As Australian Food Safety Week approaches from November 8 to 15, 2025, a startling revelation has emerged: 66% of Australians have experienced food poisoning or gastro, yet over half mistakenly blame the last meal they ate. This eye-opening statistic, revealed by the Food Safety Information Council’s national survey, underscores the urgent need to debunk widespread myths about food safety. But here’s where it gets controversial: could the culprit behind your illness be something you ate weeks, or even months ago? Lydia Buchtmann, the Council’s CEO, emphasizes that this year’s campaign is all about shattering these misconceptions.
‘Many believe food poisoning stems from the last thing they ate, but the reality is far more complex,’ Ms. Buchtmann explains. Historically, health authorities relied on memory-based interviews to trace the source of illnesses, a method prone to inaccuracies. But this is the part most people miss: modern technology has revolutionized how we identify outbreaks. Social media posts now flag potential issues in real time, while whole genome sequencing can pinpoint the unique DNA of pathogens—viruses, bacteria, fungi, and parasites—linking them to specific food sources. If the same DNA is found in both the food and the affected individuals, the contaminated product can be swiftly removed from shelves.
During Australian Food Safety Week, the Council will tackle several other persistent myths. Here’s a sneak peek at what they’ll address:
- Hand sanitiser vs. handwashing: While sanitiser is convenient, it’s ineffective against certain pathogens, like the highly contagious Norovirus. Only thorough handwashing with soap and water, followed by drying with a clean towel, ensures safety.
- The ‘5-second rule’: Bacteria don’t wait politely before contaminating dropped food. Floors are breeding grounds for germs from shoes, pets, and daily activities—always err on the side of caution.
- ‘Best before’ dates: These indicate quality, not safety. Food can be consumed after this date, but always heed the ‘use by’ date to avoid risks.
- Rare hamburgers: Minced meat, including hamburgers and sausages, must reach an internal temperature of 75°C to eliminate bacteria that spread during processing.
- Smell and taste tests: Food poisoning often comes from meals that look and smell perfectly fine. Bacteria thrive in the ‘danger zone’ (5°C to 65°C) without altering flavor or appearance.
- Mouldy food: Even a small amount of mould can produce mycotoxins, harmful substances that accumulate over time and pose serious health risks.
But here’s a thought-provoking question: With advancements in technology, why do so many food safety myths persist? Is it a lack of awareness, or are we simply too complacent about our eating habits? Ms. Buchtmann encourages everyone to test their knowledge with the Food Safety Myth Quiz available on the Council’s website, www.foodsafety.asn.au. Do you think you’re a food safety expert?
