Animals get sick because they are kept in cramped conditions in factory farming systems! - is this factual?

Strict EU and national control measures with strong biosecurity guidelines are generally in place to uphold animal health. And Europe’s farm-to-fork monitoring system includes key policies for animal health management, which is supported by a wide availability of preventive solutions, like vaccines, or diagnostics for early detection, as well as therapeutic treatments. No matter the farm size or practice, good animal health is on the whole reliant on sound farm management, and continued cooperation between the relevant stakeholders in Europe. 

Each system has its merits and its challenges. For example, contrary to some beliefs, free range animal housing systems can present some challenges, which can of course be overcome through increased vigilance and reinforced biosecurity measures. Overall, there is general consensus that no matter the holdings, healthier herds mean better yields, so it is always in the farmer’s interest to ensure the good health and welfare of their animals.
