1. How does food poisoning occur? Food poisoning is the illness caused by eating food contaminated with harmful bacteria. A bacterium basically needs warmth‚ moisture‚ food‚ and time. If it gets all this then it can grow and multiply very quickly. The danger zone for bacterial growth is between the temperatures 5 and 60°C the most critical temperatures being between 21 and 40.There are many types of food poisoning bacteria that cause a variety of symptoms and which last for different periods of

Safe Food Handling Alternate Names food safety food sanitation and hygiene Definition Safe food handling practices limit the risk of foodborne illnesses or food poisoning. Culprits of foodborne illness include produce‚ cooked and raw meat‚ eggs‚ and canned foods. What food source is the nutrient found in? If not handled properly‚ many foods can become contaminated with germs and organisms that make people sick when the food is eaten. Experts estimate that between 6.5 and 33 million cases of

STL 3 K10 SAFE FOOD HANDLING Good Hygiene Practise When preparing food it is essential that you keep yourself and your kitchen clean. Wash and dry your hands thoroughly before touching and preparing food and after touching raw foods especially poultry such as chicken. Always wash your hands after using the toilet or touching bins or pets. It is recommended that hair be tied back or covered while cooking. Wear a clean apron when cooking and remove it should you need to visit the toilet. Change

brain are not only determined by genetics‚ but also environment interaction. The existence of a gene does not mean that it is active. There are many variables that determine whether a gene will express itself and its psychological impact. For example‚ predisposition to post-traumatic stress disorder (PTSD) is related to whether certain stress genes are active or inactive during a traumatic event. A person

Chapter 1 – PROVIDING SAFE FOOD The Challenges to Food Safety The greatest danger is from foodborne illnesses‚ diseases that are carried or transmitted to people by food. Salmonella and Staphylococcus are two of the best known foodborne illnesses. An outbreak of foodborne illness is defined as an incident in which two or more people experience the same illness after eating the same food. Laboratory anlysis must then show that the food is the source of the illness. When botulism or chemically

Should there be limits to genetic modification of food? Should there be limits to genetic modification of food? It may seem very attractive to be able to genetically modify crops‚ but at what cost? Giant transnational companies are carrying out a dangerous global experiment by introducing large numbers of genetically engineered food into our diet. Genetic manipulations can result in unanticipated harmful effects‚ and because genetically engineered foods are not tested sufficiently‚ this experiment

Are genetically modified foods safe to eat? Nowadays‚ genetically modified crops are planted worldwide. According to Human Genome Project‚ over 10 million farmers in 22 countries are planting genetically modified crops on the fields. The total acreage has reached a quarter billion (2011). Apparently‚ genetically modified foods have prominent benefits so that more and more people are planting them and eating them. Genetically modified plants are able to resist pests and certain kinds of diseases

Genetic Discrimination Based on Testing For "Harmful" Genes Eugenics is a social philosophy which advocates the improvement of human hereditary traits through various forms of intervention. The goals have been to create healthier‚ more intelligent people‚ lessen human suffering and save society ’s resources. Sir Frances Galton‚ introduced the term "eugenics"‚ and is regarded as the founder of the modern science eugenics (Bennett). Earlier means of achieving these goals focused on selective breeding

2 Production of Protein from Cloned Genes Now that we have covered the basic techniques involved in gene cloning and DNA analysis and examined how these techniques are used in research‚ we can move on to consider how recombinant DNA technology is being applied in biotechnology. This is not a new subject‚ although biotechnology has received far more attention during recent years than it ever has in the past. Biotechnology can be defined as the use of biological processes in industry and technology

Organic Food: Is It Really Better? Americans usually do not think about what they eat. We do not acknowledge whether it is locally grown‚ sustainably raised‚ grass-fed‚ and free-range or pesticide free. Americans fail to realize the negative effects from the harmful pesticides‚ hormones‚ dyes and preservatives that are in our food. Conventional foods are produce that is grown with the use of many harsh chemicals before it is put into a supermarket. (The food we eat conventionally was meant to
