3. Introduction
Food is the basic necessity of man. It is a mixture of different nutrients such
as carbohydrate, protein, fat, vitamins and minerals. These nutrients are
essential for growth, development, and maintenance of good health
throughout life.
Food poisoning is an illness caused by eating contaminated food. It's not
usually serious and most people get better within a few days without
treatment. In most cases of food poisoning, the food is contaminated by
bacteria, such as salmonella or Escherichia coli (E. coli), or a virus, such as
the norovirus.

6. Causes of Food Poisoning
Food poisoning occurs when contaminated food or water is ingested. Contamination can
occur anywhere along the process of obtaining and eating food – it can occur during growing,
harvesting, processing, storing, or preparation stages. In most cases, bacteria, viruses, or
parasites are transferred to food from other sources, making these organisms the most
common causes of food poisoning.
The following table shows some of the possible contaminants of Food Poisoning:
Contaminant Onset of symptoms Foods affected and
means of transmission
Campylobacter 2 to 5 days Meat and poultry.
Contamination occurs
during processing if animal
feces contact meat surfaces.
Other sources include
unpasteurized milk and
contaminated water.

7. Causes of Food Poisoning
Contaminant Onset of
symptoms
Foods affected and means of
transmission
Clostridium botulinum 12 to 72 hours Home-canned foods with low acidity,
smoked or salted fish, baked in aluminum
foil and other foods kept at warm
temperatures for too long.
Escherichia coli (E. coli) 1 to 8 days Spread mainly by undercooked ground
beef. Other sources include
unpasteurized milk and contaminated
water.
Salmonella 1 to 3 days Raw or contaminated meat, milk, or egg
yolks. Can be spread by knives, cutting
surfaces or an infected food handler.
Rotavirus 1 to 3 days Raw, ready-to-eat produce. Can be
spread by an infected food handler.

8. Risk Factors of Food Poisoning in
Bangladesh
Food poisoning can occur in any age group or population, but a number of factors
increase the risk of developing the disease. Not all people with risk factors will get food
poisoning. The top five risk factors that most often are responsible for foodborne illness
outbreaks are:
• Improper holding temperatures of potentially hazardous food
• Improper cooking temperatures of food
• Dirty and/or contaminated utensils and equipment
• Poor employee health and hygiene
• Food from unsafe sources.

9. Risk Factors of Food Poisoning in
Bangladesh
 Improper holding temperatures of potentially hazardous food
Cold foods shall maintain ≤41°F and hot foods shall maintain ≥135°F. If foods stay
in between those temperatures for any period, ensure they are time and temperature
controlled and documented. Time and temperature control for safety (TCS) foods
must be date marked and stored no longer than 7 days. Remember, first day of
preparation or when a food package is opened, counts as day 1. When in doubt,
throw it out!
 Improper Cooking Temperatures of food
The Food and Drug Administration has established minimum internal cooking
temperatures for foods to ensure pathogen counts are reduced to safe levels. Ensure
metal stem thermometers are conveniently stored and accessible for employees to
monitor final cooking temperatures.

10. Risk Factors of Food Poisoning in
Bangladesh
 Contaminated Equipment/Cross-Contamination
Cross contamination can occur from a variety of sources, including chemical and
raw foods. To prevent the spread of harmful pathogens, all equipment and utensils
shall be properly cleaned and sanitized at least once every 4 hours. Ensure sanitizer
solutions are monitored using their appropriate test strips. Low sanitizer
concentrations will fail in effectively removing pathogens from surfaces, while
high concentrations will leave a toxic residue.
 Food from Unsafe Sources
All foods distributed in licensed food establishments must be obtained from
approved sources that comply with applicable laws and regulations. All food shall
be inspected upon delivery to ensure proper temperatures, it’s condition and overall
sanitation.

11. Risk Factors of Food Poisoning in
Bangladesh
 Poor Personal Hygiene
Poor personal hygiene practices serve as the leading cause of foodborne
illnesses. Food establishments must promote a culture of food safety by
developing an employee illness policy, proper handwashing procedure,
and a no barehand contact policy with ready to eat foods.
