detect out the FDA recommendation for a fridge ’s temperature , plus how to accurately mensurate it .
A electric refrigerator is one of the most crucial kitchen appliance forfood preservation . keep the correct fridge temperature can prevent or limit the growth of harmful bacterium , proceed food for thought fresh and safe to eat for lengthy menstruum .
" The ‘ temperature danger zone ’ for food is between 40 ° F and 140 ° farad . If foods remain within this chain for an protracted period of time , pathogens that cause foodborne sickness get to multiply speedily , " states Mitzi Baum , CEO of Stop Foodborne Illness .

Frank Baum says you ca n’t see , taste , or smell the bacteria that cause harmful foodborne illness . “ If left out of refrigeration for long than two hours , nutrient becomes a breeding flat coat for harmful bacteria like Staphylococcus aureus and Clostridium botulinum , which can cause serious illness , especially in immunocompromised individuals , " add Baum .
To concentrate the endangerment of nutrient poisoning while preserving the quality of your solid food , you ask to keep your fridge cooled to the recommended temperature . Here is everything you need to know about FDA good word and peak for measure and adjusting your electric refrigerator ’s temperature .
What Temperature Should a Refrigerator Be? FDA Recommendation
" It is recommended by the FDA to keep your fridge at or below 40 ° F to keep your perishable food sweet and out of the temperature danger geographical zone , " says Certified Food Scientist and Certified Culinary ScientistJessica Gavin .
Bad bacterium grow quick between 40 ° F and 140 ° F ( the temperature danger zone ) , replicate in number in as little as 20 minutes . " If you leave food for thought out too long at way temperature , harmful bacterium such as Staphylococcus aureus , Salmonella Enteritidis , Escherichia coli O157 : H7 , and Campylobacter can grow to serious levels that can make foodborne malady , " she says .
TheFDA guidelinesseek to preserve food ’s nutritionary value and timbre , as well as forestall unwellness .
Fridge Manufacturer Temperature Recommendation
While each manufacturer and model offers different guidance , most manufacturers suggest a electric refrigerator temperature between 35 ° and 38 ° F to keep food for thought moth-eaten and fresh for a long prison term without freezing . They also urge a Deepfreeze temporary worker of 0 ° F to keep intellectual nourishment good frozen .
Other Fridge Temp Considerations
There are other considerations to keep in mind , such as the temperature of the milieu and humidity level , to ensure that your refrigerator maintain the ideal temperature .
Like most house appliances reliant on electricity , fridges typically work better in cooler environment . Suppose you localise a refrigerator in a warm way or near heat sources , such as an oven or radiator . Under those conditions , the components work harder and expel heating . To maintain the idealistic temps , the electric refrigerator may be under a considerable amount of strain , decreasing overall energy efficiency . In such scenarios , set the fridge temperature to a couple of degrees cooler than advocate to counteract the external heat .
inner humidity level also count . High humidness levelscan get extravagant moisture , mold growth , and spoiling . On the other hand , low humidness levels dry out out foods — leading to wilting , shrinkage , and trim down shelf life history . A dehumidifier and right breathing are essential for preserving the freshness and quality of food .
Some electric refrigerator come with adjustable humidness control that allow you to manage the levels in unlike sections to fit the ideals for different types of intellectual nourishment — especially separating wise garden truck from cooked food .
Another way to verify humidity is to forefend couch blistering dishes in the electric refrigerator . Also , fend off possible action and closing the refrigerator frequently or leaving the electric refrigerator doors open longer than necessary .
How to Measure a Fridge’s Temperature
Not all electric refrigerator temperature standard of measurement are exact or well-heeled to find ; sometimes , they ’re very far back on the top shelf . It is common for fridges to be a few degree off the mark on the configurations . More puzzling still , some electric refrigerator models do n’t display the temperature at all and instead just temperature levels of 1 – 5 , with 5 being the cold . roll in the hay how these levels read into actual level can be dispute without a thermometer .
To accurately measure a fridge ’s temperature , it is good to use a thermometer . you could easily buy a freestanding thermometer online or at a local store . Place it in the fridge and leave it for 20 minute before contain the recital , then line up the fridge temperature accordingly . Besides a standard room thermometer , the FDA website reads , “ Appliance thermometer are the best mode of have a go at it these temperatures and are generally inexpensive . ”
If you detect fluctuating temperatures after adjusting the controls , consult the merchandise manual of arms to belittle user error . Inspect the fridgeseals for damage and replace them if needed . Seals see to it that the fridge keeps coolheaded air in and quick melodic line out .
