A microbiologist tested the popular 'five-second rule' by placing food on the floor for varying time intervals and observing microbial growth in petri dishes. Despite public belief, all samples showed bacteria growth, indicating that no time on the floor is safe for food. The experiment became popular on TikTok, gaining significant attention and revealing that even food placed on the floor for zero seconds was contaminated. This finding highlights misconceptions about food safety and encourages people to be mindful of hygiene.
"Looks like even 0 seconds is too long," declared the scientist while holding up the corresponding petri dish, which was freckled with white bacterial spots.
Every sample had evidence of microbial growth, proving that no amount of floor time is safe when it comes to contamination.
Aicher concluded that whether the food is left for 'five seconds or 60, it'll be nasty either way.'
