Salmonella levels in poultry higher in battery eggs

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.

“This research confirms the Soil Association’s view that there are serious potential human health implications from such intensive systems. Whilst Salmonella food poisoning can be avoided through proper cooking of eggs and meat, anything that reduces the incidence of this bug should be encouraged – like genuine free-range, organic farming,” said Emma Hockridge, Soil Association policy department.
