Yeast infects grape juice and converts the sugar into a toxin, ethanol, that in large quantities causes people to act goofy. Lactobacillus acidophilus infests milk, converting it into yogurt and eventually resulting in a pestilence of health food advertising. :D

 

If you move this to homework help, you might get examples your teacher won't give you a funny look for.

Can anyone give me good 2 examples of food infection (with microbe name, how the microbe becomes present in the food, and the mechanism by which it causes disease {if possible} ;))

 

I'm asking about food infection THAT IS HARMFUL TO HUMANS

Campylobacter is a bacterial pathogen that causes fever, diarrhea, and abdominal cramps. It is the most commonly identified bacterial cause of diarrheal illness in the world. These bacteria live in the intestines of healthy birds, and most raw poultry meat has Campylobacter on it. Eating undercooked chicken, or other food that has been contaminated with juices dripping from raw chicken is the most frequent source of this infection.

 

E. coli is a bacterial pathogen that has a reservoir in cattle and other similar animals. Human illness typically follows consumption of food or water that has been contaminated with microscopic amounts of cow feces. The illness it causes is often a severe and bloody diarrhea and painful abdominal cramps, without much fever. In 3% to 5% of cases, a complication called hemolytic uremic syndrome (HUS) can occur several weeks after the initial symptoms. This severe complication includes temporary anemia, profuse bleeding, and kidney failure.

 

Clostridium botulinum- This organism produces a toxin which causes botulism, a life-threatening illness that can prevent the breathing muscles from moving air in and out of the lungs. Sources: improperly prepared home-canned foods; honey should not be fed to children less than 12 months old.

 

those are a couple. btw, it sounds more scientific if you call them foodborne illnesses.

Aspergillus produces aflatoxin's a deadly carcinogen that is believed to enter the body, go though the cell and is broken down into deadly metabolites that can cause mutations. Aspergillus grows on moldy peanuts and corn. You can also look at tapeworm and other worm pseudopod parasites in food.
