Magnified Meat

There are lots of microorganisms that feed and grow on meat. When you see flies buzzing around your kitchen, you should make sure your meat is covered up!

Maggots

Flies like to lay their eggs on meat, and you probably won’t notice them because they are so tiny. When the eggs hatch, the maggots that come out will start eating the meat. They do this by squirting their saliva on the meat to soften it. Then they suck up the meaty liquid.

Parasites

Organisms that live on or in other living things are called parasites. Some microanimals are parasites that live in people’s bodies. The meat we eat may contain microscopic parasite eggs. When you eat meat containing live eggs or larvae, a parasite can hatch, mature, and make its home inside your intestine.



Maggots start out tiny, but they are easy to see after they have been feeding and growing for a few days.
