Content
• What is personal hygiene?• Why is it important?• How are diseases spread?
Learning objectives
After this lecture participants will be familiar with:• sources of bacterial contamination from people
• how to control the contamination
Personal hygiene
• Means maintaining a clean body and clean clothing
Food handlers
• can carry bacteria that can cause illness in people who eat the food handlers have prepared
Fish handler Fish as food Sick consumer
Personal hygiene
• This is important because dirt and microorganisms present on the skin and on outdoor clothing can be transmitted to the food
• Micro organisms can also be transmitted to the food via cough, colds and wounds
In fact, people are one of the most common source of food contamination
Don´t forget to wash your hands after you have ……………………..
Source of bacterial contamination from persons
• Intestinal waste (faeces) is a major source of bacterial contamination (Salmonella, Shigella and enterococci)• Because of poor personal hygiene, the bacteria found in faeces are
often found in foods
Employee hygiene
• Food can carry several illness• Respiratory disease, e.g. cold, sore throats, pneumonia,
scarlet fever and tuberculosis
• Gastrointestinal disease, e.g., vomiting, diarrhoea, dysentery
• Typhoid fever
• Infectious hepatitis
Droplets are usually formed by sneezing, coughing and talking
(From Fundamental og Microbiology; Frobisher et al.)
How microbes from people contaminate food
• Skin, fingers, fingernails, jewellery, hair, eyes, mouth, nose, throat, lungs,waste (faeces)• Employees may carry a disease-causing microorganisms
even if they do not have symptoms of the illness
• Handwashing is the most important action
1. Wet hands
2. Soap
3. Lather
4. Brush5. Rinse
6. Soap-Lather
7. Rinse
8. Dry withpaper towel
Handwashing - CCP
Hazards:Crosscontaminationfrom humans, dirtycontainers,utensils, packagesand raw food
Recommended handwashing procedure
Effect of handwashing
....touch hair
.....use nail varnish
....finger in the nose
....sneeze on the fish
What is not allowed.......
Microbes on hair
Transmission of infectious micro organisms
indirect airborne
Direct airborne
contact
via hand and objects
dust borne
settles in dust
wafted into air
(From Fundamental og Microbiology; Frobisher et al.)
How to control?
• Protective clothing (hairnet, coats, trouser, aprons, gloves and boots) are used to protect the food and the processing environment against contamination from people.
• Hand washing with soap and water removes more bacteria than quick hand washing. Very important especially after using toilet, blowing their nose, handling anything dirty, handling money or smoking
Boots ????
Ice plant
Ice in bag
