Definition
All measures necessary to ensure the safety, soundness and wholesomeness of foodstuffs and includes preventing contamination by foreign bodies, poisons and harmful or spoilage bacteria.
Characteristics of Food Poisoning
Incubation period: 1 to 72 hours since eating contaminated food
Duration: 1 to 6 days - or longer Symptoms include:
- vomiting- diarrhoea- nausea- abdominal pain
Hospitalisation may be necessary Death is a possibility
Food Poisoning is Caused By
3. Physical Objectives Metals / Nuts / Bolts Nails / Hair Poisonous Plants

What are Micro-organisms?
Benefits Difficulties
Bacteria:
Used to make cheese & yogurts.Helps food digestion
Can spoil foodsCan cause food poisoning
Fungi: Some are poisonous e.g. some species of mushroom
Yeast: Used to make bread and alcoholic beverages
Can make fats ,wine, cider, beers rancid
Moulds: Used as an antibiotic e.g. Penicillin.
Can spoil food - e.g. green mould adds flavour to cheese
Viruses: can cause illness
Bacteria Characteristics
Rod-shaped cells
Clostridium perfringens
Spiral-shaped cells
Campylobacter jejuni
Round cells Staphylococcus
aureus
• Bacteria are almost everywhere:on plants, animals, humans, in the air, in water, in soil• Pathogenic bacteria usually do not change the colour, taste, smell, texture or appearance of food
Bacteria Need Food
MeatPoultryEggsDairy products i.e. perishable food
What term would you give to these foods?
Bacteria grow best on high protein food such as:
Bacteria Need Moisture
Foods such as poultry, meat and dairy products contain water
Bacteria lie dormant in dried food and will regenerate once water is added
Keep moisture away from dry foodstuffs, such as egg powder
Bacteria Need Warmth
The Danger Zone
Ideal temperature for pathogenic bacterial growth: 37°C
Do not store food in the Danger Zone (5°C - 63°C)
A
63°C
5°C
37°C
Bacteria Need Time
In the right conditions, bacteria can divide in two every 20 minutes - In 12 hours, one bacterium can produce 68 thousand million
Prepare food as close to consumption time as possible
Binary Fission
mature cell splits in 2
Most Bacteria Need a Neutral pH
Creating acid or alkaline conditions can disrupt bacterial growth
Most bacteria like a neutral pH

Control of Bacterial Growth
Source top quality food produce Serve hot food hot as soon as possible,
or cool quickly, refrigerate or freeze Maintain the cold chain Thaw frozen food in a fridge or
microwave Reheat food thoroughly (to 70°C or
higher) Wash all raw produce thoroughly
Wash your hands frequently and maintain high standards of personal hygiene
Keep the workplace clean Separate raw food and cooked food during storage
and handling and use separate utensils. Do not allow ill or infected persons to work with
food Follow guidelines of IS 340 & IS 341
Control of Bacterial Growth (Cont.)
Non-Bacterial Food Poisoning
Chemicals- Insecticides- Pesticides- Pollutants
- Natural chemical poisons e.g. mourel mushrooms
Foreign Bodies- Insects - Rodent droppings - Small objects
How Food Poisoning Bacteria Affects The Body
ToxinSome bacteria excrete waste products which are toxic
Rapid poisoning of circulatory system and vital organs
Infectioncaused by pathogensBlood/pus in

resembles a skin infection - but inside the body
Common Bacteria Which Cause Food Poisoning
Salmonella
Staphylococcus aureus
Clostridium perfringens
Bacillus cereus
Escherichia coli
Clostridium botulinum
Salmonella
Reported cases of Salmonellosis are on the increase – 1,000 cases diagnosed in 2007 Common Foods: Chicken, Egg dishes along with
their by products Toxins / Spores: No Incubation period: 12 - 36 hours Symptoms: Diarrhoea, abdominal pain, fever, Control: Thorough cooking of poultry, meat, milk
and eggs. Strict personal hygiene and temperature control. Avoid cross-contamination. Control pests. Use quality assured or pasteurised eggs
Escherichia coli
Foods: Water, mince meats Incubation Period: From 12 - 60
hours Toxins: No Spores: No Duration and type illness: 2 - 9 days Symptoms: Causes watery bloody
diarrhoea, severe dehydration, renal failure and can prove fatal
Control: Good hygiene practices and avoid cross contamination
Food Allergies
A food allergy or hypersensitivity is an abnormal response to a food triggered by the immune system. i.e. the body thinks it has been poisoned and fights back.
2% of all adults have an allergy
Up to 6% of children have allergies
Roughly 4 million Americans alone or 1 million in the UK
What are the symptoms?
Tingling sensation in mouth
Swelling of tongue and throat
Difficulty breathing
Hives
Vomiting
Abdominal cramps
Diarrhoea
Drop in blood pressure
Loss of consciousness
Death

Legislation & the Food Handler
Every person working in a food
handling area shall maintain a
high degree of personal
cleanliness and shall wear
suitable clean protective clothing
a
Personal Hygiene Practices
Coughing/sneezing over food Nail biting Nose picking Finger tasting Spitting Breathing heavily on glasses Failure to wash hands frequently Blowing on freezer bags to open
a
Bad Hygiene Habits
Personal Hygiene Practices
Handle food or the food contact surface as little as possible
Keep fingernails short and clean
Do not wear: Jewellery Nail varnish/False Nails Perfume/aftershave

Personal Hygiene Practices
Hands washed thoroughly and regularly
When are staff expected to wash their hands?
Hand Washing
Wash hands: Before starting work After using the W.C. After handling refuse After using a handkerchief After handling or preparing
raw food Before handling cooked or
ready to eat food After cleaning duties Before putting on disposable
gloves
Hand Washing
Alcohol hand disinfectants are only effective if used on physically clean hands and therefore they should not be used as a method of hand disinfection unless hands have been thoroughly washed.
Hand wash sinks should have Hot and cold water (preferably mixer, elbow,
knee or electronically operated) Non perfumed liquid bactericidal soap Single use paper towels
Hand Washing
Bacteria on hand after touching an old used
dishcloth
Notice how people often miss their thumbs when
washing hands
Hand Washing
Bacteria on hand after using the toilet & not washing the
hand
See how thorough washing of the hands removes most of the
bacteria
Disposable Gloves
Not a substitute for hand washing
Ideal for handling ready to eat foods
Only worn for short periods of time
Must only be used for single operation
Control of Infection
Staff can not be permitted to work in areas where food is exposed if they are suffering from boils, infected wounds, flu, infectious skin disorders on their face, hands or forearms and/or infections of the mouth, throat, nose, ears or eyes.
a
Personal Hygiene Practices Facilities
Dedicated sink Signage with pictures Pre-mixed running water at 55 degrees Anti-bacterial soap Paper towels
Procedures Hands together Hands back to back Fingers Thumbs Fingers to palms Rinse
Illness Reporting
Potential recruits should complete a medical questionnaire
For certain types of illnesses staff may not be allowed to return to work, as a food worker, without clearance from a doctor
a
Protective Clothing for Food Handler
Headgear protecting all hair
Neckerchief
Double-breasted, long-sleeved jacket
Long apron
Protective footwear
All staff working where unpacked food is handled, displayed, or processed must wear clean protective clothing
a
Holding Hot Foods for Service
The general rules for buffet type service are:
Hot high risk food to be ≥ 63°C before placing in heated holding unit
Protect food from cross-contamination Check temperatures every two hours
Hold high risk foods at ambient temperature a maximum of 120 minutes
Corrective action to be taken and recorded
a
Displaying Cold Food
Cold high risk food o °C to 5°C Keep cold food items refrigerated when not on
display
Protect food from cross-contamination
Do not overfill chilled display cabinets and rotate stock regularly
Segregate raw and cooked foods
Prepare sandwiches and fillings as near as possible to the service time
Corrective action to be taken and recorded a
Serving Food
The temperature of chilled food must be within the range of 0°C to 5°C, hot food ≥63°C
For self-service counters, sufficient serving spoons, tongs, cake slices, etc. must be provided at the point of service
Preheated/pre-cooled insulated containers to be used for internal distribution
Serve dishes held at ambient temperatures, such as desserts, within 120 minutes of production
a
7. Cross contamination
Cross-contamination can be defined as:
The direct or indirect transfer of biological, chemical or other contaminants from raw food to other food that may cause the food to be unsafe for human consumption.
Types of Cross contamination
Direct - examples
Contact between raw and cooked food
Coughing and sneezing
Prevention: Separate raw and cooked foods. Comply with personal hygiene practices
Indirect - examples Using the same work surfaces, utensils or equipment for raw and cooked food Wiping surfaces with a contaminated dishcloth Food handlers with contaminated hands preparing food
Prevention: comply with good hygiene practices
