New rules mandate freeze for raw fish in NYC

The next sushi roll or ceviche dish you order in New York City will likely have been frozen before it hits your plate.

New rules set by the City Health Department require that all fish served raw or under-cooked be frozen first to guard against parasites.

The new guidelines go into effect next month. The change is not expected to make a major impact.

Restaurant industry leaders say most chefs already freeze their fish to guard against bacteria and parasites.
