What Is Super Frozen Tuna?
Did you know 80-90% of the tuna sashimi in the US is treated with carbon monoxide before you ingest it?
This unsafe method is completely banned in Japan, all of Europe, Canada, Taiwan and China. This is a method companies use to preserve color and disguise the age of the product - and fool you, the consumer.
At Fish for Sushi, we pride ourselves in doing the exact opposite by providing the best sashimi available. You can rest assured that none of our Tuna is ever carbon monoxide treated. Instead, our Tuna is Super Frozen.

> Step 2: Once the Tuna is caught, it is quickly gilled and gutted.
> Step 3: The Tuna is then then immediately put into the super freezers, freezing to a core ultra low temperature (ULT) of -76ºF, the Eutectic Point or EP.
> Step 4: The entire process is complete between 10 and 20 hours out of the water.
