Quick Summary

According to Salim Hourieh, founder and CEO of ItsGlo Cleaning, it's recommended to deep clean a fridge every four to six months, with the ideal frequency being once every quarter for regular users who dispose of expired items promptly. A study by the University of Veterinary Medicine in Vienna found that only 38% of household fridges operated below the recommended temperature threshold, but even at optimal temperatures, uncleaned fridges had significantly higher amounts of food-associated bacteria. The researchers concluded that simple measures like regular cleaning have a significant impact on microbiological safety. Health Canada advises keeping raw meat and other foods stored properly to prevent foodborne illnesses.

Story summary

Evelyne Selberherr, a researcher from the University of Veterinary Medicine in Vienna, Austria, studied 45 household fridges and found that only 38% operated below the recommended temperature threshold of 5C, while 24% exceeded 7C, which is considered an unfavorable worst-case scenario for food safety. This study highlights the importance of proper fridge maintenance to prevent foodborne illnesses. Meanwhile, Salim Hourieh, founder and CEO of ItsGlo Cleaning in Toronto, recommends deep cleaning a fridge every 4-6 months, in addition to routine cleaning, as long as it is used regularly and expired items are disposed of properly.
