A federal judge has ordered the shutdown of a Brooklyn fish processing plant that has been plagued for years by Listeria.

Judge Roslynn Mauskopf stuck a harpoon in New York City Fish, granting the government’s request for a permanent injunction against the plant located on Chester St. in Brownsville, which distributes smoked salmon, mackerel and herring.

Mauskopf held a bench trial last summer and determined that New York City Fish’s operators had taken insufficient corrective action after federal inspectors found that food had been prepared and packaged under unsanitary condition where it “may be contaminated by filth,” according to papers filed in Brooklyn Federal Court.

Inspectors had conducted six inspections at the plant between 2006 and 2012 when it operated as New York Fish, when the Listeria bacteria was detected. An inspection in February 2013, when the facility was renamed New York City Fish by new ownership, found many of the unsanitary conditions persisted.
