Given a paragraph about cooking, and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_Q:`.

CONTEXT: There's always the delight of botulism, which thrives in the anaerobic environment provided by vacuum packing. Listeria and vibrio bacteria can grow in an anaerobic environment, and are potential food safety risks present in fish. With this in mind, I would not expect vacuum packing to extend the life of a fish much. It will reduce freezer burn though!  <sep>  Q: How long can I keep thawed vacuum-packed fish in the fridge?
No

CONTEXT: I use two types of cutting boards: wood and [soft] plastic. The plastic is for meat, or anything that could ruin a wood cutting board. Wood is for everything else. If you can afford it, try to get an end-grain wood cutting board.Bamboo is a popular choice right now (it's affordable and sustainable), but I don't have any personal experience with it.Most other materials, especially glass, will ruin your knives.  <sep>  Q: Cutting boards: What are some general tips on purchasing and using a cutting board? A: I use two types of cutting boards: wood and [soft] plastic  <sep> FOLLOWUP_Q: Which one is better for food safety?
Yes

CONTEXT: I suspect it depends what kind of cheese the whey came from. Whey has all of the water soluble components of the milk. It loses the casein and fat. How much of the albumin and lactose it loses depends on the cheese. If the milk was heated enough (190F I believe) then the albumin will denature and not be in the whey. If the cheese was acidified with a bacterial inoculation then the bacteria will have converted some of the lactose into lactic acid which will both be in the whey. Riboflavin is water soluble and is what gives the whey that greenish tint.Either way- most of the nutrients that bacteria like are not in the whey and it is always highly acidic. I have personally kept whey for a couple weeks with no ill effect.I usually use my whey soon by making ricotta. If the cheese it came from didn't denature the albumin in the milk then you can gently heat the whey until the the albumin precipitates out. A gallon of whole milk makes almost a pound of mozzarella and then a little less than a cup of ricotta. That's a lasagna right there.  <sep>  Q: What is the storage life for whey?

Yes
