Thermos Food Safety Tips

According to the CDC, one out of every six Americans gets sick from eating contaminated foods or beverages. Most of these cases are preventable though if people would just take a few moments to handle their food safely and adhere to some basic sanitation guidelines. And this is an area where a thermos can prove quite handy because it can be used to keep foods or beverages at a stable temperature.

However, that doesn’t mean the user shouldn’t do their due diligence first. When packing food or beverages in a thermos for a day at the park or to take to work, the user should first pay attention to basic food preparation and storage guidelines, follow the instruction from the company that makes the thermos and know what foods can and can’t be stored in a thermos. With that in mind, we’ve included some basic guidelines to get the user started.

Buy a Safe Thermos

While most of the name brand thermoses are BPA and phthalates-free, it never hurts to check, especially when buying an off-brand thermos. Consumers should check that the thermos conforms to Consumer Product Safety Commission (CPSC) guidelines, or the Consumer Product Safety Improvement Act (CPSIA).

Read the Thermos Instructions

While I technically covered this subject in the paragraph before the last section, it’s an important enough point that I feel like it needs repeating. Before using any thermos, it’s important to read and understand all of the instructions that came with it. The instructions will tell the user how to prepare the thermos for first-time use, how it should be cleaned and sometimes, it will even tell the user what kinds of foods can be stored in it.

Check the Thermos Rating

Another thing to pay attention to is how long a particular thermos can keep a particular food or beverage hot. Some models can only keep an item hot for 6-hours, while others may keep food hot for 12-hours or longer. The consumer also should realize that hot and cold temperatures may differ on the same thermos. For example, a thermos might keep an item hot for 8-hours but will keep an item cold for 24-hours, or vice-versa. The user should never try to store food or beverages longer than the manufacturer recommends.

Hand Wash the Thermos

Sure, most thermoses which are manufactured today can be washed in a dishwasher, but I feel that hand washing does a better job at removing food residue in the thermos. That’s because some dishwasher solutions contain bleaches which can pit stainless-steel and give bacteria a hiding place. Hand washing the thermos will also extend the life of the product for this very same reason.

Make Sure All Surfaces are Clean

It’s also important that not only is the thermos clean but that anything that touches the thermos is clean. This includes the cutting board where the food may be prepared and the user’s hands. All cooking utensils should also be clean, and fruits and vegetables should be rinsed under running water before they’re packed.

Pack Foods According to Temperature

An important consideration for anyone using a thermos for packing their food during the day is to ensure they pack according to the temperature of the food. And that’s just a fancy way of saying that hot foods should be packed hot and cold foods should be packed cold. If a particular food item is intended to be a hot food, then make sure that it’s at least 165-degrees Fahrenheit when it’s packed. If the food is intended to be a cold food item, then make sure it’s 39-degrees or colder when it’s packed. That ensures that the foods are kept out of the food danger zone, a temperature range where bacteria can multiply rapidly. The danger zone is between 40-degrees and 140-degrees.

Priming the Thermos

A trick that can be used to make the thermos even more effective in keeping hot foods hot and cold foods cold is priming the thermos. This is done by preheating or pre-cooling the thermos. A person can do this by simply storing hot or cold water in the thermos for a few minutes. After this time has passed, the hot or cold water is then dumped out, and food or beverages can then be added to the thermos. This preheating or cooling is a great way to get the most of the thermos.

Store Foods with Liquids

Unless the thermos is going to only be used for storing foods for extremely short periods of time, then foods that don’t contain liquids as a base shouldn’t be stored in it. That’s because thermoses are designed to work with liquids and not with solid foods. Solids stored in a thermos won’t be safe to eat in a couple of hours, so if the user needs to store their lunch longer than that, then they should choose the appropriate thermos safe food items. These liquid-based food items include soups, stews, and beverages. That doesn’t mean the thermos can never be used for solid food items, it just means they shouldn’t be stored for longer than 2-hours at a time.

Pack Before Leaving the Home

Obviously, if the user packs the item right before they head out the door, then it will remain hot or colder longer. I’ve seen people pack their food items and then leave the thermos on the counter for an hour, and that’s extra time the thermos could have kept the item cold outside the home. If food is packed right before leaving, it gives the user that extra buffer where they know they’ll food remain temperature stable.

Be Careful Packing Foods for Children

If the thermos is being used to pack food for a child’s lunch, then it’s very important that it won’t be so hot that it will burn the child when they open it. While it’s important to keep the food at a safe temperature, it shouldn’t be so hot that it can scald the child.
