The “five-second rule” states that if food falls on the floor, it’s still good to eat if you pick it up within five seconds. The “rule,” however, has been debunked.
   
Some people jocularly state that the rule has been extended to 10 seconds. “RT @misskimiya: With the recession, the ‘5 second rule’ has been extended to 10 seconds” was posted on Twitter by Alexander Spit on March 5, 2011. “@kfc_colonel If you drop the chicken, the 5-second rule has been extended to 10 seconds.  #Couchgating” was posted on Twitter by Kristine Photo on January 25, 2013. “Due to the government shutdown and ever increasing price of food, the 5 second rule Has been extended to 10 seconds. Keep calm and carry on” was posted on Twitter by twapel on October 5, 2013. “Due to the government shutdown & ever increasing price of food. The 5 second rule has been extended to 10 seconds” was posted on Twitter by Kari Macedo on October 18, 2013.
     
“Due to the economic crisis and ever increasing price of food, the 5 second drop rule has now been increased to 10” (shown on an image) was posted on Facebook by Mary Alice Levy Landau on November 6, 2021. “Due to inflation and food price increases, the 5 second rule has been extended to 10 seconds” was posted on Twitter by Joel Fischer on November 13, 2021.
   
     
Wikipedia: Five-second rule
The five-second rule, sometimes extended to the ten-second rule, is a food hygiene myth that states a defined time window where it is safe to pick up food (or sometimes cutlery) after it has been dropped and thus exposed to contamination.
