"Sustained, blatant and deliberate"

That's MPI's verdict on dairy company which hid its positive listeria results ... for years.

From 2012 to 2016, Epicurean Dairy staff repeatedly failed to report positive readings - under direct instruction from a manager.

The company's been ordered to pay a fine and court costs totalling nearly 450 thousand dollars.

A former and current employee have also been fined tens of thousands of dollars.
