Typhoid, Viral hepatitis, strepto and
staphylococcal infections.
PREVENTION:
• The first essential is to have complete medical examination
carried out of all food handlers at the time of employment.
• Any person with the history of typhoid fever, diphtheria,
chronic dysentery ,tuberculosis should not be employed .
• Person with wounds or skin infections should not be permitted
to handle food or utensils.
• Education of food handlers in matters of personal hygiene ,
food handling, utensils, dish washing is the best means of
promoting food hygiene.

immediately after visiting a lavatory. Finger nails should be
trimmed and free from dirt.

Ill effects of bad hygiene
• Food poisoning:
• Reason: Food poisoning is the outcome of having stale food or rotten food.
• Effects: Food poisoning leads to vomiting at times spitting out blood, loose motions, extreme sweating, choking of the wind pipe, extreme stomach ache etc.
• Acidity:
• Reason: Having food that has too much oil.
• Effects: It is a burning sensation in the gut
and in the chest at times. It can further lead
to peptic ulcers and mouth ulcers if not
treated. This raises the stomach pH and
gives a restless and burning sensation.
• Stomach disturbance:
• Reason: Having street food that is highly
adulterated and unbalanced.
• Effects: People having these foods are
often found complaining about stomach
upsets or constipation.
• Asthma:
• Asthma is a disease affecting the airways that carry air
to and from your lungs. People who suffer from this
chronic condition (long-lasting or recurrent) are said to
be asthmatic.
• Reason: Asthma has been found to be in higher
abundance in Kitchens where there are cockroach
infestations.
• Effects: The inside walls of an asthmatic's airways are
swollen or inflamed. This swelling or inflammation
makes the airways extremely sensitive to irritations and
increases your susceptibility to an allergic reaction.
• Halitosis:
• Halitosis, popularly known as bad breath, is a disease of
the mouth that causes foul breath. In this condition,
unpleasant odor comes out of the mouth of the patient.
• Reason: Certain foods, adverse health conditions and
unhygienic habits are the main causes of bad breath.
• Effects:
