The first Portuguese unit of canned sardines was established in Setúbal, in 1880.

During the first half of the XX century the canning industry was forced to expand, thanks to its subsidiarity in assisting the war industry. During the period corresponding to World War II, Portugal became the main world producer of canned sardines, consolidating the quality and the importance of its products.
