Is Food In The Refrigerator And Freezer Safe To Eat After A Power Failure?

By Leave a Comment

The power is out all over town. Hurricane Irene has downed power lines up and down the East Coast and I’m sure many of you are wondering what to do with all that food in your fridge and freezer.

From numerous past experiences I know that one of the challenges in the aftermath of a power failure is figuring out what to do with the food in the fridge and freezer. 

The Basic Rules For Leftovers

If you cooked up a storm right before the actual storm (or whatever caused the power failure), according to the March 2010 edition of the Nutrition Action Healthletter (Center for Science in the Public Interest), you should follow these general rules:

  • The mantra is:  2 Hours–2 Inches–4 Days
  • 2 Hours from oven to refrigerator: Refrigerate or freeze your leftovers within 2 hours of cooking. Throw them away if they are out longer than that.
  • 2 Inches thick to cool it quick: Store your food at a shallow depth–about 2 inches–to speed chilling.
  • 4 Days in the refrigerator–otherwise freeze it:  use your leftovers that are stored in the fridge within 4 days. The exceptions are stuffing and gravy– which should be used within 2 days. Reheat solid leftovers to 165 degrees F and liquid leftovers to a rolling boil. Toss what you don’t finish.

Food Safety

The following food safety information is from the CDC:

  • If power is out for less than two hours food in the refrigerator and freezer will be safe to eat. While the power is out keep the refrigerator and freezer doors closed as much as possible.  This helps to keep food cold for a longer period of time.
  • The refrigerator will keep food safely cold for about four  hours if it is unopened. A full freezer will hold the temperature for approximately 48 hours (24 hours if it is half full) if the door remains closed.
  • If power is out for longer than 2 hours follow these guidelines:
    • Freezer:  “A freezer that is half full will hold food safely for up to 24 hours. A full freezer will hold food safely for 48 hours. Do not open the freezer door if you can avoid it.”
    • Refrigerator: “Pack milk, other dairy products, meat, fish, eggs, gravy, and spoilable leftovers into a cooler surrounded by ice. Inexpensive Styrofoam coolers are fine for this purpose. Use a food thermometer to check the temperature of your food right before you cook or eat it. Throw away any food that has a temperature of more than 40 degrees Fahrenheit.”

Can Thawed Or Partially Thawed Food In The Freezer Be Frozen Again?

According to the USDA:  “food may be safely refrozen if the food still contains ice crystals or is at 40 °F or below. You will have to evaluate each item separately. Be sure to discard any items in either the freezer or the refrigerator that have come into contact with raw meat juices. Partial thawing and refreezing may reduce the quality of some food, but the food will remain safe to eat. See the attached charts for specific recommendations.”

What If Flood Water Covered Food Stored On Shelves And In Cabinets? 

According to the USDA follow these guidelines for what can be kept or should be thrown out:  “Do not eat any food that may have come into contact with flood water. Discard any food that is not in a waterproof container if there is any chance that it has come into contact with flood water. Food containers that are not waterproof include those with screw-caps, snap lids, pull tops, and crimped caps. Also, discard cardboard juice/milk/baby formula boxes and home canned foods if they have come in contact with flood water, because they cannot be effectively cleaned and sanitized.”

How Long Can Your Thanksgiving Turkey Safely Stay On The Table — And In The Fridge?

How Do Turkeys Cross The Road?

Where I live, I often have to stop my car and wait for the wild turkeys to cross the road.  I’m not kidding.  They start climbing over a stone wall from a wooded area one after another.  Gorgeous, they’re not.   And they don’t cross in a timely fashion, either.  They’re sort of in a line but sometimes one shows an independent streak and turns around to look for the others.  Quite a sight – and, quite annoying when I’m in a hurry having seen this parade many times before – although it makes me smile every time!

These are not the turkeys that most of us will find on our dining room tables – but certainly are distant relatives of those eaten by the early New England settlers.

Turkey Is A Very Good Source Of Lean Protein

Turkey is low in fat and high in protein. A 3 1/2-ounce serving is about the size and thickness of a new deck of cards. The fat and calorie content varies because white meat has less fat and fewer calories than dark meat and skin.

Meat Type (from a whole roasted turkey) Calories Total Fat Protein
Breast with skin 194 8 grams 29 grams
Breast w/o skin 161 4 grams 30 grams
Wing w/skin 238 13 grams 27 grams
Leg w/skin 213 11 grams 28 grams
Dark meat w/skin 232 13 grams 27 grams
Dark meat w/o skin 192 8 grams 28 grams
Skin only 482 44 grams 19 grams

Once Your Bird Is Cooked, Does It Matter How Long You Leave It Out?

Ye, yes, yes! According to the Centers for Disease Control the number of reported cases of food borne illness (food poisoning) increases during the holiday season. You shouldn’t leave food out for more than two hours. To save turkey leftovers, remove the stuffing from the cavity, cut the turkey off the bone, and refrigerate or freeze all leftovers.

The Basic Rules For Leftovers

According to the March 2010 edition of the Nutrition Action Healthletter (Center for Science in the Public Interest):

The mantra is:  2 Hours–2 Inches–4 Days

  • 2 Hours from oven to refrigerator: Refrigerate or freeze your leftovers within 2 hours of cooking. Throw them away if they are out longer than that.
  • 2 Inches thick to cool it quick: Store your food at a shallow depth–about 2 inches–to speed chilling.
  • 4 Days in the refrigerator–otherwise freeze it: Use your leftovers that are stored in the fridge within 4 days. The exceptions are stuffing and gravy  which should be used within 2 days. Reheat solid leftovers to 165 degrees F and liquid leftovers to a rolling boil. Toss what you don’t finish.

How Long Can I Keep Leftover Turkey In The Freezer?

Frozen leftover turkey, stuffing, and gravy should be used within one month. To successfully freeze leftovers package them properly using freezer wrap or freezer containers. Use heavy duty aluminum foil, freezer paper, or freezer bags for best results and don’t leave air space. Squeeze the excess air from freezer bags and fill rigid freezer containers to the top with dry food. Without proper packaging, circulating air in the freezer can create freezer burn – those white dried-out patches on the surface of food that make it tough and tasteless. Leave a one inch head space in containers with liquid and half inch in containers filled with semi-solids.

Happy Thanksgiving

The Five Second Rule: A Bunch of Baloney!

By Leave a Comment

Five second rule in a WikiWorld comic.


Also the three second, eight second, and you name the number rule.  No kidding.

So why is it a bunch of baloney that when you drop a slice of bologna on the floor as you are making a sandwich for lunch, even if you reclaim it right away — certainly in three or five seconds, it still may be crawling with organisms by the time it nestles between slices of bread?

What Is The Five Second Rule?

Although not inscribed in stone, in general terms the five second rule means that if food falls on the floor you can safely eat it if you pick it up within five seconds.  There are a whole bunch of variations having to do with the length of time the food remains on the floor.  I remember one of my son’s college hockey teammates firmly holding to an eight second rule – as he snatched a post-game French fry off of the rink’s snack bar floor.  Have you ever closely looked at the floors in a hockey rink?  Even the seasoned coach turned green.

A Zero Second Rule?

A food scientist and his students at the food science and human nutrition department at Clemson University set out to determine if the rule has some validity or if it’s just a bunch of bunk. Horror of horrors, they found that bacteria are transferred from tabletops and floors to food in five seconds and that the five second rule doesn’t apply when it comes to eating food that has fallen on the floor.

Making a strong case for a zero second rule, they found that salmonella and other bacteria can live up to four weeks on dry surfaces and that they are immediately transferred to food.

Location, Location:  The Sidewalk Is Better Than The Kitchen Floor

Their findings are in conflict with previous research by Connecticut College students who scattered apple slices and Skittles on the dining hall and snack bar floors and let them reside there for five, 10, 30, and 60 seconds. The apple slices picked up bacteria after one minute and nearly five minutes scooted by before the Skittles became contaminated.

Most researchers agree the important thing is not how long food takes a vacation on the floor, but where that stay is. Believe it or not, according to a professor of microbiology and pediatric infectious diseases at the University of Colorado School of Medicine and author of Germ Proof Your Kids, it may be okay to brush off and give back the gummed up bagel that your kid tossed out of the stroller. Pavement has fewer types of germs that cause illnesses than the kitchen floor which is probably laden with health hazardous bacteria from uncooked meat and chicken juices.

SocialDieter Tip:

A universally applied five second rule for dropped food is bogus.  Food can get contaminated with health hazardous bacteria very quickly.  There is some dropped food wiggle room depending mostly on where the dropped food lands.  Amazingly, food dropped outside, as long as it has dropped on pavement or blacktop rather than on the soil in a chicken coop or an animal pasture, is generally safer than food dumped on your kitchen floor.

And, FYI:

  • 100 billion: bacteria in our mouths
  • 100 trillion: bacteria in our gastrointestinal tracts
  • 2.5 billion: bacteria found in one gram of garden soil
  • 7.2 billion: germs in the average kitchen sponge
  • 25,000: germs per square inch on an office telephone
  • 49: germs per square inch on a toilet seat

Handle Food Carefully – Or Run A Big Risk

How You Handle Food Really Matters

Here’s a great big reason why paying attention to how you handle food is so important:

Just give ‘em  (bacteria) the conditions they like:  warmth, moisture, and nutrients, and boy will they grow.   A single bacterium that divides every half hour can result in 17 million offspring in 12 hours.

Putting food in the refrigerator or freezer will stop most bacteria from growing —  except for Listeria (found in lunch meats, hot dogs, and unpasteurized soft cheese), and Yersinia enterocolitica (found in undercooked pork and unpasteurized milk).  Both will grow at refrigerator temperatures. Cooking food to a temperature of 160 F will kill E. coli O157:H7. Don’t let that container of take out food hang around on the counter, either. Put it in the fridge and heat it up when you’re ready.

Safety Tips

  • Cut produce, like half a watermelon or bagged salad, should be refrigerated or surrounded by ice – don’t buy it if its not
  • Separate your raw meat, poultry, and seafood from the other food in your shopping cart and in your refrigerator – packages do leak
  • Store perishable fresh fruit and vegetables (like berries, lettuce, herbs, and mushrooms) in a clean refrigerator at a temperature of 40F or below
  • Wash your hands for 20 seconds with soap and warm water after you prepare any food
  • Wash fruit and vegetables under running water just before eating, cutting, or cooking, even if you plan to peel them. Don’t use soap (it leaves a residue). Produce washes are okay, but not necessary.
  • Scrub firm produce like melons and cucumbers with a clean produce brush and then let air dry.
  • Toss the outer leaves of heads of leafy vegetables like cabbage and lettuce.
  • Thoroughly cook sprouts. Children, elderly people, pregnant women, and people with a weakened immune system should avoid raw sprouts.
  • Drink pasteurized milk, juice, or cider.
  • Lower your pesticide exposure by 90% by avoiding the dirty dozen: peaches, apples, sweet bell peppers, celery, nectarines, strawberries, cherries, lettuce, imported grapes, carrots, and pears. Think about buying organic for the dirty dozen and conventional for the foods with the lowest levels of pesticides:  onions, avocados, sweet corn, pineapple, mango, asparagus, sweet peas, kiwi, cabbage, eggplant, papaya, watermelon, broccoli, tomatoes, and sweet potatoes (Environmental Working Group).
  • Eat locally grown food:  food is well traveled – the average mouthful has a 1400 mile journey from farm to plate. Locally raised food is fresher, closer to ripe when picked, requires less energy to get to you, and is not as likely to be treated with pesticides after harvest.
  • Wash all produce well before eating – be careful with nibbling the unwashed grapes or berries in the market or on the way home.

When do you toss the leftover Pad Thai (or lasagna) that’s in the fridge?

By 2 Comments

You Are Hungry!

You’re standing in front of your open refrigerator. A container here and a container there. Move them around. Wow. A Tupperware all the way in the back. Wonder what’s in it.

Take a peek. Container #1: the leftover take-out Pad Thai from five days ago. Container #2: the rest of your lasagna you brought home last night from a huge restaurant portion. Some of Mom’s really delicious stuffing from last weekend. That’s in the Tupperware.

Big question: Will you end up writhing in pain and spending the next day in the bathroom if you eat any of it?

How Long Can Food Stay Out?

According to the FDA, when you buy hot, cooked food, you should eat it right away and avoid letting it sit out at room temperature. If the food is cold, eat it within two hours of preparing it, store it in the fridge, or freeze it.

Buzz, Buzz: The Food Is Here

When food is delivered, you want to prevent any lurking potentially nasty and harmful bacteria from multiplying, so eat the food within two hours after it arrives. If you aren’t going to eat it within two hours keep it hot in an oven set at or above 200° F (93° C). Side dishes, like that delicious stuffing in the Tupperware, also have to be kept hot in the oven. Cover the food to keep it moist while you’re keeping it warm. Don’t guess at the temperature of the food. Use a food thermometer to check that the food is kept at an internal temperature of 140° F (60° C).

The Danger Zone

The FDA defines the “danger zone” as the range of temperatures at which bacteria can grow. It is usually between 40° and 140° F (4° and 60° C). To keep food safe, it’s important to keep it below or above the “danger zone.”

The 2 Hour Rule

There is a 2 Hour Rule: Throw away any perishable food (the kind that can spoil or become contaminated by bacteria if left unrefrigerated) that has bee left out at room temperature for more than two hours. When the environmental temperature is above 90° F (32° C), throw out the food after one hour.

The Center for Science in the Public Interest’s Nutrition Action Healthletter, expands on the Rules For Leftovers with what they call:

2 hours – 2 inches – 4 days

Think:

2 hours from oven to refrigerator: any leftovers should be

refrigerated or frozen within 2 hours of cooking or they should be thrown away.

2 Inches thick to cool it quick: food should be stored in containers at a shallow depth of about 2 inches or less, to speed the chilling time.

4 days in the refrigerator or freeze it: use refrigerated leftovers within 4 days with the exception of stuffing and gravy which should be used within 2 days. Reheat Solid leftovers should be reheated to 165 degrees F and liquid leftovers to a rolling boil. Whatever you don’t finish, throw out.

Do you still want that Pad Thai? Maybe some lasagna?
