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

Human Parasites, Types of Parasites, and Classification

Parasite: A parasite is a living organism which gets nutrition and protection from another organism where it lives. Parasites enter into the human body through mouth, skin and genitalia. In this article, we will generally discuss the types and classification of parasites. It is important from an academic point of view. Those parasites are harmful, which derives their nutrition and other benefits from the host and host get nothing in return but suffers from some injury. Types of Parasites Ecto-parasite: An ectoparasite lives outside on the surface of the body of the host. Endo-parasite: An endo-parasite lives inside the body of the host, it lives in the blood, tissues, body cavities, digestive tract or other organs. Temporary parasite: A temporary parasite visits its host for a short period of time. Permanent parasite: Permanent parasite lives its whole life in the host. Facultative parasite: A facultative parasite can live both independently and dependently. It lives in the

How to taper off, wean off beta blocker, atenolol, Propranolol, Metoprolol

People usually take atenolol, propranolol or metoprolol for many years as a treatment of high blood pressure or after having an episode of heart attack . Sometimes, it becomes necessary to withdraw these beta blockers due to their potential side effects that trouble the patients or sometimes doctor wants to change the drug and shift the patient to some other anti-hypertensive medicine. No matter whatever the cause is, whenever, a patient who has been using a beta blocker for a long period of time, and he needs to be stopped from further usage of that beta blocker, must not stop taking it. One should taper off the dose of a beta blocker. Now a question arises how to wean off or taper off a beta blocker? The method of tapering off beta blocker varies from individual to individual.
