harmful bacteria?
Farm to Table Continuum
• A multi-step journey that food travels before it is
consumed
• Each sector along the farm-to-table continuum plays
a role in ensuring that our nation's food supply is
fresh, of high quality, and safe from hazards. If a
link in this continuum is broken, the safety and
integrity of our nation's food supply can be
threatened
• It is the responsibility of everyone of us to keep the
food supply safe along the farm to table continuum!
Vocabulary
• Bacteria – Single cell, independently-replicating
microorganism. Most are harmless, some
beneficial, but others can cause food borne illness.
• Food Borne Illness – Infection or intoxication
caused by the transfer of microbial or chemical
contaminants (substances that spoil or infect),
from food or drinking water to a human. In most
cases, the contaminants are bacteria, parasites, or
viruses
• Pathogen – Any microorganism that is infectious
or toxigenic and causes disease. Pathogens include
parasites, viruses, and some fungi/yeast and
bacteria
Four C’s of Food Safety
To prevent foodborne illness, follow the 4 Cs:
1.Clean - Wash hands, utensils, and surfaces with hot, soapy water
before and after handling food.
2.Cook - Cook foods to safe internal temperatures. Keep hot foods
hot. Use a food thermometer to check (see Danger Zone4 for safe
internal cooking temperatures for meat, poultry, seafood, eggs, and
leftovers).
3.Combat Cross-Contamination - Separate raw meat, poultry,
and fish/seafood from ready-to-eat foods. Don't cross-contaminate.
4.Chill - Refrigerate foods promptly. Keep cold foods cold.
Young Children
Young children are more
at risk for foodborne
illness because their
immune systems are still
developing
People with Immune Systems
Weakened by Disease or
Medical Treatment
The immune system is the body's natural reaction or response
to "foreign invasion." In healthy people, a properly functioning
immune system readily fights off harmful bacteria and other
pathogens that cause infection. However, the immune systems
of transplant patients and people with certain illnesses, such
as HIV/AIDS, cancer, and diabetes, are often weakened from
the disease process and/or the side effects of some treatments,
making them susceptible to many types of infections — like
those that can be brought on by harmful bacteria that cause
foodborne illness. In addition, diabetes may lead to a slowing
of the rate at which food passes through the stomach and
intestines, allowing harmful foodborne pathogens an
opportunity to multiply.
Older Adults
As people age, their immune system and other
organs become sluggish in recognizing and ridding
the body of harmful bacteria and other pathogens
that cause infections, such as foodborne illness.
Many older adults have also been diagnosed with
one or more chronic conditions, such as diabetes,
arthritis, cancer, or cardiovascular disease, and are
taking at least one medication. The chronic disease
process and/or the side effects of some medications
may also weaken the immune system. In addition,
stomach acid decreases as people get older, and
stomach acid plays an important role in reducing
the number of bacteria in the intestinal tract – and
the risk of illness.
Pregnant Women
Changes during pregnancy alter the
mother's immune system, making
pregnant women more susceptible to
foodborne illness. Harmful bacteria
can also cross the placenta and infect
an unborn baby whose immune
system is under-developed and not
able to fight infection. Foodborne
illness during pregnancy is serious
and can lead to miscarriage,
premature delivery, stillbirth, sickness
or the death of a newborn baby.
