High Liner Foods has implemented a raft of new health and safety protocols in the wake of the closure of its processing facility in Portsmouth, New Hampshire last month.

The facility, which closed April 20 after several employees tested positive for Covid-19, reopened April 27, after an intensive cleaning and detailed "contact tracing" of all employees infected with the Covid-19 virus, and a detailed assessment of how to mitigate or avoid future outbreaks, High Liner Vice President of Investor Relations and Communications Heather Keeler-Hurshman told IntraFish.
