Allergies
Allergies
are reactions of the immune
system to unwanted substances.
Allergens, once ingested, cause the body to produce an excess amount of
histamines which can result in many types of symptoms.
Main symptoms are
vomiting, diarrhea, nausea and throat itchiness and swelling. Milder
symptoms could include sneezing, runny nose, watery eyes, fatigue,
hives, coughing, tightness in the chest, difficulty breathing and
headaches. In severe cases, death may occur.
Examples of substances that can cause an allergic reaction are peanuts,
eggs and seafood. Products of these substances or food prepared with
them can be just as harmful to some people.
Some
food additives, like MSG (flavor enhancer) and sulphites (used to keep fruit and
vegetables looking fresh), can also cause a food intolerance with
similar symptoms.

Bacteria
grow best in
the temperature range between 4ºC and 60ºC. Temperature below
4ºC, and temperature between 60ºC and 74ºC, will not
kill bacteria, but it will not allow them to multiply enough times to
cause an illness. In order to kill pathogenic bacteria you need
temperatures above 74ºC. Temperature is the easiest factor to
control in order to prevent bacterial growth.
