You don't really need the Roundup. Just dig up the grass, including the roots (means digging about 3-4" deep). That's what I did for my gardens, and I haven't had any problems with grass returning - I didn't even need landscape fabric (which I personally find to be more of a nuisance than anything).
In terms of safety - it's not believed to be especially toxic to humans or animals, and isn't really a safety concern if you use it properly (i.e. follow the directions). Health Canada is currently re-evaluating this pesticide though, and the allowable uses could change. There is a bit of recent data about possible endocrine disruption, and using it around young kids or pregnant women maybe isn't the best idea. Personally I wouldn't use it anywhere I was growing vegetables in the near future just as a matter of erring on the side of caution, even though it is used on food crops (why use it if it isn't needed?).
