recent survey by the British government has revealed
that organic laying hen farms have a significantly
lower level of Salmonella, a bacterium that is the
most common cause of food poisoning worldwide.
More than 23 percent of farms
with caged hens tested positive for salmonella,
compared to just 4.4 percent in organic flocks and
6.5 percent in free-range flocks.
The highest prevalence of
salmonella occurred in the largest holding size
category (30,000 birds or more). They contained over
four times the average level of salmonella found in
flocks closer to the maximum size allowed under
British Soil Association organic standards.
