Vegetables – How long to keep defrosted vegetables in the fridge

My answer to the other question still applies: vacuum packing will not prevent most foodborne pathogens from multiplying. In the case of chicken, it will stop campylobacter (which needs small amounts of oxygen) but will not stop salmonella or listeria.

Here's how you can determine if thawed, previously frozen chicken is still safe to eat:

• When freezing, marking the freezing date on masking tape and stick it on the package
• When thawing, mark the thawing date similarly
• To determine if it's still good: subtract the freezing date from the original expiration date, and see if it's been that many days since you thawed it

This method works because spoilage is halted by freezing... but not reversed. Once you thaw, the process picks back up where it left off. A few days in the fridge after thawing should be fine, assuming you don't wait until right before expiration to freeze the chicken.

I have always made sure that I only defrost enough to meet the needs of the moment for sushi. If you cut the blocks into 4 to 8 rolls worth, they should defrost under running water in just fifteen to twenty minutes, just about the time it takes me to do a batch of sushi rice. That said, fish once defrosted will start to lose flavor immediately but will remain edible for 2 days. Once it starts to smell, get rid of it immediately, and I would play it very safe on that "starts to smell" the faintest whiff should be enough to send it to the bin.
