Food Safety Myth #1
Module 1, Lesson 1
“If it tastes okay, it is safe to eat.”
FACT: You should never rely on your sense of smell, taste or sight to tell youif a food is safe to eat.
Food Safety Myth #2
Module 1, Lesson 1
“If you get sick from eating somethign, it was from the last food you ate.”
FACT: It can take anywhere from 30 minutes to six weeks to become sick from unsafe foods.
Food Safety Myth #3
Module 1, Lesson 1
“The worst that could happen to you with a food borne illness is an upset stomach.”
FACT: While an upset stomach is a common side effect of a bood borne illness, you can also experience fever, diarrhea, and dehydration. Other less common but more sever outcomes include paralysis, meningitis and even death.
Food Safety Myth #4
Module 1, Lesson 1
“I have never been sick form the food I prepare, so I don’t need to worry about feeding it to others.”
FACT: Some people are at greater risk for developing food borne illnesses. A food you can safely eat migh make other sick.
Infants, pregnant women, young children, older adults, individuals with weakened immune systems and those with certain chronic diseases fall into the “greater risk” category.
Food Safety Myth #5
Module 1, Lesson 1
“It is only in recent history that people have starteed to get sick from eating unsafe foods.”
FACT: Many incidents of food borne illness went undetected in the past.
Symptoms of nausea, vomiting and diarrhea were often (and still are) blamed on the flu.
Food Safety Myth #6
Module 1, Lesson 1
“If I left the lid on fodd that has been sitting out too long, it is safe to eat.”
FACT: Though food may be safe after cooking, it may not be safe later.
One bacterium left at room temperature for seven hours can grow into as much as 2,097,152 bacteria
Food Safety Myth #7
Module 1, Lesson 1
“If you let a food sit out more than two hours, you can make it safe by heating it to really high temperatures.”
FACT: Some bacteria, such as stphylococcus aureus (staph) produce toxins not destroyed by high cooking temperatures.
Food Safety Myth #8
Module 1, Lesson 1
“If a hamburger is brown in the middle, it is cooked to a safe internal temperature.”
FACT: One out of four hamburgers turn brown before it has been cooked to a safe internal temperature.
Research shows that some ground beef patties look done at internal temperatures as low as 57ºC/135ºF.

Definition
Pathogen
Module 2, Lesson 3
A bacterium, virus or other micro-organisms that can cause disease.
Definition
Food Borne Illness
Module 2, Lesson 3
An illness resulting from food contaminated by pathogenic bacteria, viruses, parasites, as well as chemical or natural toxins.
Definition
Microbes
Module 2, Lesson 3
Also know as micro-organisms. They are tiny living organisms that can only be seen through a microscope. Some microbes cause disease, while others are completely harmless.
Definition - Classes of Microbes
Neutral
Module 2, Lesson 3
Microbes that have no affect on food products and are harmless.
Definition - Classes of Microbes
Beneficial
Module 2, Lesson 3
Microbes that are required for a specific result when processing food or are required by our bodies (e.g., probiotics, molds – blue cheese, yeast)
Definition - Classes of Microbes
Pathogenic
Module 2, Lesson 3
Microbes that cause diseases. In some cases, it is not the microbe itself, but the toxin the microbe produces (e.g., botulism).
Definition - Classes of Microbes
Spoilage
Module 2, Lesson 3
Microbes (or enzymes) that tend to degrade a food item’s proteins, carbohydrates or fats (e.g., molds – bread).
Types of Micro-Organisms: Bacteria
Module 2, Lesson 3
- Bacteria is everywhere – in the air we breathe, the water we drink, in the soil and in our bodies. Most bacteria are harmless.
- Bacteria reproduces by dividing in two (fission).
- They can form spores in times of adverse conditions.
- Bacterial spores can form, hibernate and then become active in conditions that favour them. Examples of this can be found in Salmonella, Staph and E. Coli.
Types of Micro-Organisms : Viruses
Module 2, Lesson 3
- Viruses are parasites that are the smallest of all micro-organisms.
- A virus needs a host to multiply but can survive for long periods of time under harsh conditions (such as drying, freezing, pasteurization).
- Once a host is found, a virus can start to reproduce (e.g., Norwalk, Hepatitis A).
Types of Micro-Organisms : Parasites
Module 2, Lesson 3
Single or multi-celled organisms that depend on other animals or humans for survival.
Parasites use their living host as a source of nutrients or as a place to live.
Possible sources include:
* Meat
* Seafood
* Water
* Infected food handlers
Types of Micro-Organisms : Molds
Module 2, Lesson 3
Molds are microscopic fungi that live on plants or animal matter, whose spores are transported by water, air and insects. They sometimes can be seen with the naked eye, but not always.
When mold is visible, it is the mold’s spores that give it its colour.
Mold has branches and roots. The roots may not be visible, but they can travel deep into food (e.g., aspergillus, penicillium).
Types of Micro-Organisms : Molds
Module 2, Lesson 3
Yeasts are slightly larger than bacteria and reproduce through budding. One cell can produce several buds. When the buds fall off, they form a new cell.
Yeasts will grow on most foods, on equipment and walls where there are small amounts of food and moisture.
Examples include saccharomyces cerevisiae, that can be found in the winemaking, baking and brewing processes.
What is the mnemonic / acronym to help remember the conditions for microbial growth?

FAT TOM - Food
What foods are a higher risk when it comes to bacterial growth?
Module 2, Lesson 4
Foods that are considered potentially hazardous, like meat, seafood, dairy, eggs and cooked foods, are higher in protein & carbohydrates. Protein and carbohydrates are the main food sources of bacteria.
FAT TOM - Acidity
How does acidity affect bacterial growth?
Module 2, Lesson 4
(pH) is a term describing how acidic or alkaline a product is.
Bacteria will rapidly grow at pH 7 but as pH declines below 4.6 bacterial growth slows.
Most foods are in the acidic range (pH 4.6 – pH 7).
FAT TOM - Temperature
What is the temperature danger zone?
Module 2, Lesson 4
Products should be kept cold (below 4C / 40F) or hot (above 60C / 140F).
The range between these two temperatures is known as the
danger zone (4C – 60C).
FAT TOM - Temperature
Why is it so important to know the temperature danger zone?
Module 2, Lesson 4
75% of food borne illness can be traced to poor temperature control.
* Metric (Celsius)
* 4 – 60 degrees
- Imperial (Fahrenheit)
- 40 – 140 degrees

FAT TOM - Time
How does time factor into microbial growth?
Module 2, Lesson 4
Time and temperature work together to control microbial growth.
A small amount of temperature abuse can occur as long as attention is paid to the amount of time a product spends at improper temperatures.
FAT TOM - Time
In Alberta, what is the time limit for foods in the danger zone?
Module 2, Lesson 4
In Alberta, potentially hazardous foods have a two hour limit if kept in the danger zone. This two hours is cumulative of any time in the danger zone and foods must be discarded if surpassed.
FAT TOM - Time
Definition: Lag Phase
Module 2, Lesson 4
The time it takes for the microbes to get used to its new environment, approx. 2 to 4 hours.
FAT TOM - Time
Definition: Log / Growth Phase
Module 2, Lesson 4
Microbes double in number about every 20 minutes.
FAT TOM - Time
Definition: Stationary Phase
Module 2, Lesson 4
Growth ends, but bacteria live.
FAT TOM - Time
Definition: Death Phase
Module 2, Lesson 4
Bacteria will begin to die off and be eliminated.
Guidelines for chilling food.
Module 2, Lesson 4
Food must be cooled from 60C (140F) to 20C (68F) in less than two hours.
Continued chilling will cool foods from 20C (68F) to 4C (40F) in less than four hours.
All goods must spend less than 6 hours in the danger zone.
Improper cooling of food is one of the main processes that causes foodborne illness. The faster food can be cool, the better to reduce the amount of time spent in the danger zone. Food handlers need to be active in cooling techniques and ensure the temperature is being checked frequently during the process. If the temperature is too high at either of the time limits, the food needs to be discarded
FAT TOM - Oxygen
What are aerobic microbes’ oxygen requirments?
Module 2, Lesson 4
Requires oxygen to grow, such as staph and molds.
FAT TOM - Oxygen
What are anaerobic microbes’ oxygen requirments?
Module 2, Lesson 4
Requires no oxygen, such as botulism.
FAT TOM - Oxygen
What are facultative anaerobic microbes’ oxygen requirments?
Module 2, Lesson 4
Can live and grow with or without oxygen, like salmonella and yeasts.
FAT TOM - Moisture
How can we control microbial growth?
Module 2, Lesson 4
We can control microbial growth cy controlling water activity (Aw).
Most foods have an Aw greater than 0.95 (considered perishable foods) which supports the growth of microbes (bacteria, molds, yeasts).
Fresh meat and fish have an Aw of 0.99
FAT TOM - Moisture
Name some examples of how to slow or inhibit bacterial growth
Module 2, Lesson 4
The use of sugar, salt and dry methods to reduce the water activity will inhibit microbial growth by limiting the amount of free water Examples such as sugar and salt for curing meats are methods of preservation.
What are some of the symptoms of foodborne illness?
Module 3, Lesson 5
- Fever
- Abdominal pain
- Diarrhea
- Nausea
- Vomiting
- Dehydration
Age, general state of health, how contaminated the food and how much was consumed can all affect how a person experiences foodborne illness
How are foodborne illnnesses caused?
Module 3, Lesson 5
Illness is caused by the ingestion of food that is contaminated with infectious microorganisms. This is a direct result of bacterial action on the body.
This process is slow as the microbes need time to multiply.
Some bacteria, all viruses, and all parasites cause foodborne illness from infection.
What are 4 infectious bacterial diseases?
Module 3, Lesson 5
- Salmonella
- Campylobacter Jujuni
- Listeria Monocytogenes
- E. Coli O157:H7
Where is salmonella usually found?
Module 3, Lesson 5
Usually poultry and eggs, but recently vegetables, nuts and some sprouts have been reported
What is salmonella’s incubation period?
Module 3, Lesson 5
Two days, usually 12 – 72 hours
