    Study Notes

    Foodborne Illness Statistics

    • Globally, unsafe food causes 600 million cases of foodborne diseases and 420,000 deaths annually.
    • 30% of foodborne deaths are among children under 5.
    • 33 million years of healthy life are lost annually due to unsafe food.
    • One in 10 people globally become ill from contaminated food.
    • In Canada, 1 in 8 people get sick from contaminated food each year.
    • This results in over 11,500 hospitalizations and 240 deaths annually in Canada.
    • Diarrheal diseases are the most common type of foodborne illness.
    • Diarrheal diseases account for roughly 50% of foodborne illnesses and deaths globally.
    • In the US, approximately 1.35 million foodborne illnesses arise from food-source products annually.
    • In the US, 61% of foodborne diarrhea or vomiting outbreaks are spread by direct contact.
    • Norovirus is the leading cause of foodborne diarrhea or vomiting outbreaks.
    • 3 out of 4 norovirus outbreaks happen in long-term care facilities.
    • In Canada, 1 million illnesses, 1,180 hospitalizations, and 21 deaths are reported annually due to norovirus.
    • In the US, 1.35 million foodborne illnesses arise from food-source products annually.

    Common Foodborne Illnesses

    • E. coli is also a major cause of foodborne illnesses in both the U.S. and Canada, with significant but varied statistics depending on the specific strain.
    • Listeriosis causes roughly 1,600 illnesses, 94% hospitalization rate and 178 infections in Canada each year.

    Sources of Foodborne Illness

    • Meat and poultry
    • Milk
    • Fish and seafood
    • Fruits, vegetables, and cereals
    • Ready-to-eat foods
    • Raw flour
    • Fresh and frozen produce
    • Dairy and beef products
    • Eggs (e.g., raw eggs)
    • Raw milk
    • Various types of pet treats, including pig ears
    • Various types of poultry, including backyard chickens
    • Raw meat, dairy products, produce, and contaminated water are sources for various common causes of foodborne illness.

    Contamination Routes

    • Cross-contamination: transfer of bacteria from one source to another (e.g. using the same cutting board for raw and cooked meat)
    • Improper handwashing: transfer of pathogens from infected humans handling the food
    • Inadequate cooking temperatures: failure to reach sufficient temperatures to kill harmful bacteria, parasites and viruses.
    • Contaminated water: microorganisms that can cause illness
    • Consumption of undercooked meat, unpasteurized or improperly stored/handled dairy products, and contaminated water.
    • Contaminated food from an unsafe source.
    • Animal waste: microbes are prevalent in livestock.
    • Fecal material is a route of pathogen transfer to food products, frequently implicated in foodborne outbreaks.
    • Handling of contaminated animals.
    • Improper storage of foods.
    • Contact with infected pets or farm animals (e.g. reptiles and birds).
    • Handling contaminated pet foods or pet treats (e.g., pig ears).
    • Improper food handling practices at all stages of the food chain; from farm to table can cause food contamination.

    Food Safety Measures

    • Wash hands thoroughly with soap and water after handling raw meat, poultry, seafood, vegetables or handling pets.
    • Separate raw and cooked foods.
    • Cook food to proper temperatures.
    • Refrigerate or freeze foods promptly.
    • Wash produce thoroughly.
    • Avoid contaminated food from unsafe sources.
    • Thoroughly wash utensils and surfaces that come in contact with raw food.
    • Employ safe food handling practices at all stages of food preparation to limit risk of contamination.
