Imagine you have to create a well balanced meal for yourself and three friends. how can you make sure that the food you serve them will not contain foodborne illnesses?

You can make sure that the food being served does not contain foodborne illnesses (food poisoning) by getting organic foods and knowing where they came from. For example, you can get grown foods from someone you know (and trust very well) or grow your own food, such as vegetables. But make sure to routinely check and tend to the crops if you are planting them on your own.

Another way to be sure food does not contain foodborne illnesses is to avoid purchasing pre-packaged meats. There is a possibility of the meat containing parasites. To be safe, cook meat at least 140 degrees to kill parasites.

While cooking, make sure to cook the food thoroughly and that it is not rotten. Cook the soon-to-be-served food completely. Also, if you are using anything such as milk, check it's expiration date ahead of time.

i think it's the first one because doctors aren't the ones who get rid of the old needles. most of them time it's not even doctors who give you shots, it's nurses.
