20、ter two: the contaminantsa. viruses1. the leading cause of food borne illness.2. viruses can survive cooler and freezer temperatures and are not destroyed by normal cooking temperatures. 3. viruses dont grow in food. but once eaten, they grow inside a persons intestines.4. viruses are carried by hum

21、ans and animals, and can transfer from person to person, from people to food and from people to food-contact surfaces. 5. people get viruses from food, water, or contaminated surfaces.6. foodborne illnesses from viruses typically occur through fecal-oral routes. 7. therefore the best way to prevent

22、food borne illness spread by viruses is to: a. keep food handlers who are vomiting or have diarrhea or jaundice from working and quick cleanup of vomit is important.b. make sure food handlers wash their hands.c. minimize bare hand contact with ready to eat food8. the 2 major food borne illnesses cau

23、sed by viruses are hepatitis a and norovirus gastroenteritis. b. bacteriathey live in and on our bodies; they cannot be seen, smelled, or tasted.1. conditions that favor bacterial growth are: “fat tom”. a. foodpathogens need an energy source, such as carbohydrates or proteins. b. acidity- pathogens

24、grow best in food that contains little or no acid: “a ph of 5-7. c. time: “the longer in the tdz, the greater the risk. d. temperature: “pathogens grow much faster between 70f and 125f”.e. oxygen “some pathogens are aerobic (requiring oxygen for growth), while some are anaerobic (not requiring oxyge

25、n for growth)”.f. moisture “0.85 or higher on the aw scale that measure water activity”.2. the best way to stop bacterial growth is to control conditions that favor that growth. the two conditions that you will be able to control are time and temperature. a. store food at temperatures outside the te

26、mperature danger zone (between 41 f and 135 f).b. minimize the amount of time food is in the temperature danger zone during preparation.c. dispose of any potentially hazardous foods that have remained in the tdz for more than four hours.d. cook food to minimum internal temperatures3. the food and dr

27、ug administration has identified 3 bacteria in particular that are highly contagious and can cause severe illness.a. salmonellab. shigellac. e. colic. fungicooking or freezing will not destroy toxins produced by toxic wild mushrooms. most of the foodborne-illness outbreaks are caused by the confusio

28、n between edible and wild mushrooms. d. parasitesillnesses from parasites are not as common as those caused by bacteria or viruses. parasites do share common characteristics: commonly associated with seafood, wild game, and food processed with contaminated water. cooking food to required minimum int

29、ernal temperatures is also important. e. physical and chemical hazards1. physicalbones, glass and metal pieces2. chemical contamination-foodservice chemicals can contaminate food if they are used incorrectly. a. cleaners, sanitizers and pesticides and common food allergies (milk, eggs, fish, nuts, a

30、nd preservatives).b. toxic metalsutensils that contain toxic metals can cause toxic-metal poisoning. if acidic food is stored in or prepared with this equipment, the metal can leach and cause the food to become contaminated. examples are lead, copper and zinc.c. chemicals used in foodservice can con

31、taminate food if they are used or stored the wrong way. cleaners, sanitizers, polishes and machine lubricants pose risks. d. store chemicals away from prep areas, food-storage areas, and service areas. chemicals must never be stored above food or food-contact surfaces. f. biological contaminates:1.

32、biological toxins that come from fish are:a. scromboid poisoningcomes from tuna, bonito, mackerel and mahi mahi. this occurs when fish have been time-temperature abused. when these conditions occur, the fish produce the toxin, histamine, which cannot be killed by cooking or freezing. b. ciguatera po

33、isoningfound in predatory reef fish such as barracuda, grouper, amberjack and red snapper. the toxins accumulate when these fish eat smaller fish that have eaten a type of toxic algae. symptoms are temp. blindness, nausea, itching, and dizziness.c. the best way to prevent both of these toxins from b

34、eing present in your kitchen is to buy your seafood supplies from approved sources. this is important because neither toxin can be destroyed by cooking. g. food allergensin the last 5 years the number of americans with a food allergy has risen from 6 million to 11 million. a food allergy is the body

35、s negative reaction to a food protein. 1. allergic reactions may occur immediately or several hours later. symptoms include: a. itching in and around the mouth, face, or scalpb. tightening in the throatc. shortness of breathd. hivese. swelling of the face, eyes, hands or feetf. vomiting and crampsg.

36、 loss of consciousnessh. death2. examples of common food allergens are:a. milk and dairy productsb. eggsc. fishd. shellfishe. wheatf. soyg. peanuts and tree nuts3. cooking around food allergens. it is of the utmost importance to address the prevention of cross-contact of food with potential food all

37、ergens during food preparation. to avoid cross contact be sure to wash, rinse and sanitize between uses. wash hands and change gloves before preparing food. and lastly, assign specific equipment for preparing food for customers with allergens. examples of cross-contact would include cooking shrimp a

38、nd chicken in the same oil and putting food on surfaces that have touched allergens can cause cross-contact. another example would be to put food on surfaces that have touched allergens. h. the fda has developed the alert system for minimizing the danger of tampering with your food supplies:1. assur

39、e - that products you receive are from safe sources. 2. look - monitor the security of products in the facility.3. employees - know who is in your facility.4. reports - keep information related to food defense accessible.5. threat - identify what you will do and who you will contact if there is susp

41、ithout admitting responsibility or accepting liability. 3. recoverywork with the regulatory agency to resolve issues. set the suspected product aside if any remains. include a label with do not use and do not discard on it. investigate to find the cause of the outbreak. develop a plan to reassure cu

42、stomers that the food you serve is safe. j. how contamination happens1. contaminants come from a variety of places. contaminants come from animals we use for food, from the air, contaminated water, and dirt. 2. most food is contaminated accidentally. it happens because of the way people handle food

43、contact surfaces. it you dont wash your hands after using the restroom then anything you touch can become contaminated. this is called the fecal-oral route.3. food handlers can pass on contaminants when they are in contact with a person who is ill. 4. contamination can happen in a variety of ways.a.

44、 from person to personb. through sneezing or vomiting onto food or food-contact surfacesc. from touching dirty food-contact surfaces and equipment, and then touching food.chapter 3: the safe foodhandlera. how foodhandlers can contaminate food; any of the following situations can lead to contaminatin

45、g food:1. when they have a foodborne illness2. when they have wounds that contain pathogens3. when they have contact with a person who is ill4. when they touch anything that may contaminate their hands and then dont wash them. 5. when they have symptoms such as diarrhea, vomiting, or jaundicea yello
