FOOD HAZARDS
Biological Hazards: Viruses
• Viruses are even smaller than bacteria. They consist of genetic
material surrounded by a protein layer.
• Unlike bacteria, they can’t reproduce or multiply unless they are
inside a living cell, but they can be carried on almost any surface and
can survive for days or even months.
Biological Hazards: Viruses
• Viruses are inactive or dormant until they enter a living cell. Then
they use that cell to make more viruses and release them into the
organism. The new viruses can then enter new cells and continue to
multiply.
• Because viruses do not multiply in food like bacteria, food-borne viral
diseases are usually caused by contamination from people, food
contact surfaces, or, in the case of seafood, contaminated water.
Biological Hazards: Viruses
Virus
Virus: Hepatitis A
Cause/Characteristics:
• This is a severe disease that can last for
many months.
Biological Hazards: Viruses
Virus: Hepatitis A
Source of Contamination:
• contaminated water or ice, shellfish from polluted waters, raw fruits
and vegetables, milk and milk products, infected food workers
Foods Usually Involved:
• shellfish eaten raw, any food contaminated by an infected person
Biological Hazards: Viruses
Virus: Hepatitis A
Prevention:
• Practice good health and hygiene. Use only certified shellfish from
safe waters.
Biological Hazards: Viruses
Virus
Virus: Norwalk Virus Gastroenteritis
Cause/Characteristics:
• This disease affects the digestive tract,
causing nausea, vomiting, stomach
cramps, diarrhea, and fever.
Biological Hazards: Viruses
Virus: Norwalk Virus Gastroenteritis
Source of Contamination:
• human intestinal tract, contaminated water
Foods Usually Involved:
• water, shellfish from polluted waters, raw vegetables and fruits
Biological Hazards: Viruses
Virus: Norwalk Virus Gastroenteritis
Prevention:
• Practice good health and hygiene. • Use only
certified shellfish from safe waters. • Use
sanitary, chlorinated water.
• Cook foods to safe Internal temperatures.
Biological Hazards: Viruses
Virus
Virus: Rotovirus Gastroenteritis
Cause/Characteristics:
• The symptoms of this disease are vomiting
and diarrhea, abdominal pain, and mild
fever. Around the world, rotovirus
infections are the leading cause of
digestive disease in infants and children.
The illness lasts from 4 to 8 days.
Biological Hazards: Viruses
Virus: Rotovirus Gastroenteritis
Source of Contamination:
• human intestinal tract, contaminated water
Foods Usually Involved:
• water and ice, raw and cold prepared foods, such as salads
Biological Hazards: Viruses
Virus: Rotovirus Gastroenteritis
Prevention:
• Practice good health and hygiene. • Use
sanitary, chlorinated water. • Cook foods
to safe Internal temperatures.
Biological Hazards: Parasites
• Parasites are organisms that can survive only by living on or inside
another organism. The organism a parasite lives in and takes
nourishment from is called the host.
• Parasites may pass from one host organism to another and complete a
different stage of their life cycle in each organism. Human parasites are
generally transmitted to them from animal hosts.
Biological Hazards: Parasites
• Human parasites are usually very small, and although they may be
microscopic, they are larger than bacteria. They can usually be killed
by proper cooking or by freezing.
Biological Hazards: Parasites
Examples:
• Tape Worm (Undercooked Meat)
• Hook Worm (Contaminated Soil)
Biological Hazards: Fungi
• Molds and yeasts are examples of fungi. These organisms are
associated primarily with food spoilage rather than food-borne
disease.
• Most molds and yeasts, even those that cause spoilage, are not
dangerous to most human beings. Some, in fact, are beneficial, and
are responsible for the veining in blue cheese and the fermentation of
bread dough, for example.
Biological Hazards: Fungi
• Some molds, however, produce toxins that can cause allergic
reactions and severe disease in those people who are susceptible.
• For example, certain molds produce a toxin called aflatoxin in such
foods as peanuts and other nuts, corn, cottonseed, and milk. This
toxin can cause serious liver disease in some people.
Physical Hazards
• Physical contamination is contamination of food with objects that
may not be toxic but may cause injury or discomfort.
• Proper food handling is necessary to avoid physical contamination.
• Examples of physical contamination:
• Glass shards from broken container
• Hair
• Soil
• Stones
Chemical Hazards
• Are toxic substances that may occur naturally or may be added during
the processing of food.
• Examples include agricultural chemicals such as pesticides, fertilizers
and antibiotics. Cleaning compounds and heavy metal (lead and
mercury) are also included.
Chemical Hazards
Preventing Chemical Contaminants:
• Teach employees how to use chemicals
• Store chemicals in original containers to prevent accidental misuse, as
well as leakage into food
• Make sure labels are clearly identify chemical contents of chemical
containers
• Always chemical according to chemical recommendation
Chemical Hazards
Preventing Chemical Contaminants:
• Always test sanitizing solution
• Wash hands thoroughly after working with chemicals
• Wash foods in cold running water
• Monitor pest control operator and make sure chemicals do not
contaminate foods
Chemical Hazards
The following toxins (except lead) create symptoms that show
themselves very quickly, usually within 30 minutes of eating poisoned
food. To prevent these diseases, do not use the materials that cause
them.
1. Antimony
2. Cadmium
3. Cyanide
4. Lead
5. Copper
6. Zinc
Allergens
• Substance that causes an allergic reaction. Reactions to food may
occur as soon as the food is eaten or, in some cases, merely touched;
they also may not occur until hours after the food is eaten.
• Common symptoms of allergic reaction to foods include:
• Itching
• Rash or hives
• Shortness of breath
• Tightness in the throat
• Swelling of the eyes and face
Allergens
• In severe cases, allergic reactions may lead to unconsciousness or
death.
• Allergens affect only some people; these people are said to be allergic
to that specific substance.
Allergens
Foods to which some people are allergic include:
• Wheat products
• Soy products
• Peanuts
• Tree nuts
• Eggs
• Milk and dairy products
• Fish
• Shellfish
Allergens
Non-biological allergens include food additives such
as: • Nitrites (used in cured meats)
• Monosodium Glutamate (MSG, often used in Asian foods)
Allergens in Food Service
Food-service personnel and dining room staff must be well informed of
the ingredients in all menu items and be able to inform customers as
needed
• If any staff member does not know, when asked by a customer, if a
food contains an allergen, the employee should:
• Consult someone who does know
• Urge the customer to order a different item
Avoiding Cross-Contact
• Cross-contact happens when one food comes into contact with
another food and their proteins mix. As a result, each food then
contains small amounts of the other food. These amounts are so
small that they usually can’t be seen.
Cross-Contact vs Cross-Contamination
• Cross-contamination is a common factor in the cause of foodborne
illness. Microorganisms such as bacteria and viruses from different
sources can contaminate foods during preparation and storage.
Proper cooking of the contaminated food in most cases will reduce
or eliminate the chances of a foodborne illness.
Cross-Contact vs Cross-Contamination
• Cross-contact occurs when an allergen is inadvertently transferred
from a food containing an allergen to a food that does not contain the
allergen. Cooking does not reduce or eliminate the chances of a
person with a food allergy having a reaction to the food eaten.
Examples of Cross-Contact
Tips to Avoid Cross-Contact
• Use utensils, cutting boards and pans that have been thoroughly
washed with soap and water. Consider using separate utensils and
dishes for making and serving safe foods. Some families choose a
different color to identify the safe kitchen tools.
• If you are making several foods, cook the allergy-safe foods first.
• Keep the safe foods covered and away from other foods that may
splatter.
• If you make a mistake, you can’t just remove an allergen from a meal.
Even a small amount of cross-contact makes a food unsafe.
Tips to Avoid Cross-Contact
• Wash your hands with soap and water before touching anything else
if you have handled a food allergen. Soap and water or commercial
wipes will remove a food allergen. Sanitizing gels or water alone will
not remove an allergen.
• Scrub down counters and tables with soap and water after making
meals.
