Indoor Temperatures Hit 40°C… Room Temperature Storage Loses Meaning

There are foods with labels that say "store at room temperature" on the packaging. Does that mean it is okay to leave them anywhere in the house?

Experts say caution is needed during sustained heatwaves like the ones we are seeing recently.

Storing at room temperature means keeping indoors, but it does not mean they can be stored at any temperature.

The food industry generally uses around 15°C to 25°C (59°F to 77°F) or 15°C to 30°C (59°F to 86°F) as a reference range for normal temperatures.

This is because indoor temperatures in homes are frequently exceeding 40°C (104°F) amid the ongoing heatwaves.

Measurements showing indoor temperatures soaring to 45°C to 49°C (113°F to 120°F) on strong, sunlit balconies or in homes with air conditioning turned off are frequently reported.

At such high temperatures, caution is required as it can accelerate not only microbial growth and fat rancidity, but also cause changes in color and flavor.

Even within the same house, a cool, well-ventilated pantry or cupboard away from direct sunlight is suitable, and refrigerating them is also an option.
