For how we live.
The reheating is not the hazard. Cooked rice left to cool slowly at room temperature is, because a spore-forming bacterium can build a heat-stable toxin that a second heating will not undo.
Two laboratory studies that dropped food onto contaminated surfaces found bacteria transfer within a second. How much moves depends far more on the food and the surface than on the count of five.
It takes only a handful of viral particles to infect you, it shrugs off alcohol hand gel, and it survives on surfaces for days. That biology explains why the effective defences are the unglamorous ones.
An interim report in NEJM Evidence links the parasitic outbreak to iceberg lettuce and one restaurant chain, with cases spread across most of the state.
The first national estimate of temperature-attributable food poisoning in Australia. A companion study in Queensland tested whether heat also drives drug resistance in the same bug — and found nothing.
