Salmonellosis remains an underlying threat in the Irish dairy herd

摘要

Salmonella is being increasingly identified as a cause of disease on farms throughout Ireland, and in specific regions not previously linked with the bacterial disease. The impact of salmonella infection on the productivity and profitability of cattleis well known and researched. A study conducted in Ireland found that in unvaccinated herds positive for exposure to salmonella, total profits per farm were reduced by €7,731, €9,471, and €11,211 compared with the negative baseline (unvaccinated negative herds) based on milk prices of €0.24, €0.29, and C0.34/L, respectively. In the same study, herds positive for exposure to salmonella were also recorded to have experienced a 316kg reduction in milk yield.1 It is also important to mention the significant zoonotic potential associated with salmonella infection. This is becoming a growing concern for many producers and veterinary surgeons, particularly from a public health perspective where both animal and human health are now becoming more intrinsically linked in the modern world.
