Authorities Urge Proper Cairns Refrigeration to Curb Food Poisoning

"Cairns refrigeration systems for food storage should have a temperature of no more than 5o C (-15o C for freezers), according to Queensland Health. Beyond this range, it only takes two hours for bacteria to multiply. Among other things, consumers must be on alert for deadly salmonella, E. coli 0157, and campylobacter bacteria. These bacteria thrive in temperatures between 5 o C and 60o C. In just one night, a bacteria colony can number by the billions. Extreme cold prevents them from multiplying any further and even kills them in some cases. Extreme heat, as when cooking or reheating the food, can kill the entire colony."

Cairns Air Conditioning Maintenance: A Must Amid Failing Air Quality

"Like conventional filters, active carbon filters eventually need to be replaced even if they can hold more of the dirty stuff due to their large surface area. The rule of thumb is to change regular air filters every 30 to 90 days, depending on whether or not you have pets at home. You may want to wait a bit longer if your air conditioner has an active carbon filter. For the best results, you might want to call upon an air conditioning expert like All About Air to take a closer look at your Cairns air conditioners. Trained technicians can strip units down for a thorough inspection and a more accurate assessment."
