Tuna fish packaged in cans is common in many countries, including Mexico. Canning allows people to preserve food that would otherwise rot or decay.

  • On June 3, 1841, Nicolas Appert was buried in Massy, France. Appert is remembered as the “Father of Canning.” He invented an effective method of preserving food in airtight cans and jars, so they will not spoil. Appert wrote a book describing his method of boiling filled jars sealed with cork and wax. Storing food in airtight metal cans quickly followed. Because of the hard work of people like Nicolas Appert, explorers and researchers can safely participate in expeditions to extreme climates where a food supply may not always be available.


    Appert's invention, along with refrigeration, is responsible for the diets we all now enjoy. Foods in jars and cans are shipped from all across the world to your local grocery store. We now can eat foods that are not locally grown or produced, or foods that are not in season.
