Hi Friend, you may get an email from friends, family or co-workers about an alert from John Hopkins University about Dioxins and plastic containers.  I went to John Hopkins and found it to be a hoax.  The link below is from the John Hopkins website and below that is the text (or similar) to the one that might be emailed to you.  Please inform anyone you care about.

this is the email in question:

Cancer News from John Hopkins

No plastics in micro
No water bottles in freezer.
No plastic wrap in micro 
 
Johns Hopkins has recently sent this out in their newsletters worth noting. This information is being circulated at Walter Reed Army  Medical Center. 
Dioxin Carcinogens cause cancer, especially breast cancer.
Don't freeze  your plastic water bottles with water as this also releases dioxins in the  plastic.
Dr. Edward Fujimoto from Castle hospital was on a TV program explaining  this health hazard. (He is the manager of the Wellness Program at the  hospital.) He was talking about dioxins and how bad they are for us. He said that we
should not be heating our food in the microwave using plastic containers. This applies to foods that contain fat. He said that the combination of  fat, high heat and plastics releases dioxins into the food and ultimately  into the cells of the body. Dioxins are carcinogens and highly toxic to the cells of our bodies.
Instead, he recommends using glass, Corning Ware, or ceramic containers for heating food. You get the same results, without  the dioxins.  So such things as TV dinners, instant ramen and soups, etc.,  should be removed from the container and heated in something else. Paper isn't bad but you don't know what is in the paper. It's just safer to use
tempered glass, Corning Ware, etc. He said we might remember when some of  the fast food restaurants moved away from the foam containers to paper. 
 
The dioxin  problem is one of the reasons. To add to this, Saran wrap placed over foods as they are nuked, with the
high heat, actually drips poisonous toxins into the food, use paper towels.   Pass this on to your family & friends & those that are important in you  life. Life is not measured by the number of breaths we take, but the moments
that take our breath away. Have an amazing day!
