tuna safety and extending its shelf life after sterilization the cans are rapidly cooled to a safe temperature this helps retain the tuna's quality and prevents any further cooking that could affect the product's texture and taste once cooled the cans are labeled with essential information such as the product's name expiration date nutritional content and branding the cans are then carefully packed into cartons or Boxes for shipping and distribution throughout the entire production process strict quality control measures are in place to ensure that the canned tuna meets industry standards and regulatory requirements samples are regularly taken for
