According to The Soil Association, a recent government survey shows that organic laying hen farms have a significantly lower level of Salmonella.
According to an article on Natural Choices, The Association states that this study showed that 23.4% of farms with caged hens tested positive for salmonella compared to 4.4% in organic flocks and 6.5% in free-range flocks.
The research also apparently showed that the highest prevalence of salmonella occurred in the largest holding size category (>30,000 birds). This was over four times the average level of salmonella found in flocks closer to the maximum size allowed under Soil Association organic standards.
