It can be caused by raw meat coming in contact with already prepared food or unwashed food, and undercooked food. The main cause of salmonella is coming in contact with feces from a person or animal. As gross as this sounds it does happen due to people not washing their hands, thus causing salmonella to enter the body and go into the intestines and that is where it lives until killed. It is a very small bacteria that cannot be seen by the human eye just by microscope. Salmonella is very serious when it is contacted and can be deadly, so make sure you follow proper hygiene to ensure that you are getting any bacteria off of your food and hands.
Viruses The virus that most commonly causes gastrointestinal illness is the norovirus. It is easily transmitted from person to person, from contaminated food or water. Raw shellfish, particularly oysters, can also be a source of viral contamination. Infected people can also contaminate food if they do not wash their hands properly after going to the toilet and they then handle food. Parasites In the UK, food poisoning from parasites is rare.
If the bacteria enter the small intestine, they use their flagella to propel themselves through the lining of the intestinal wall, they produce a toxic protein. One part binds to specific carbohydrate receptors on cell-surface membrane; the toxic part enters the epithelial cells. This causes ion channels to open and Chloride ions flood into the lumen of intestine. Water then follows them into the lumen which causes watery faeces (diarrhoea) and dehydration4. Because of the improvements in sanitation and hygiene in the last 100 years, Cholera has been wiped out of England and much of the rest of the world3.
Contamination with pathogenic bacteria from the human/animal reservoir can occur when the landing place is unhygienic or when the fish are washed with contaminated water. Upon the processing of fish, its exposure to water is a critical part as pathogens may be present in the water used which can cause contamination and spoilage (Shoolongela & Schneider, 2012). Contamination of food can occur because of problems in food production, preparation, storage or cooking. The aquatic environment and soft tissue of fishes make it extremely susceptible to microbial contamination. Contamination commonly occurs in the environment in which the seafood (fish) is usually caught, during harvesting, and preparation (Wekell, Manger, Kolburn, Adams & Hill, 1994).
An estimated 73,000 cases of infection and 61 deaths occur in the United States each year. Infection often leads occasionally to kidney failure. Most illness has been associated with eating undercooked, contaminated ground beef. Escherichia coli are used in order to synthesize DNA and proteins. E.coli are thought to make vitamin K in the intestine , this vitamin is important in blood clotting
Unit 3 D1: Recommendations in relation to identify hazards to minimize the risks to the service user groups 1. Feeling sick or being sick Feeling sick or being sick can contaminate the pool and can pose a serious health risk to the staff and students at Ivy house. If not attended to the pool can become a fertile breeding ground for bacteria that can cause a wide range of illnesses. For example a parasite called cryptosporidium is excreted when faeces enters the water. This can cause really bad and severe diarrhoea, sickness, stomach cramps and fever.
Salmonella infection may spread from the intestines to the bloodstream and then to other body sites and can cause death unless the person is treated promptly with antibiotics. Older adults, infants, and those with impaired immune systems are more likely to have a severe illness from Salmonella infection. We have many steps to reduce the infection. Firstly, the first step is Consumers should check their homes, including their freezers, for recalled ground beef products and not eat them; restaurant and food service operators should not serve it. Consumers with questions about recalled ground beef products may contact Hannaford's Customer Information Center; 8 a.m. to 8 p.m. at telephone number (800) 213-9040, and choose option 6.
E-coli O157 is a form of food poisoning caused by a particularly virulent type of Escherichia coli bacteria which typically results in diarrhoea. How do people get it? From any of the following sources: • Handling raw meet, especially beef • Eating undercooked meat or poultry or other contaminated food product • Consuming untreated milk or dairy products • Swimming in or drinking unchlorinated water • Direct contact with animals particularly on farms or in animal sanctuaries • Close contact with another infected person When do people get it? The illness usually occurs within 3-8 days of infection, but 3-4 days is normal. What are the signs and symptoms?
Symptoms can range from mild to severe and include upset stomach, abdominal cramps, nausea and vomiting, diarrhea, fever, and dehydration. Food-borne diseases are constantly changing due to microorganisms evolving to adapt to its environment, food production practice changing, and newly microbes are being discovered that were unrecognized before. The most common food-borne diseases that occur in fast food production are Campylobacter, Salmonella, and E. coli 0157:H7, which occur when meat is eaten that is not fully cooked or is contaminated by the viruses. A food-borne disease known as Bovine Spongiform Encephalopathy, also known as Mad Cow Disease is the most common virus caused by ranchers. The human form of the disease is known as new variant Creutzfeld-Jacob Disease.
For example, tomatoes are injected with fish gene to make a new product with better quality because the components in fish can protect fruit from freezing. Nevertheless, this matter can cause a serious consequence for people who get allergic with fish. Hence, labeling will allow consumers to identify and steer clear of food products that could cause them problems. Last but not least, labeling GM foods
