Australia's food authority has restructured the advice for pregnant women. The warning includes likely danger posed by listeria bacteria.

In OZ one can find bread products being sold with added vitamins from the past one year but women are being advised to continue their folic acid and iodine dose.

Food Standards Australia New Zealand chief scientist Dr Paul Brent said, "Women can often rely on female friends and relatives for advice when they become pregnant but much of this current advice from FSANZ is based on the latest science. Listeria is a food poisoning bacteria that causes few or no symptoms in most people but can be very dangerous if you are pregnant for your unborn child or newborn baby."

Reports stated the food likely to contain listeria were cold cooked meat, chicken and salads, whether consumed inside or outside the home. Other foods that might have the bacteria were soft serve ice cream, unpasteurised dairy products, chilled seafood and vegetables served from salad bars.

Bakers were last year asked to add iodized salt to their preparations rather than common salt. According to health experts this would fulfill iodine needs of most of the population. Especially in pregnant and breastfeeding mothers who need iodine.
