BIOLOGICAL CONTAMINANTS
e.Coli, hepatitis A, and cholera
INTRODUCTION!
Water! It is one of our most important resources, We drink
it, we bathe in it, we play in it, we even use it to produce
electricity. But sometimes run off, sewage, and umm ahem
“waste” can get into water supplies. When this happens
something GROWS inside the water we all use. Something
HORRIBLE SOMETHING TERRIBLE! SOMETHING THAT
KILLS THOUSANDS EVERY YEAR! THESE MONSTERS
ARE CALLED……. Diseases.
E.COLI THE SHELLFISH MONSTER!
T
his monster lives inside our very own bodies! Most e.coli live
inside our intestines and cause no harm to the human it lives in.
SOME E.COLI HOWEVER HAVE GONE…… BAD.
T
HESE E.COLI cause severe abdominal pains , bloody diarrhea ,
S
EVERE VOMITING!
E
.coli can be contracted from eating contaminated
shellfish and raw meat. IT CAN ALSO BE FOUND IN
WATER WHICH HAS BEEN EXPOSED TO “WASTE”.
IT CAN TRAVEL FROM ONE PERSON TO THE NEXT
BY THE VERY TOUCH OF A HAND!
HEPATITIS A, THE LIVER EATER
This monster can cause liver failure, muscle pains, fevers,
and ghastly yellowing of skin and eyes. It is found in food
and water touched by “waste” of someone who has become
infected. If you’re lucky, then the symptoms will pass in 2-3
months. There are 80,000 cases of infections caused by
hepatitis A, although this monster does not kill most of it’s
victims, it does cause extreme pain.
