What is a Foodborne Illness?
Also known as “food poisoning”
Costly, preventable disease caused by microbes or pathogens that contaminate food.
1 in 6 Americans each year contract one of these illnesses by eating contaminated foods or beverages.
CDC estimates that over 48 million people are infected with a Foodborne illness each year, causing 128,000 hospitalizations and over 3000 deaths.

Foodborne illnesses
There are over 250 Foodborne diseases, most of which are infections caused by bacteria, viruses, and parasites found in food.
Other diseases can be caused by poisonings, which are harmful toxins or chemicals, such that are found in poisonous mushrooms.

How does food become contaminated?
Naturally, bacteria is present throughout the environment in soil, water, and in the bodies of people and animals.
Food can become contaminated as it is produced and prepared.
![Page 5: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/5.jpg)
•Many healthy animals contain microbes in their intestinal tracts, that can contaminate meat products during slaughter and production.•Fruits and vegetables can become contaminated if they are washed with water that is contaminated with animal feces or human sewage.•Oysters and other filter feeding shellfish can concentrate bacteria that are naturally present in sea water, or other microbes that are present in human sewage dumped into the sea.
Causes of illness in 1,565 single food commodity outbreaks, 2003–2008 (cdc.gov)

How does food become contaminated cont.
During food processing, food can become contaminated by the humans who handle it.
Food handlers infected with a disease, who do not wash their hands, can contaminate food sources
Cross contamination between different food sources
Fully cooked foods that come into contact with other raw foods that contain pathogens
![Page 7: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/7.jpg)
What are the most common Foodborne diseases?
Norovirus
Salmonella
Listeria
Campylobacter
E.Coli
![Page 8: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/8.jpg)
Norovirus
One of the leading causes of Foodborne illness in the United States
Easily transmitted from one person to another
70% of infected food workers cause about 70% of reported Norovirusoutbreaks from contaminated food.
Symptoms Inflammation of the
stomach/intestines
Vomiting, diarrhea, nausea, stomach pain, fever, headaches, body aches
Most people develop symptoms within 12-48 hours of exposure
![Page 9: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/9.jpg)
Norovirus
Transmission
Highly contagious, and anyone can become infected
Easily transmitted by eating foods or liquids contaminated with the virus
Touching contaminated surfaces or objects
Having contact with someone with the virus
Treatment
No specific treatment since it is not a bacteria and cannot be treated with antibiotics
Dehydration is the major concern from vomiting and diarrhea
Drink plenty of fluids, water, and sports drinks that do not contain caffeine or alcohol
![Page 10: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/10.jpg)
Salmonella
One of the most common and widely distributed disease-causing bacteria
Over 2,500 strains of salmonella
Many strains are antibiotic resistant
Young children, older adults, and people with weakened immune systems are most vulnerable populations
Symptoms Occur 12-72 hours after
infection and lasts 4-7 days
Diarrhea, vomiting, fever, and abdominal cramps
Hospitalization may be necessary for severe symptoms
If it becomes invasive, the infection will spread to the intestines to the blood stream, bone, joint, brain, or nervous system which can cause death (only 8% of cases)
![Page 11: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/11.jpg)
Salmonella
Transmission
Widely present in domestic and wild animals, mostly food animals (pigs, poultry, and cattle)
This bacteria can pass through entire food chain, from animal feed, primary production, and into households and restaurants
Eating contaminated food of animal origin
Fecal-oral transmission
Treatment
Typically clear up within seven days with proper hydration
At risk populations may require antibiotics to prevent the spread of infection
However, many types of salmonella are antibiotic resistant
![Page 12: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/12.jpg)
Listeria
Bacterial infection
Tends to affect older adults, pregnant women, children, and people with weakened immune systems
CDC estimates 1600 illnesses and 260 deaths from Listeria have occurred in the United States
Incidence rate in 2013 was 0.26 per 100,000 people
Symptoms Fever and muscle aches,
diarrhea, headache, stiff neck, loss of balance, and convulsions
Most people diagnosed have an invasive infection, meaning that it spreads beyond the gastrointestinal tract
In pregnant women, it can cause miscarriage, stillborn, premature labor, or a life threatening infection of the newborn
![Page 13: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/13.jpg)
Listeria
Transmission Caused by the bacteria
Listeria Monocytogeneswhich is commonly found in soil and water
Animals can carry the bacterium without showing signs of illness
If this bacteria gets into a factory of food production, it can stay there for years
Eating a contaminated food source
Treatment At risk populations should
seek medical attention immediately
Those who think they are infected, but do not have symptoms generally do not need any treatment
Proper hydration
![Page 14: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/14.jpg)
Campylobacter
Infectious disease caused by the bacteria genus Campylobacter
Best grown in places where the oxygen is lower than the amount in the environment and temperatures between 37 degrees and 42 degrees C
Many cases go undiagnosed and unreported
Affect over 1.3 million people a year in the United States
Symptoms Occur within 2-5 days of
becoming infected Diarrhea, cramping, nausea,
vomiting, abdominal pain, and fever
Bloody diarrhea may occur Older adults and people with
weakened immune systems may have an invasive infection, which spreads to the bloodstream and may be life threatening
![Page 15: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/15.jpg)
Campylobacter
Transmission Only takes a few
organisms to become ill
Most commonly spread through drinking unpasteurized milk, eating raw or undercooked meat, or cross contamination
Infected produce and water sources
Eating contaminated meat products
Fecal-oral transmission
Treatment No formal treatment
necessary
Proper hydration
At risk populations may need antimicrobial therapy and antibiotics
![Page 16: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/16.jpg)
Escherichia Coli (E.coli)
Bacteria that is normally present in the intestines of humans and animals
However, some are pathogenic
Most common pathogenic types are the Shiga toxin-producing E.coli (STEC) and E.coli 0157
Most STEC infections come from outbreaks of E.coli0157
Symptoms
Usually occur three days after becoming infected
Diarrhea, cramping, vomiting, and fever
Most people get better within 5-7 days
Some cases can be life threatening
![Page 17: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/17.jpg)
Escherichia Coli
Transmission
Consumption of contaminated food or water
Drinking unpasteurized milk and unpasteurized apple cider
Contact with infected cattle
Fecal-oral transmission
Treatment
No specific medical treatment
Antibiotics should not be used to treat this illness
Proper hydration
![Page 18: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/18.jpg)
Foodborne Illness in the Summer
Foodborne illnesses tend to increase during the summer time
Microorganisms that cause disease tend to grow faster in the warm summer months
Grow fastest at temperatures ranging from 90 to 110 degrees F
Moisture in the air also causes bacteria to grow
![Page 19: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/19.jpg)
Foodborne Illness in the Summer
Given the right circumstances, harmful bacteria can multiply quickly and can contaminate food in large numbers
As outside activities increase during the summer (picnics, barbeques, and camping trips) there is a greater chance for food sources to be contaminated without the proper food safety measures
![Page 20: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/20.jpg)
Prevention Strategies
![Page 21: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/21.jpg)
CLEAN
Wash hands and surfaces often
Illness causing bacteria can live in many places in your kitchen, including your hands, utensils, and cutting boards
Wash hands with antibacterial soap for at least 20 seconds, scrubbing them thoroughly
Wash fruits and vegetables
![Page 22: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/22.jpg)
SEPERATE
Do not cross contaminate
Separate cutting boards, plates, and utensils for produce and meat, poultry, seafood, and eggs
Keep meat, poultry, seafood, and eggs separate from all other foods in the refrigerator
When shopping at the grocery store, keep meat products away from other products in the shopping cart
![Page 23: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/23.jpg)
COOK
Simply checking the color and texture is not a safe way to tell if food is cooked all the way
Use a food thermometer to check the internal temperatures
145 degrees for whole meats
160 degrees for ground meats
165 degrees for all poultry
During meal times, keep all foods hot and above 140 degrees while being served and eaten
![Page 24: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/24.jpg)
CHILL
Illness causing bacteria can grow in foods within two hours (one hour in the summer time), unless you refrigerate them
Refrigerate foods that tend to spoil quickly (poultry, meat, eggs, fruits and vegetables)
Foods in the refrigerator that have been cooled down should be kept at 40 degrees F or below
Thaw or marinate foods in the refrigerator, never on counter tops or in the kitchen sink
![Page 25: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/25.jpg)
Food Safety Tips
Do not eat or drink foods containing raw eggs or unpasteurized milk
If you are served undercooked meat in a restaurant, do not hesitate to send it back to the kitchen for further cooking
Wash hands thoroughly after coming into contact with raw meat or poultry
![Page 26: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/26.jpg)
Food Safety Tips
Avoid contact with animal or human feces
Avoid letting infants come into contact with raw meat
Clean and disinfect surfaces thoroughly
Store ready-to-eat foods (hot dogs and deli meat) safely, no longer than 2 weeks
![Page 27: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/27.jpg)
Food Safety Tips
If you are sick, do not prepare foods for others
Avoid swallowing water when swimming in pools, lakes, ponds, or backyard “kiddy” pools
When cooking and eating outside, store cold foods in a ice filled cooler at 40 degrees or below
![Page 28: Summer Food Safety KC](https://reader033.vdocuments.mx/reader033/viewer/2022051710/5a67d9987f8b9aa6128b5479/html5/thumbnails/28.jpg)
Report
If you believe you or someone you know is sick due to a Foodborne illness, contact your local Health Department.
Health departments are an important part of the food safety system and can find out important information on what may have made you sick
