the cdc estimates approximately one in six americans suffer from food-borne illnesses each year. with so many of us traveling this time of year, food safety should be top of your mind, whether you're headed to a picnic, a barbecue or an all-day sporting event. joy dubois joins us with some safety tips about the kinds of picnics that we'll be going on, taking stuff with us. you say there are some foods that we should just avoid taking out of the house, huh? >> actually no, you just have to be really smart about it

of how we're getting ready to handle our picnic. for instance, first off wash your hands. some people honestly forget to do that. water may not be available so a great thing to have is a pocket-size gel. make sure it's 60% alcohol. that helps kill any germs. also remember to clean your coolers before you pack them because a lot of people forget to clean the coolers and there's unfortunately bacteria that can lay in there, so wipe them out, clean them out. keep food separate. for instance, make sure that the raw meats are separate from anything that's cooked or already prepared like fruits or vegetables. >> what about things that have mayonnaise in them, don't they usually say don't have mayonnaise out of the refrigerator for very long? >> yes. basically what you want to remember is anything that you've already taken out and put out in the open and in, you know, that picnic environment, you have two hours until microbes can start

>> here's the rules that you told us about. keep the food cold. >> correct. >> let's talk about the other things. >> basically you want to keep and clean your produce. one thing to remember with that is also, you know, when you slice that produce, wash it before you do it because actually that blade can act as an inoculator and make that bacteria grow in that produce. so make sure you wash the produce and make sure your utensils are only being used for that produce and use the utensils for raw meat. keep them separate. >> speaking of handling meat and that kind of thing, you brought an interesting board with you that you think is a good thing to take with you. tell us about it. >> basically you can get these at a lot of different home supply shops. what it is, is you want to keep, again, cooked foods separate from raw foods. for the red you can cut up your meat. green i think for vegetables and keeping the produce clean

salads or anything like that. make sure they're clean before you use them and keep that produce separate from the raw food. >> do you suggest using the rubber gloves when you're handling the meat? >> yeah, absolutely. you can use that. again, rubber gloves would be great. these little plastic bags that you find all over the produce aisles, make your raw meat in those plastic bags and separate tm on your coolers. keep one cooler for the clean produce, those type of items and one for raw foods. >> now let's talk a little bit about the leftovers. when you finish your picnic and are taking things back home, lots of time it's good stuff and you don't want to throw it away. >> the rule of thumb is anything that sat out for less than two hours is safe. that time gets cut in half if the temperature is greater than 90 degrees fahrenheit. the danger zone when foods can multiply is between 40 degrees

anything over 90 degrees like what we've been having lately is only going to be good for one hour so you should definitely throw things out unfortunately. >> as long as you keep it in the cooler, take it out and put it right back in. >> absolutely, then you're safe. >> sounds good. i'm ready for a picnic. >> one more thing, don't forget your thermometer. >> for the meat. >> check the temperatures and then you'll know. >> and what should the temperature be? >> greater than 140 or less than 40 degrees fafahrenheit. >> thanks so much, joy. >> thank you. a group of inmates broke out of their cells in a texas jail to save a guard. take a look at the scene here. the inmate noticed the armed guard loses consciousness. they start yelling, break out of their cells and begin banging on the doors for help. it turns out the guard was having a heart attack. other deputies rushed over and called 911. paramedics were able to revive the guard.
