I'm writing (very slowly....
) a book on pregnancy and parenting. Here is a synopsis of actual research (as opposed to a lot of paranoid pregnant women spouting nonsense.....) on listeria: (Bear in mind I live in the States - these figures are relevant to a U.S. population, but I'm sure you can understand the point):
'On average, from 1998-2008, 2.4 outbreaks per year (of listeria) were reported to the CDC. Before 2011, the largest outbreak occurred in 2002, when 54 illnesses, 8 deaths, and 3 fetal deaths in 9 states (emphasis mine) were found to be associated with consumption of contaminated turkey deli meat. The population of the United States, according to the most recent data available at the time of writing (July 2011), is 311,591,917. Statistically speaking, therefore, and using the most conservative data available (i.e. the figures from the worst outbreak in recent history) you have a one in 57,702,20.7 chance of contracting listeria. Using this information, you may decide that the delicious looking piece of feta at the buffet table is less likely to kill you than you thought....'
If you really want to avoid something in pregnancy, don't get in a car! The highest cause of fetal death is maternal death, the highest cause of maternal death in pregnancy is road traffic accidents.
And I'm currently preg with DC3, btw! Yes, I do understand the need to feel you are protecting your baby, but I prefer evidence-based medicine to witchery-voodoo. OP, I'm with you all the way.....
