Thanks for the calculations HotI, that is always how I look at risk, everything has a risk so I find it easier to compare the level of risk and then make a decision. ( I chose to eat pretty much whatever but was more careful about hygeine standards, e.g no morning tea buffets at work that had been stood round forever etc) and I have to say the fact other countries Spain, France, Japan etc eating foods considered high risk here did weigh into my decision). What I also found interesting is that foods often end up on that list that you get given at docs etc, due to one specific outbreak and are never removed, so the list is just getting bigger and bigger. E.g Alfafa sprouts ended up on there after a specific incident. Europe had an issue I think with cucumbers last year etc. If things keep getting added without clear indication of risk (or even clearly stating whether is listeria,salmonella etc) from that specific item, it limits our ability to have a choice having all lumped in together. Soon we wouldn't be able to eat anything.

On the figures it is also entirely possible that those maternal infections were not from foods considered to be high risk for listeria.
