It’s not all bad news, thankfully — tuna and shellfish are okay.
The New York Department of Health and Mental hygiene just announced new regulations that will require restaurants to freeze many types of fish for a minimum of 15 hours before serving them raw, to kill off bacteria. The Board of Health approved these regulations in March, and they will go into effect next month. Presumably, these new rules were change how a lot of restaurants — especially sushi bars and any places serving crudo or ceviche — store and prepare their fish. It will no doubt also inspire some major menu changes throughout the city, especially at the pricey fish restaurants.
As the Times points out, many high-end restaurants freeze their best fish as a safety precaution. Sushi Zen vice president Yuta Suzuki tells the paper: “We purposely deep-freeze at negative 83 degrees, and we use one of those medical cryogenic freezers.” The amount of time the fish should be frozen to meet the code depends on the temperature and the storage method. The NYT notes that shellfish, fresh-water fish, and “certain types of tuna” are exempt from the rule. And James Versocki, a rep for the National Restaurant Association, tells CBS: “Most grade sushi that restaurants serve are not impacted by this…You know your yellow and bluefin and tuna, they’re allowed to be served raw because they don’t generally have these parasites in them.”
