1. Introduction
From the very dawn of the mankind people have suffered from an array of infectious diseases. Advances in the ways of diagnostics and treatment allow us to ease this burden on the humanity. Information technology has provided scientific community with a chance to better control and, which is the most important, prevent foodborne diseases by gathering, analyzing and interpreting epidemiological data from a vast number of sites. Conclusions drawn as a result of such surveillance (trends in incidence, prevalence, endemicity of important pathogens, number of outbreaks, most common vehicles of infection, etc.) can be used to design intervention strategies to eradicate a disease as well as to assess a degree of success of food safety measures.
Initially, epidemiological surveillance was limited to scientific trials or a certain disease; collection of data on a wider, national, scale was passive. But even these scarce results were able to convince authorities in many countries to approach this issue seriously, in a systemic manner and with bigger amount of resources. In the USA the best known at the moment program, FoodNet or Foodborne diseases Active Surveillance Network, was launched on January 1, 1996. At first it covered only the territory with 13.2 million residents and required active collection of laboratory confirmed diagnoses on just seven potentially foodborne diseases all of which were caused by bacteria. According to the latest Preliminary FoodNet Data on the Incidence of Infection with Pathogens Transmitted Commonly Through Food in 2007 the active surveillance network covered confirmed diagnoses on 7 bacterial, 2 protozoal pathogens and one

Health and Social Care Level 3, Unit 3, P2

...Care settings Introduction: In this assignment, it is important to outline how legislation, policies and procedures relating to health and social Care influence health and Social Care settings. Definition of legislation: Legislation is a law or set of laws agreed by the government which must be followed and done. Definition of regulation: A principle, rule or law designed to control behavior. Food Safety Act (1990) The Food Safety Act was introduced in 1990 in response to public concern over the safety of food. This Act aims to control safety at all stages of food production. This legislation was also introduced in order to sell and keep food for sale which is unfit for people to eat. For example in a kitchen when staffs are placing foods in fridges and cupboards, they must ensure that the dates of the foods are up to date and checked properly. All food premises must be clean and free from rubbish, all equipment must be clean and good hygiene practices should be observed at all times. Under the Food Safety Act it is illegal to sell food unfit for human consumption. This means people may pass poor quality food off as good food to make money. The food safety Act 1990 influences health and social care settings so that Staffs check dates continuously on stocks to ensure that the foods are in good condition by checking that they are in the right place, and ensuring that there are no bugs or any insect in the food. The food safety Act 1990 also influences health and social...

Foodborne Nfections

...The Threat of Foodborne Infections The Threat of Foodborne Infections Foodborne infections pose a threat to everyone. Although the United States has one of the safest food supplies in the world, foodborne infections are relatively prominent in this nation. For example, there has recently been some contaminated produce, such as spinach and lettuce, which was distributed to numerous states that has caused a variety of unwanted symptoms and even resulted in death. This was widely reported in the news and had many individuals worried about what they were eating. Although the United States has many ways to combat the contamination of our food supply, it is still a threat to the nation. Foodborne infections can result from unsafe handling of food in the home, at the grocery store, at restaurants, as well as in many other places. Because foodborne infections are so easily transmitted, we need to be aware of how to protect ourselves and others from their harmful effects. Foodborne infections result from many different pathogens in our foods. These pathogens include bacteria, viruses, and parasites. It is estimated that there are 76 million illnesses, 325,000 hospitalizations, and 5,000 deaths in the United States each year due to foodborne infections. Montana statistics from 2005 reveal that there were 16 incidents and 693 cases of foodborne infections. (Mead et al., 2000). It is suspected that many cases of foodborne infections are not reported, either due to severity...

Sensory Science: Electronic Noses

...NAME LYNETTE CHIRIDZA COURSE SENSORY SCIENCE PROGRAM FOOD PROCESSING TECHNOLOGY LECTURER MR MPOFU ASSIGNMENT ONE QUESTION Describe and explain the working principle of electronic noses and their application in the food industry. ANSWER Analysis of odour and flavour in food has traditionally been performed either by a trained sensory panel or by head-space gas chromatography mass spectrometry. These methods are time consuming and costly and there is need in the food industry for objective automated non-destructive techniques that can characterize odour and flavour in food. New methods should allow a high number of samples to be analysed within a short period of time with a sufficient reproducibility and accuracy. During recent years there has been a rapid development of a concept named electronic nose (artificial nose) based on chemical gas-sensor array technology which seems to fulfil these requirements (Russell et al, 2001) The principle of operation of electronic noses is simple. Headspace gas from a sample is introduced to an array of sensors, which will respond to different degrees depending on the nature of the organic compounds present. The electronic nose derived its name because it in several aspects tries to resemble the human nose. Human olfactory perception is based on chemical interaction between volatile odour compounds and the olfactory receptors in the nasal cavity. The signals generated are transferred to the brain...
