• Preventing contamination is one of the
best measures to fight bacteria.
– But what happens when you contract a
bacterial infection?

 New Area of Focus: Bacteria and your
health.
Copyright © 2010 Ryan P. Murphy

This portion of the unit will begin discussing
the negatives of bacteria / food borne illness.
It’s important to know that bacteria are critical
to our survival and play many important roles
in the ecosystem.

• Why should you care about learning
about food borne illnesses?

• Answer! 76+ million Americans contract a
food borne illness each year.

• Answer! 76+ million Americans contract a
food borne illness each year.
– Learning about them can help you when the
picture below becomes your home for a few
days.

• Bacterial Food Poisoning
– 81 million cases a year.
– 20 of the many thousands of different bacteria
actually are the culprits.
– Symptoms, including
diarrhea, fever, vomiting, abdominal
cramps, and dehydration.
– Salmonella, E.coli.

– Symptoms, including diarrhea, fever, vomiting,
abdominal cramps, and dehydration.

• Bacteria Available Sheet for Class Work

• Activity! A trip to The BAZAAR Café.
• Please record the following.
• BAZAAR Café
– 1.)
– 2.)
– 3.)
– 4.)
– 5.)
– 6.)

– Please select one item from each table and put
a spoonful into your cup and then record that
item on your list.
– Put all six items in your cup (stomach).
– Please use the spoon in each container only
as not to cross contaminate the buffet.
– Once everyone is seated we will test who has
contracted a food borne illness by dipping a
strip of Litmus paper into your cup.
– Green = You contacted a food born illness.

Create a name
/ specific food
item for each
and put on
the card.
Three food
items are
contaminated
with bacteria
(baking soda)
Most cups
filled with just
water, and
three with
water and
baking soda

– Teacher added Baking Soda in a few of the
bowls of water. (Could use NaOH)

– Teacher added Baking Soda in a few of the
bowls of water. (Could use NaOH)
– Litmus Paper can then used to test which
bowl had the Baking Soda / Food Borne
Illness (Could us Phenolphthalein as indicator
for the NaOH)

• Washing food before preparation and
serving.

• This lettuce looks healthy, why should I
wash it?
– It only grows in a field.

• What is one thing missing from this
workplace?

• Answer – A restroom to dispose of waste
and to wash hands.

– Some places are responsible, follow code and
provide facilities to workers. Some do not.

Bathroom

• Where in a restaurant would you expect to
find the most harmful bacteria?

• Answer! Studies have found the lemon /
limes have more harmful bacteria on them
than even the restrooms.

• Answer! Studies have found the lemon /
limes have more harmful bacteria on them
than even the restrooms.
– Very rarely are the lemons washed before
they end up in your drink or on your food.

• Learning proper hygiene and hand
washing.

• Proper hand washing techniques.

• Why do we turn off the faucet with the
paper towel?

• Do you think that this bathroom door
handle is germ free?

• Do you think that this bathroom door
handle is germ free?
-You’ve now washed your hands to just touch
a handle that hundreds have touched.
-Most haven’t washed their hands.

“I’m putting
feces in my
mouth but I
don’t know
it.”

• Activity – How well do you wash?
– Squirt lotion on hand and rub it in until it’s gone.
– Observe under Ultra-violet light.
– Boys wash hands quickly (typical).
– Girls follow guidelines from previous slide.
– Follow up, compare the quick wash vs. long.

 Refrigeration: Prevents the small number of
bacteria from growing rapidly.

 Destroying the bacteria by proper cooking.

• When the wait staff asks how you would
like your meat cooked, say…
• “I would like my meat well done!”

 Avoiding re-contamination.
 Clean cutting board immediately after use.

• Don’t place raw produce on cutting board
and then place something else that isn’t
going to be cooked.

going to be cooked.
– Don’t prepare a salad on a board that has
touched raw meat without cleaning.

“Remember to properly cook your
spaghetti and meatballs to avoid
contamination.”

• Activity Reading with Questions.
– Bacteria and your food.

• Preventing contamination is one of the
best measures to fight bacteria.

 Penicillin: Antibiotic that destroys bacteria
derived from penicillin mold (fungi).

• Penicillin won’t kill a virus, it only attacks
bacteria.

• Treat your wounds, they are an open door
for bacteria.

• One type of infection is cellulitis
(inflammation of the skin caused by bacteria)
.

• Conjunctivitis: What type of bacteria is it?

• A pimple is made up of dead skin, oil, and
lots of bacteria.

• Gangrene: A death of body tissue that
usually occurs when there has been an
interruption of blood supply, followed by
bacterial invasion.

• Seek medical attention immediately.
(Antibiotics)

• This is the treatment option when gangrene
has spread.

• Don’t go swimming with an open cut or
wound.
– It is an entrance for bacteria into your body.

• What type of bacteria is this water bacteria
called vibrio?

• Answer: Staphylobacillus (Coma shaped)

 Antiseptic: Agent that kills or inhibits the
growth of micro-organisms on the
external surfaces of the body.

• Please take a first aid course to learn
proper cleaning of a wound. Cleaning a
wound safely has many steps.

– Includes disinfecting.

– Includes cleaning debris.

– Includes irrigating.

– Includes bandaging.

• The Lesson to be learned.
–Please treat wounds properly.
–Why wouldn’t you?

• Area of Focus: Bacteria and Tooth Decay

• Bacteria in your mouth eat food and
releases lactic acid when they do cellular
respiration. Acid on teeth = Decay.

• This is what can happen if you don’t clean
your teeth and allow them to rot away.

 Plaque is the accumulation of bacteria and
micro-organisms on a tooth.

• Plaque can be defined as a complex
microbial community, with greater than 1010
bacteria per milligram.

– 10,000,000,000 per milligram.

– 10,000,000,000 per milligram.
– That’s roughly 3 billion more than there are
people on Earth in something that weighs about
as much as a grain of rice.

 Tartar is dental plaque that has
mineralized.

 Tartar is dental plaque that has
mineralized.
 Tartar can form when plaque is not removed
from the tooth surface.

• What type of bacteria is seen this picture
of plaque?

• Answer – Maybe a form of bacilli, but 400
distinct bacterial species may be found in
plaque.

• Activity and Video - Flossing our teeth.
– Please watch movie and then floss.
– Movie will play again, use paper towel to wipe
plaque on and dispose of.

brush and smile like the person in the video.

gums that, without treatment, can cause
serious gum problems and disease.
Brushing your gums helps prevent.

• Avoid a diet heavy in sugars, also avoid
drinking acidic drinks as they decay tooth
enamel.

• Use a straw: Sugar + Acid don’t hit tooth
as much.

• Use a straw: Sugar + Acid don’t hit tooth
as much.
– Straws can be a waste of plastic and end up
in the landfill. 

• If you want healthy teeth,

• If you want healthy teeth, don’t smoke.

• If you want healthy teeth, don’t smoke.
– Smoking and chewing cause dental Staining.

• Guess the hidden picture beneath the
boxes.
– Raise your hand when you think you know.
You only get one guess.
