Bill Marler, Attorney
An accomplished personal injury lawyer and national expert in
foodborne illness litigation, William Marler has been a major force in
food safety policy in the United States and abroad.
His law firm is Marler Clark.
Chamberlain Farms owner Tim Chamberlain said he has
been growing melons in southwestern Indiana for 30
years without an outbreak. He does not believe his farm
is the source of the contamination, but he does not
dispute what authorities have said.
First Some Review Understanding the Microworld
“FATTOM” - helps us to remember the
conditions that support bacterial growth
• F = Food
• A = Acidity (pH)
• T = Time: 4 hours or more
• T = Temperature
• O = Oxygen
• M = Moisture (aW)
Bacteria
•
•
•
•
Microscopic single cells
Lots of moisture required
Cause most food illness
Given the right conditions
they can rapidly grow
– Binary Fission
• Some form spores
(pp 2-7)
Give the Right Conditions & Enough Time

Hepatitis A Virus found
in sewage, can be
transmitted by infected
humans
Norovirus is a growing
problem with food and
person to person
transmission
– Viruses (pp 2-16)
• Leading cause of foodborne illness
• Can survive refrigerator and freezer temperatures
• Cannot grow in food, but once eaten, they can
grow inside a person’s intestines.
• Can contaminate both food and water.
• Can be transmitted from person to person, from
people to food and food contact surfaces
• Hepatitis A Virus and Norovirus
Note: A vaccine for Hepatitis A is
available that provides long-term
protection. However the vaccine
must be given before exposure to
the virus. Some states are now
requiring school age children to be
vaccinated for the Hepatitis A
virus.
The virus replicates in the liver and is shed in high concentrations
in feces from 2 weeks before to 1 week after symptoms appear
Infection produces a self-limiting disease that does not result in
chronic infection or chronic liver disease. Initial symptoms are
followed in several days by jaundice (yellowish tint of skin and
eyes).
The bad news is that 10%–15% of patients may experience a
relapse of symptoms up to six months after becoming infected
with the virus.
“Cruise Ship Diarrhea”
“Day Care Diarrhea”
“Community Wide Diarrhea”
Norovirus
• Do not grow and multiply in food
• Spread by hands contaminating food, person
consumes food & the viruses grows inside the body
• Causing numerous cases of foodborne illness
• Hourly handwashing to be recommended
This person’s clean-looking but unwashed
hand is touching a sterile nutrient rich gel.
After 24 hours, these large colonies provide
visible evidence of the microorganisms that
were transferred from the hand to the gel.
Diseases not transmitted
through food
• Hepatitis B / C
• Blood borne
• OSHA requires training for workers who
may be exposed to blood borne pathogens
• HIV (Human Immunodeficiency Virus)
• Tuberculosis (TB)

“Parasite destruction guarantee”, which is accomplished
by ‘freezing and storing seafood at -4°F (-20°C) or below
for 7 days (total time), or freezing at -31°F (-35°C) or
below until solid and storing at -31°F (-35°C) or below for
15 hours, or freezing at -31°F (-35°C) or below until solid
and storing at -4°F (-20°C) or below for 24 hours’ which is
sufficient to kill parasites.

Fungi (Molds and Yeasts)
•
•
•
•
Require less moisture
Can grow in acid pH
Very adaptable
Grow slower than
bacteria
• Molds – multicellular
• Form spores that are
less resistant than
bacterial spores
• Yeasts bud
Basic Characteristics of Mold
• Mold
– Spoils food and sometimes causes illness
– Grows well in acidic food with low water
activity
– Is not destroyed by freezing
– Can produce toxins such as aflatoxins
Basic Characteristics of Yeast
• Yeast
– Can spoil food rapidly
– May produce a smell or taste of
alcohol as it spoils food
– May appear as a pink discoloration
or slime and may bubble
Mold
(pp 2-24)
FDA recommends cutting away
moldy areas in hard cheese - at
least one inch (2.5 centimeters).
Same procedure can be used for
salami, firm fruit and vegetables.
Fungi can infect & grow in various crops,
including peanuts & corn, contaminating them
with mycotoxins.
Production of aflatoxin is a serious concern.
Salem Witch Trails
Some think a fungus (Claviceps purpurea) contaminated
rye bread with a mycotoxin called ergot producing the
symptoms mistaken for witch craft.
