I have an emergency meal in the cupboard - it's potato rosti in a packet, jar of frankfurter sausages and a tin of peaches. I can feed six on a campstove with it. Also have a first aid kit of course and I used to try to keep bottled water in though that has slipped lately.
Do you mean a bag to pack? If so, I'd add things like disinfectant and some sheets - multiple uses from clothing to floor covering to bandages.
Don't know how apocalyptic an imagination you need to have
following the floods last year and the slightly scary scenes when they were trying to distribute drinking water I was thinking of investing in a water filter - we can all survive without food for a while but I don't fancy having to give my children untreated water
FEMA - the US government website have quite comprehensive kit lists but I think I could end up filling the entire spare room with all that they recommend....
Do you know - I don't and I felt that I should definitely get one for the car as was at a cricket match on Sunday when my 4year old was stung by a bee. Well I was amazed at how many mums produced their emergency medical kits with 'zappers' to remove the sting, anti histemine (sorry - can't spell!) and creams to deal with the sting. What a life-saver!!
