Can ice go bad in the freezer?

Ice can be a contentious issue, with many people blaming ice for becoming sick. Some water may be contaminated before the ice is made, spreading bacteria into any drink the ice is placed. But, can ice go bad in your home domestic freezer, and if so, why does it go bad?

Did you know that ice purchased from a store or made in your own home can harbor bacteria such as Salmonella, E. coli, and, frighteningly, hepatitis A?

This article is going to provide you with the information you need to use ice from your freezer safely and answer frequently asked questions.

Let’s look at the cold hard truth about ice.

Can ice go bad from being in the refrigerator for too long?

Yes, the air in a freezer gets stale. Anything exposed to air in the freezer acquires a stale flavor. If kept in a sealed bag or container with no air, ice cubes can be kept for a few years without discernible flavor change. 

It is imperative that you defrost your freezer regularly. A build-up of frosted ice is part of the reason why contamination of ice for drinks can occur so easily.

When you open a freezer full of frosted ice, some of it inevitably falls onto the ice tray, but the falling frosted ice could have been contaminated with frozen and fresh meats like chicken or pork. The ice could even contain blood products from meat.

The frost in your freezer builds up every time you open the freezer door, and for freezer boxes contained within the fridge, the frost accumulates every time you open the fridge door.

The first is from moisture in the ambient air and from placing warm items in the freezer. There is a period when the freezer needs the temperature to fall again after placing a large piece of meat to freeze.

Every time you defrost your freezer, you should add fresh water to make clean ice fit for your drinks.

Can ice go moldy?

Ice does not go moldy, but that doesn’t mean that the ice is not carrying or has been contaminated with ice mold spores.

Research indicates that illnesses like E. Salmonella and coli are able to survive in the cold and are more than happy to travel on an ice cube to infect a host. The good news is that inorganic surfaces like ice don’t support bacterial and viral growth and reproduction.

Can ice in an automatic ice dispenser refrigerator go bad?

Ice is one of those things you never give a second thought to, and if the ice does taste a little off, it’s easy to assume it’s the ice maker and nothing else.

How often do you clean your ice maker? Maybe you assume the water that enters the ice maker is unadulterated pure water, but even if it were filled with bottled water, this would not be true.

It can be an obvious clue that your ice maker needs to be fixed if your ice has started to taste or smell unpleasant. Many people would presume that this is just an indication that there are issues with their water supply.

But if your ice suddenly appears weird, check your tap water to be sure. If your tap water tastes good, your ice maker probably needs a thorough cleaning or has a problem that needs to be fixed by a professional.

Can bagged ice go bad?

Yes. The risk may be increased if you purchase a bag of ice from a store where the ice has been manufactured in a back room and scooped into generic bags.

Ice is a sort of frozen food. Ice can and will actually degrade. Hence it is susceptible to contamination from bacteria like Salmonella and E. From E. coli to Hepatitis A, and illnesses might occur.

Did you know the FDA or USDA does not regulate ice? There is a self-regulation code called PICQS. It’s a start, but in real terms, bagged ice from the local store could be far worse for you than bagging and sealing your own ice cubes at home.

Can coffee ice cubes go bad?

Yes. Coffee ice cubes have all of the same problems that regular ice cubes can have, contaminated water and then becoming contaminated in a frosty freezer from contaminated ice particles.

In addition to the typical problems occurring with ice cubes.  After the initial freezing, your coffee ice cubes are usable for roughly two weeks. This is due to the fact that, with time, ice cubes of all kinds will sublimate in the freezer. 

Similar to evaporation, sublimation involves the transformation of a solid (in this case, your delectable coffee ice cubes) into a gas.

Your coffee ice cubes will keep longer if you store them in a zippered Ziploc bag and retain their flavor longer without becoming freezer burned.

Can ice packs go bad?

Ice packs typically last for approximately five years before they degrade and need to be discarded.

The term bad for a freezer pack is subjective, and if you think about when the freezer pack has stopped transferring to the cold into the freezer box is bad then it could become bad within a short space of time.

However, a freezer pack should not be transmitting any bacterial load if its key is clean and away from frozen meats like chicken and pork, and indeed fish.

Freezer bags can be washed in detergent and dried before being placed in the freezer to become icy cold and ready for you to make again. Freezer packs are a great way to chill your lunch pack.

How do you keep ice cubes fresh in the freezer?

Whether you use your own ice dispenser or an ice tray or buy ice from the grocery store, you should implement a freezer maintenance regime that could be done every couple of weeks.

Defrosting your freezer can be a chore, but if you do it regularly and do not wait for the ice to build up like an igloo around the edges of the freezer, it is a simple task that can be done within one hour.

Empty the contents of the freezer and switch off the power to the freezer. Leave the doors open. Use a plastic spatula so you do not damage the refrigerant lines. Don’t use a knife or steel spatula if you need to scrape ice.

Placing a fan in front of the freezer will speed up the process, but you may get some water leakage to the floor, so keep a mop handy.

When the freezer is frost-free, wash the freezer and draw with a well-diluted mixture of bleach and water. This will help to kill off the bacteria remaining in the freezer.

Replace the freezer contents and power up the freezer.

When storing ice in the freezer, ditch the ice tray. It’s a recipe for disaster and may be responsible for passing on bacteria, making you sick. If you make your own ice, place the ice cubes in a Ziploc bag and expel as much air from the bag as possible and seal the bag.

This method of storing your ice cubes will keep the ice contaminant free.

Why does my ice taste like freezer f?

The ice may collect odors from items in the freezer. Occasionally, empty metal ice cube trays will exhibit a “freezer smell.” These “odd flavors” may be inconvenient, but they are not harmful. You can sometimes reduce their intensity by regularly cleaning and defrosting your freezer and ice cube trays.

But ice is subject to freezer burn, and once this occurs, it is best to throw the ice and start with a fresh batch to avoid tainted ice flavors in your drinks.

Is ice full of bacteria?

Because ice never gets a second thought, most of you may think to freeze it and forget it until a drink requires some ice cubes. Life is never that simple. Freezing contaminated water does not kill off the bacteria.

It is true that the bacteria are not proliferating and contaminating the foods in the freezer. However, the bacteria are still alive, in a state of suspension, until the temperature warms and it can become active again.

Bacteria such as Listeria,  E-coli, and salmonella can survive in the freezer happily for almost ever, meaning your ice cubes could be a ticking time bomb for food poisoning.

Final thoughts

Bacteria in ice is a problem. Because no one checks for quality and safety, it is easy for ice to be sold that is contaminated and potentially dangerous to your health.

If you have a clean water supply at home, make your own ice and store the ice in Ziploc bags to keep it as fresh as possible.

Only buy ice from a reputable dealer with a history of supplying ice without problems.

Ice may be the forgotten cube in the freezer, but don’t feel it is as innocuous as you once thought. It is a ticking time bomb that could see you in the emergency room.
