Food Borne Illness & Allergies
Bacteria Defined…
Any of a uni-cellular prokaryoptic microorganism of the class of schizoycetes, which
vary in terms of morphology , oxygen &
nutrient requirements, and mobility , which
may be free-living saprophytic or
pathogenetic in plants or animals; first used
in 1847…
Food Safety:
•
Food Borne Illness (or food poisoning):
occurs when a person get sick by eating
food that has been contaminated with
bacteria, parasites or viruses.
There are approximately 2 million cases of
food-borne illness in Canada each year…
Symptoms include stomach pain, diarrhea,
nausea, chills, fever, and headache; often
mistaken for the flu…
Food Borne Illness…
96 – 99% of food-borne illness and related
deaths go unreported! Why? People are
simply not aware of the symptoms…
The prevelance of food-borne illness can be
reduced and avoided by following simple
food safety procedures…
Food Allergies…
B) A Food Allergy is caused by a
hypersensitive immune system. The body
reacts as if a foreign substance (such as a
germ) has entered it.
Food Intolerance…
C) A Food Intolerance involves the digestive
system, but not the immune system. E.g.
Lactose intolerance…
90% of allergic reactions are caused by milk,
eggs, wheat, peanuts, soy, treenuts
(almonds, walnuts), fish and shellfish…
Symptoms…
Symptoms of allergies include: tingling
sensation in the mouth, swelling of the
tongue & throat, trouble breathing, hives,
vomiting, cramps, diarrhea, reduced blood
pressure, loss of consciousness, and death…
Treatment…
There is no treatment for allergies other than
AVOIDANCE of the food that causes an
allergic reaction. Someone with allergies
much be careful to read food labels!
Anaphylactic Shock…
Anaphylactic Shock occurs when a substance
causes a severe allergic reaction in the body.
Often a person’s airways will close off
completely. In these cases it is important to
use an Epi-pen (epinephrine) and call 911
immediately. In some cases, two doses of
epinephrine may be required…
Food thermometers..
Why use a food thermometer?
• It is the only reliable way to make sure that
food is cooked to safe temperatures;
• To be safe, foods must be cooked to an
internal temperature high enough to destroy
any harmful bacteria;
• Colour is not a reliable indicator – E.g.
Hamburger may turn brown before it reaches
an internal temperature of 71°C or higher…
Safe Food Temperatures…
“KEEP HOT FOODS HOT!”
(above 60°C)
“KEEP COLD FOODS COLD!”
(below 4°C)
DO NOT keep foods in the Danger Zone!
(between 4-60°C) where bacteria can grow &
multiply…
Refrigeration is also important – refrigerator
should be kept colder than 8°C!
Freezer should be set at -18°C
What are the different types of
Food Thermometers?
There are several types including: dial ovensafe, digital instant-read, fork, dial instantread, thermocouple, disposable temperature
indicators (single use), pop-up and ovenprobes with cords…
Summary: How to Prevent FoodBorne Illness…
• Keep HOT foods HOT and COLD
foods COLD! Use a food thermometer…
• Keep yourself & the work area clean – keep
pets out of the kitchen!
Thaw frozen foods in refrigerator or
microwave oven – not on
countertops;
• Don’t taste or eat food from a can or jar that
is bulging, damaged, or leaking…
• Boil home-canned foods 15 to 20 minutes
before tasting or eating…
• Before & After handling or cutting food,
wash your hands, the work area, and the
utensils before cooking…
