LERS began as a personal culinary endeavor in 1969, when Fely Pelaez learned to prepare delicious smoked country ham in her home at Del Monte, Bukidnon. That year, family members and friends bought her ham for Noche Buena (Christmas dinner).

The ham eventually became popular. So, what started out as a small hobby became a cottage industry, and later a family corporation, selling also in Cagayan de Oro, and now in Manila. Despite its growth, SLERS continues to make fine quality foods the traditional way. SLERS products have a reputation for making special occasions even more special, and making any day a holiday.

Aside from producing quality foods, SLERS is also involved in food education. It is leading the industry in adopting food safety and quality assurance procedures in the Philippines. It is the first to provide the public with seminars and workshops to encourage personnel hygiene and safe food preparation.

The brand name SLERS is an acronym of the names of Fely's children.
