Handwashing Fact Sheet
Bacteria are everywhere. Some of them are useful, many of them are neither good
nor bad, but a few can make us sick. Many bacteria get from place to place by hitchhiking
on people. They can be found in the folds of skin, in our noses and throats, on
our hair, and under our fingernails. We can also pick up bacteria from things we
touch. Bacteria can be transferred to food from dirty hands, dirty aprons, utensils,
food contact surfaces, and equipment. More than 16% of foodborne disease outbreaks
have been traced to poor personal hygiene of people working with food.
People that handle food can keep harmful bacteria out of food by practicing good
personal hygiene. Simple steps like bathing or showering every day before going
to work and wearing a clean uniform or apron can help. Washing hands often and properly
is also very important. You should always wash your hands:
- before you handle food
- after using the bathroom
- after eating or drinking
- after smoking or chewing tobacco
- after handling dirty plates or garbage
- after working with raw foods
- after touching other parts of your body like your nose, mouth, hair, and skin
- after handling dirty utensils, objects, or equipment.
To wash hands properly you should:
- use soap and hot water
- wash for at least 20 seconds
- dry with a single use towel.
Remember that bacteria are tenacious. Proper hand washing will remove many microorganisms,
but some may remain.
