10 Safety Myths
Don’t be
“myth”- led!
Following are
the facts for 10
common food
safety myths...
3
Myth 1
If it tastes
O.K., it's
safe to eat.
4
Fact 1
Don’t count
on these to
tell you if
a food is
safe to eat!
Smell
Taste
Sight
5
Estimates of foodborne illnesses
in the U.S. each year
76 million people
become ill
5,000 people die
6
Would this
many people
eat something if
they thought it
tasted, looked
or smelled bad?
7
Even if tasting would tell …
Why risk getting sick?
A “tiny taste” may
not protect you.
As few as 10 bacteria
could cause some
foodborne illnesses,
such as E. coli!
8
Myth 2
If you get sick
from eating a
food, it was
from the last
food you ate.
OOPS!
9
Fact 2
It can take
½ hour to
6 weeks to
become sick
from unsafe
foods.
10
You usually
feel OK
immediately
after eating
and become
sick later.
11
Foodborne illness is
NOT a pretty picture!
Hey guys,
I have to
throw up!
12
Myth 3
The worst that
could happen
to you with a
foodborne
illness is an
upset stomach.
13
Fact 3
Upset stomach
OOPS!
Fever
Diarrhea
Dehydration
(sometimes severe)
14
Less common, but
possible severe conditions
Meningitis
Paralysis
Death
15
Myth 4
If I’ve never been
sick from the
food I prepare, I
don’t need to
worry about
feeding it to
others.
16
Fact 4
Some people
have a greater
risk for foodborne
illnesses.
A food you can
safely eat might
make others sick.
Is the food safe
for everyone at
the table?
17
People with a higher risk for
foodborne illness
Infants
Pregnant
women
Young children and
older adults
People with weakened immune
systems and individuals with
18
certain chronic diseases
Myth 5
People
never
used to
get sick
from their
food.
19
Fact 5
Many incidents
of foodborne
illness went
undetected in
the past.
20
Symptoms of
nausea, vomiting,
and diarrhea were
often and still are
blamed on the "flu."
21
Foodborne illness vs. flu
More common in
foodborne illness:
Gastrointestinal
Nausea
Vomiting
Diarrhea
More common in
flu: Respiratory
Chest discomfort
Cough
Nasal congestion
Sore throat
Runny or stuffy
nose
22
23
Our food now
travels farther
with more
chances for
contamination.
In days gone by,
the chicken served
at supper may have
been in the hen
house at noon!
24
Myth 6
As long as I
left the lid on
a food that
has set out
too long, it is
safe to eat.
25
Fact 6
Though food may be safe after
cooking, it may not be safe later.
Just one bacteria in the food
can double in 20 minutes!
26
How many bacteria will
grow from one bacteria left at
room temperature 7 hours?
27
2,097,152!
28
Refrigerate
perishable
foods within
two hours at a
refrigerator
temperature of
40°F or lower.
On a hot day
(90°F or higher),
food should not
sit out for more
than one hour.
29
Myth 7
If you let a food
sit out more
than two hours,
you can make it
safe by heating
it really hot!
30
Fact 7
Some bacteria, such as staphylococcus
(staph), produce toxins not destroyed by
high cooking temperatures.
31
Myth 8
If a hamburger
is brown in the
middle, it is
cooked to a
safe internal
temperature.
32
Fact 8
1 out of 4
hamburgers
turns brown
before it has
been cooked
to a safe
internal
temperature.

Which ground beef patty is cooked
to a safe internal temperature?
Source: United States Department of Agriculture/Food Safety & Inspection Service 34
http://www.pueblo.gsa.gov/cic_text/food/therm/researchfs.htm
This IS a safely
cooked hamburger,
(internal temperature
of 160ºF), even
though pink inside.
This is NOT a safely
cooked hamburger.
Though brown
inside, it’s
undercooked.

Research shows
some ground
beef patties look
done at internal
temperatures
as low as 135ºF.
36
37
Cook to 160°F
38
Food thermometers & thin foods
When measuring the
temperature of a thin
food, such as a
hamburger patty, pork
chop, or chicken
breast, an “instantread” digital
thermometer should
be used, if possible.
If using an “instant-read”
dial thermometer, the
probe must be inserted
in the side of the food so
the entire sensing area
(usually 2-3 inches)
is positioned through
the center of the food.
39
Myth 9
Meat and
poultry
should be
washed
before
cooking.
40
Fact 9
Washing is NOT
necessary or
recommended.
41
Washing increases
the danger of crosscontamination,
spreading bacteria
present on the
surface of meat and
poultry to:
 ready-to-eat foods
 kitchen utensils
 counter surfaces.
42
Cooking meat and poultry to the
recommended internal temperature
will make them safe to eat.
43
USDA Recommended Safe

Myth 10
We should
be scared of
eating almost
everything!
45
Fact 10
“... the American food supply continues to
be among the safest in the world.”

Proper food
handling helps
assure food
is safe to eat.

storms, for I'm
