method for isolation. There were three agar plates; one was incubated at room temperature, the second at 30 degrees Celsius, and the third at 37 degrees Celsius. By placing each plate at a different temperature optimal growth temperature can be predicted for both species of bacteria.
Escherichia coli is a member of the family Enterobacteriaceae. It is a bacterium with a cell wall that has many components. Escherichia coli can live without oxygen which means that it is a facultative anaerobe. It is also capable of fermenting lactose under anaerobic conditions, and in the absence of alternative electron acceptors. There are effects and various factors that limit its growth rate. Its morphology consists of a rod-shaped gram negative bacteria that is commonly found in soil, water, vegetation, human intestines, as well as the intestines of animals. Its presence can be good or bad.
E. Coli and other foodborne illnesses are something that should be of major concern to everybody, becasue nobody is safe from it. It is not something that can be prevented or
RTE foods are under scrutiny due to the widespread outbreaks of Listeriosis over the last 2 decades. Post-processing contamination is a common pathway for L. monocytogenes to be introduced into food products because it is so widely spread in the environment (1). Once contamination occurs, L. monocytogenes can proliferate at refrigerated temperatures prior to consumer use of the food (1). RTE foods are typically not further processed after being received by consumers or retailers, which allows for Listeria monocytogenes to proliferate and infect individuals under the right circumstances.
It is a bit difficult to find a solution to a problem without knowing its causes. Therefore, it necessary that to identify the problems caused by bacteria, we need to know what actually caused it. Identifying the unknown bacteria
At Middlefield Collegiate Institute, the gym will have the most bacteria, the cafeteria will have the second most bacteria and the area near the front door will have the least bacteria. This is evident because the gym is a moist and warm environment which will make the gym a suitable place for bacteria to thrive. Likewise, the cafeteria is warm and many people visit it occasionally, thereby making it a possible location for bacteria to cultivate. However, the cafeteria will be more sanitized in order to ensure that students
Wash kitchen work surfaces and utensils with soap and water immediately after they have been in contact with raw meat or poultry. The client must understand that uncooked meat and poultry should be kept separate from produce, cooked foods and ready to eat foods. People with salmonellosis should not prepare food or pour water for others until their diarrhea has been resolved too.
There are many ways to store food safely. Let’s say you’re going on a backpacking trip and have the options of pre-cooked hamburgers, fresh strawberries, peanut butter, crackers, and raisins. What foods should you leave behind because of bacterial growth and which foods can you take? Foods with higher water activity levels are likely to last shorter because they will have microorganisms living inside. Some microorganisms are microbes and enzymes. To prevent microorganisms from living inside, foods with higher water activity levels than 0.85 aw, potentially hazardous foods, must be kept refrigerated to prevent bacteria growth, like fresh fruit of raw meat. Potentially hazardous foods are foods that can cause illness if their bacterial growth isn’t put to an end.
Bacteria usually live on and in all creatures. Not all bacteria are pathogenic (disease producing) in fact, many are harmless. Pathogenic bacteria can cause very serious infections. Before antibiotics were discovered, there were many deaths due to bacterial infections [1].
In certain foods there are good bacteria or probiotics that are needed. They help boost your immune system and also helps protect against bad bacteria. The different types of foods that contains good types of bacteria are: Yogurts which is fermented dairy products and contains live bacterial cultures, Buttermilk is produced by fermentation as lactic acid bacteria, and also different types of cheese, but only aged cheese have live cultural bacteria. Furthermore, prokaryotes help in the production of sour cream, pickles, olives, vinegar and sourdough bread. Why, because prokaryotes are useful to some food production by converting textures, providing flavors, manufacturing ethanol, and protection from unwanted microbes known as food preservation. Food preservation is a method that is projected to keep microorganisms out of foods, removing microorganisms from contaminated foods, and obstruct the growth and activity of microorganisms already in foods. Also, bacteria breakdown proteins and fats into a complex mix of amino acids amines, and fatty acids, which lead to processing altars, the food product.
Food safety is a quite hot topic and important public health issue all over the world. Food-borne disease can cause serious harm. Millions of people suffered from diseases and even died because of having unsafe food.
Food safety culture society can be considered of comparable significance (3)to administrative consistence and client benefit . On the off chance that any of these three perspectives fizzle , the business itself could come up short (Ungku Zainal Abidin et al , 2013 ) . Numerous businesses additionally lift security to the same or even a larger amount of significance than these as no business can exist without representatives . Food safety highlights in the work environment is another great case of the significance of value affirmation in the public eye today (Taylor , 2011 ) . Regardless of whether it is the honesty of a security bridle for working at statures or the water testing for the city , quality estimations , preparing and framework arrangement can all straightforwardly influence workers and even open (4)wellbeing (Griffith , 2012 ) . Food safety is a logical idea portraying and dealing with , readiness , and capacity of foods in ways that anticipate foodborne disease . This incorporates various schedules that ought to be taken after to stay away from conceivably extreme (5)wellbeing perils (Roberts et al , 2012 )
Food is a product that is rich with nutrient and can be contaminated with exposed to major source such as water, air, dust, sewage, insects and rodent (Oi Nee and Norrakiah, 2011). As a food handler they need to handle the changes in preparation techniques and food production because the fact remains whereby food is the source for microorganism which can cause illness (Oi Nee and Norrakiah, 2011).
Each and every year millions of people become sick because of food poisoning and other food related illnesses. Many of these illnesses can easily be prevented by properly cooking and handling food in the kitchen. Unfortunately, many people around the world are unaware of the consequences that can occur from contaminated and undercooked food. It is important for every individual who is planning on making a meal in their life (virtually everyone) to understand how to properly prepare their meal.
Handling, processing, and preparation such as (cooking, cooling, reheating, holding/service) should be controlled to ensure that the food is not contaminated in any way.
