                Mold and Yeast


                     Mold  and  yeast  are  types  of  fungi.  Unlike  bacteria  and


              viruses,  once mold and yeast begin to grow they are visible to the

              naked  eye.  Molds  spoil  food,  causing  discoloration  and  an

              unpleasant smell and  taste.


                Parasites


                      Parasites  are  small  organisms  that  live  in  a  host  organism

              such  as  cattle,  swine  or  fish  and  can  also  cause  foodborne  illness.


              Proper  cooking  can  kill  parasites.  As  Amebiasis  (Entamoeba

              histolytica  infection),  Ascariasis  (Intestinal  roundworm  infection),

              Toxoplasmosis (Toxoplasma  infection)



               II.   Chemical hazards:


                      To  be  nutritious  and  safe,  food  must  be  free  not  only  of

              microbiological  hazards  but  also  from  synthetic  and  natural


              chemical  contaminants.  Naturally  present  chemicals,  chemicals

              produced  by  cooking,  (environmental)  contaminants,  additives,

              cleaning  chemicals.  Food  adulteration  and  the  use  of  pesticides,

              hormones, antibiotics and other man-made  chemicals.



              III. Physical hazards : foreign objects can get into food , e.g.


                  bone, rock, metal from:



                    Air


                    Dust
