You Can Prevent Contamination Objectives: 2-2 Biological, chemical, and physical contaminants and how to prevent them How to prevent the deliberate contamination of food How to respond to a foodborne-illness outbreak Common food allergens and how to prevent reactions to them How Contamination Happens

Contaminants come from a variety of places: 2-3 Animals we use for food Air, contaminated water, and dirt People o Deliberately o Accidentally How Contamination Happens

People can contaminate food when: 2-4 They dont wash their hands after using the restroom They are in contact with a person who is sick They sneeze or vomit onto food or food contact surfaces They touch dirty food-contact surfaces and equipment and then touch food

Biological Contamination Microorganism: Small, living organism that can be seen only with a microscope Pathogen: Harmful microorganism Make people sick when eaten or produce toxins that cause illness Toxin: 2-5 Poison Biological Contamination Four types of pathogens can contaminate food and cause

foodborne illness: Bacteria 2-6 Viruses Parasites Fungi Biological Contamination Common symptoms of foodborne illness: Diarrhea Vomiting

Fever Nausea Abdominal cramps Jaundice (yellowing of skin and eyes) Onset times: 2-7 Depend on the type of foodborne illness

Can range from 30 minutes to six weeks The Big Six Pathogens Food handlers diagnosed with illnesses from the Big Six pathogens cannot work in a foodservice operation while they are sick. Shigella spp. Salmonella Typhi Nontyphoidal Salmonella (NTS) Shiga toxin-producing Escherichia coli (STEC), also known as E. coli Hepatitis A

Norovirus 2-8 Bacteria: Basic Characteristics Location: Found almost everywhere Detection: Cannot be seen, smelled, or tasted Growth: Will grow rapidly if FAT TOM conditions are correct

Prevention: 2-9 Control time and temperature What Bacteria Need to Grow F T Food Acidity Temperature T O M

Time 2-10 A Oxygen Moisture What Bacteria Need to Grow Food: Most bacteria need nutrients to survive TCS food supports the growth of bacteria better than other types of food F Food

2-11 What Bacteria Need to Grow Acidity: Bacteria grow best in food that contains little or no acid A Acidity 2-12 What Bacteria Need to Grow Temperature: Bacteria grow rapidly between 41F and 135F (5C and 57C) o

2-13 This range is known as the temperature danger zone Bacteria growth is limited when food is held above or below the temperature danger zone T Temperature What Bacteria Need to Grow Time: Bacteria need time to grow The more time bacteria spend in

the temperature danger zone, the greater chance they have to grow to unsafe levels. T Time 2-14 What Bacteria Need to Grow Oxygen: Some bacteria need oxygen to grow, while others grow when oxygen isnt there O Oxygen 2-15 What Bacteria Need to Grow Moisture:

2-16 Bacteria grow well in food with high levels of moisture aw = water activity; the amount of moisture available in food for bacterial growth aw scale ranges from 0.0 to 1.0 Water has a water activity of 1.0 M Moisture

Control FAT TOM The conditions you can control: Temperature o Time o 2-17 Keep TCS food out of the temperature danger zone Limit how long TCS food spends in the temperature danger zone Major Bacteria That Cause Foodborne Illness The FDA has identified four types of bacteria that cause severe illness and are highly contagious: 2-18

Prevention Measures Food easily contaminated by hands, such as Exclude food handlers who have diarrhea salads containing TCS food (potato, tuna, and have been diagnosed with an illness shrimp, macaroni, chicken) caused by Shigella spp. from the operation Exclude food handlers who have diarrhea from the operation Food that has made contact with contaminated water, such as produce Wash hands Control flies inside and outside the operation 2-21 Major Bacteria That Cause Foodborne Illness Bacteria: Shiga toxin-producing Escherichia coli (ess-chur-EE-kee-UH-KO-LI), also known as E. coli Source: Intestines of cattle; infected people Food Linked with the Bacteria

Prevention Measures Ground beef (raw and undercooked) Contaminated produce Exclude food handlers who have diarrhea and have been diagnosed with a disease from the bacteria Cook food, especially ground beef, to minimum internal temperatures Purchase produce from approved, reputable suppliers Prevent cross-contamination between raw meat and ready-to-eat food 2-22 Viruses: Basic Characteristics Location: Carried by human beings and animals o

Require a living host to grow o Do not grow in food o Can be transferred through food and remain infectious in food Sources: 2-23 Food, water, or any contaminated surface Typically occur through fecal-oral routes Viruses: Basic Characteristics

Destruction: 2-24 Not destroyed by normal cooking temperatures Good personal hygiene must be practiced when handling food and food-contact surfaces Quick removal and cleanup of vomit is important Major Viruses that Cause Foodborne Illnesses The FDA has identified two viruses that are highly contagious and can cause severe illness:

Hepatitis A Norovirus Food handlers diagnosed with an illness from hepatitis A or Norovirus must not work in an operation while they are sick. 2-25 Major Viruses That Cause Foodborne Illness Virus: Hepatitis A (HEP-a-TI-tiss) Source: Human feces Food Linked with the Virus Prevention Measures Ready-to-eat food Exclude staff who have been diagnosed with hepatitis Shellfish from contaminated water A from the operation.

Exclude staff who have jaundice for seven days or less from the operation. Wash hands. Avoid bare-hand contact with ready-to-eat food. Purchase shellfish from approved, reputable suppliers. 2-26 Major Viruses That Cause Foodborne Illness Virus: Norovirus (NOR-o-VI-rus) Source: Human feces Food Linked with the Virus Prevention Measures Ready-to-eat food Exclude staff who are vomiting or have diarrhea and Shellfish from contaminated water have been diagnosed with Norovirus from the operation. Wash hands. Avoid bare-hand contact with ready-to-eat food. Purchase shellfish from approved, reputable suppliers.

2-27 Parasites: Basic characteristics Location: Require a host to live and reproduce Source: 2-28 Seafood, wild game, and food processed with contaminated water, such as produce Parasites: Basic characteristics Prevention: 2-29

Purchase food from approved, reputable suppliers Cook food to required minimum internal temperatures Fish that will be served raw or undercooked, must be frozen correctly by the manufacturer Fungi: Basic Characteristics Yeasts, molds, and mushrooms: 2-30 Some molds and mushrooms produce toxins

Throw out moldy food, unless mold is a natural part of the food Purchase mushrooms from approved, reputable suppliers Biological Toxins Origin: Naturally occur in certain plants, mushrooms, and seafood Seafood toxins: 2-31
