Food Borne Diseases-Intoxication, Bacterial, Viral And Parasitic Diseases

Food Intoxication:
Food intoxication means the addition of toxic material in food.
Food intoxication may be;
1. Due to Naturally Occurring Toxins in Some Foods;
for example;

• Lathyrism ( caused by the presence of beta oxalyl amino-alanine in food)
• Endemic ascitis ( caused by the presence of Pyrrolizidine alkaloids in food) 

2. Due to Toxins Produced By Certain Bacteria.

For example

• Botulism 
• Staphylococcus Toxins

3. Due to Toxins Produced by Certain Fungi.

Certain fungi grow on food, produce toxins. The toxins produced by fungi are;

• Aflatoxin
• Ergot
• Fusarium toxin

4. Foodborne chemical poisoning. 

• Heavy metal poisoning. For example, mercury (found if fish) cadmium ( fish shells) and lead ( found in canned food.
• Oils Petroleum derivatives and solvents present in foods ( for example mixing of motor oil in vegetable oil.
• Asbestos Poisoning 
• Pesticide residues (DDT, BHC etc) in foods especially in vegetables and fruits.

Food-Borne Infections.

1. Bacterial Diseases;

For example;

• Typhoid fever
• Paratyphoid fever
• Cholera
• B. Cereus food poisoning
• Brucellosis
• Salmonellosis
• Clostridium perfringens food poisoning
• E. coli diarrhoea
• Staphylococcal intoxication
• Streptococcal infections
• Shigellosis 
• V. parahaemolyticus infection.

2. Viral Infections 

For example;

• Hepatitis A
• Viral Gastroenteritis

3. Parasitic Infections

• Taeniasis
• Echinococcus granulosus Hydatidosis
• Trichinosis
• Ascariasis
• Amoebiasis
• Oxyuriasis
