Define Biological Hazards

Among the biological hazards the major concern  is from microorganisms. Few of the microbiological hazards. Biological hazards, ,  include bacterial, fungal, viral and parasitic organisms (protozoa and worms)  and/or  their toxins. There  are  many microorganisms, which  are pathogenic  to humans, but relatively  few are associated with  foods.These microorganisms that  cause diseases  are  termed  as  food-borne  pathogens'.  There are three types of food-borne disease  from microbial  pathogens  infections, intoxications  and  toxic.

Infections are  result from the ingestion of live pathogenic organisms which multiply within thy  body  and produce disease. While intoxications occur when  toxins produced  by pathogens are  ingested. You must  remember that  intoxications can occur even  if no viable microorganisms  are ingested. Can you suggest how this is possible? Well, this often  occurs when foods  are stored under  conditions which  allow the pathogens  to grow and produce  toxin.  It is interesting to note  that  subsequent processing of food may  destroy  the microorganisms but  not the toxin.
