9 Tips for Food Safety When the Grid Goes Down

Recently, 600 million people in India were without power for two days. According to news sources, the suspected cause was one of simple supply and demand: more people wanted power than the Indian infrastructure was able to deliver. It was not only lights out – but lights out for half of the population. Even I have a problem wrapping my brain around a blackout of that magnitude.

It is important to note that in India, for many, electrical power is a luxury, where according to a recent census, one third of the households do not have enough to power even light a single light bulb. Still, when the grid went down so did transportation systems, manufacturing systems, communications systems and of course, household systems.

And what about those household systems? The first thing that may come to mind is air conditioning in a climate where there is 80% humidity in 90 degree Fahrenheit temperatures. Sweltering heat can be uncomfortable, yes, but what about refrigeration? How do you keep food safe when the temperature is 90 and the power grid is down for longer than a few hours?

Keeping Food Safe When the Electricity Goes Out

1. Place appliance thermometers in both the refrigerator and the freezer. After a power outage, check the temperature to determine whether your food is still safe to consume. Safe temperatures are 40°F or lower in the refrigerator, 0°F or lower in the freezer.

2. Try to keep your freezer as full as possible. Fill empty juice or milk jugs with water and keep them in the freezer (unless you need the space for food, of course). If the power grid goes down, you can use these frozen blocks of ice to maintain the cold temperature in your refrigeration and/or to keep the temperature in your freezer colder for a longer period. A full freezer will hold its temperature for about 48 hours but only 24 hours if half-full.

In addition, if there are warnings of a severe storm on the way, freeze additional water in one-quart plastic storage bags. They are small enough to fit in around the food in the refrigerator and freezer to help keep food cold and won’t make a mess when the ice melts.


3. Have a minimum of a week’s supply of ready-to-eat food that does not require cooking or refrigeration after being opened.

4. Do not open the refrigerator and freezer doors unnecessarily. Take out what you need quickly then close the doors and keep them closed. A refrigerator will keep food cold for about four hours if the door is kept closed.

5. Have coolers on hand that can be used to store the refrigerated foods that you think you will need for the short term. Use the frozen jugs of ice from your freezer to keep the food in your cooler cold. This will mitigate having to open and close the refrigerator door unnecessarily.

6. When the power comes back, check the the temperature inside of your refrigerator and freezer. Discard perishable food that has been above 40°F for two hours or more.

7. Check each item separately. Throw out any food that has an unusual odor, color, or texture, or feels warm to the touch. With frozen food, check for ice crystals. The food in your freezer that partially or completely thawed may be safely refrozen if it still contains ice crystals or is 40°F or below.

8. Frozen foods that have been partially defrosted during an outage should be cooked or reheated to a minimum temperature of 160 degrees.

9. When in doubt, dump it. And never, ever taste food to determine whether it is safe to eat.

Food Safety Reference Charts

The following charts (which can also be found at the FoodSafety.gov website, can be used as a guide when determining whether your food is safe to eat following an outage. Note, however that these are best case times and temperatures and no fudging allowed. Furthermore, you need to decide on your own comfort level but in my own household, if the temperature goes above 36-38 degrees F for any period of time – even 30 minutes – out it goes.

The Final Word

Unlike in India, most Western countries have sufficient electricity to supply every household with the power they need to hook up to the grid. On the other hand, only those who purposely live off grid and rely on solar or generator power know how precious this resource is – especially when it comes to food safety and keeping things cold.

The best time to prepare for an off-grid emergency is now, while the power is still on. The low-cost investment in freezer and refrigerator thermometers plus taking the time to store some frozen jugs of water may make the difference between having a full freezer and refrigerator of food or a dumpster full of smelly, spoiled and unsafe food.

*The supercomputers are dependent on mm laser entry into left cerebellum lobe and trying to overide your left cerebrum and left neocortex transmissions(right-side body controls). This left cerebellum laser sends the forwarding information to the nervous system and thought voice with various options for your control.The lasers which enter thru the top right of skull to right cerebrum and right neocortex are thus the main controller of higher thought processing. Therefore locking you in the creative and dreamy side of the mind. While the logical and reasoning side is limited and the computer sends the artificial cognitive model*(thought voice and options). In short, the laser to left cerebellum must be blocked by silk, vcr tape, tin foil, buttons, magnets, copper,copper screen or all. Perps usually stiffen neck on entry to prevent side to side movement. If no blockers are available, the tilting of head to the right messes up all laser entries and controls of right neocortex. By leaning on hand or tilting head this will disrupt download. The other primary key is the access to the hypothalamus which creates all likes and dislikes and therefore controlling effort and quitting points. This is how they control your use of tv remote, buying decisions, driving decisions and work efforts. The nose must be covered and top of skull with metal, tin foil, silk or vcr tape or something to block access to this vital organ. I have effectively restricted these areas before and the perps have gone to nano laser and acupuncture points. You must then cover eyebrows and ears with something or just grow hair over these areas. Hair restricts thermal infrared imaging and the areas appear cool relative to rest of body therefore making it hard to locate precise acupuncture points. For lung and stomach points I wear a leather jacket or vest or shield with an aluminum cookie sheet or copper platter.
