Bacteria

Basic Microbiology Food Poisoning & Food Borne Disease

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)

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 Oxygen

Most bacteria are aerobic i.e. they need air

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

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

THE LAW

Legal obligation not to contaminate food

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

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.

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

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
