Seattle, Washington-based Loki Fish Company has initiated a recall for one of its smoked keta salmon products over listeria concerns.

The 4-ounce Keta Salmon Lox item was distributed through Cherry Sprout Produce in Portland, Oregon and Central Co-op and Pacific Coast Harvest in Seattle. It was also sold at the University District and West Seattle Farmers Markets in Washington.

No illnesses have been reported to date.

The possibility of contamination was discovered during the FDA inspection at the company's co-packer Felix Custom Smoking, of Monroe, Washington, in July. Loki submitted samples of the Keta Lox to Micro-Chem Laboratories for testing.

Loki has ceased production, sales and distribution of keta lox immediately, it said. It will continue the investigation as to what caused the problem.
