The following observations can help us determine whether the food inside a sealed can is infected with microbes:

  • A bulging can or lid or a broken seal
  • A can or lid that shows signs of corrosion
  • Food that has oozed or seeped under the jar’s lid
  • Gas formation indicated by tiny bubbles moving upward in the jar or bubbles visible when you open the can
  • Food that looks mushy, moldy or cloudy
  • Food that gives off an unpleasant odour when you open the jar
  • Spurting liquid from the can or jar when you open it
