Food and water-borne diseases could be caused by toxins produced by flourishing bacteria; injurious algal species; or polluted food and/or water with some kind of bacteria, parasites or viruses. Many incidents of food poisoning occur when someone eats food with harmful bacteria in it. The toxins or bacteria produced by them can make a person sick. Bacteria could also enter into the water supply and cause someone to fall sick.
1. Spreading of food- or water-borne bacteria
Food and water-borne diseases do not spread through casual contact with any affected person. A person can contract food and waterborne bacteria basically by eating or drinking food items that contained the bacteria in it.

Generally food- and water-borne infections cause diarrhea, vomiting, nausea, stomach cramps and fever. However each bacterium causes specific symptoms like:
Salmonella: Fever, bloody diarrhea, headache and lack of energy.
Shigella: Mucus or blood in the stool.
E.coli: Diarrhea with blood and some people gets affected with hemolytic uremic syndromes that results in the damage of RBCs and kidney problems.
C. parvum: stomach pain and watery diarrhea.
Cholera: Acute diarrhea, leg cramps and vomiting.

Intake of plenty of fluids and medicine such as acetaminophen or ibuprofen to control fever and pain are the treatments one can do at home. But if the person is seriously ill he must consult a doctor.
