I'm just starting my research into a potential Cuba trip for next February, so please bear with me if any of my questions are ill-informed. And before going further, I'll acknowledge that the food shortage's and rationing's impact is much more significant for Cubans themselves than for tourists, and that they relate to significant political debates about Cuban, U.S. and other countries' policies.

Having said all that, before news of the food shortage and rationing broke, my wife and I and two friends had just been starting to plan a short trip of about five days to Havana for next February, conceivably including a day or overnight trip out of town. (Can't do longer because of work schedules, but it could well be a precursor to a longer visit down the line.) We would not be going to a resort. We'd just stay in a casa and dine at local restaurants.

I realize things could well change, given how far off our possible trip would be. But I'd still welcome any folks thoughts on the following:

1. Most fundamentally, if things don't change much re the food (and perhaps fuel) situation, what should we expect in terms of availability of meats, fish, veggies, fruit, etc?
2. Should hygiene also be a consideration? I'm involved in international development work, so have some knowledge of food hygiene issues in some poorer countries. I know that Cuba's relatively high education and public health awareness could help mitigate this problem. But still, when food, refrigeration or electricity are scarce, particularly in a tropical climate, bad stuff can be cooked and sold.
3. I don't have much historical context. How unusual is this new development? Was the situation after the collapse of the Soviet Union like this? Any similar situations over the past 30 years?
4. Any sense/predictions about whether, when and how the situation could improve between now and next February?

Thanks for any thoughts.
