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.

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.

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.
