From the very beginning, every generation that’s passed through Unión Salazonera Isleña has taken responsibility for preserving and growing the legacy we’ve received.

1973 – USISA is founded.

A key date in our history, when the reorganisation of Isla Cristina’s main salting industries was completed and the company’s incorporation was made official.

1980 – Acquisition of the TEJERO brand.

1990 – Opening of branches in Valencia and Barcelona.

We increased our presence throughout the country, strengthening our relationship with customers and showing greater proximity and responsiveness to demand.
