Earlier this week, Farming Today reported on claims from the Ulster Society for the Prevention of Cruelty to Animals that the horse passports and microchipping system in Ireland had been abused - leading to horse meat being illegally traded and ending up in food. Now a leading horse welfare charity says the problem is being compounded by a legal agreement between Britain, France and Ireland. The Tripartite agreement allows almost free movement of horses between the three countries. It was set up 50 years ago to allow racehorses to travel to compete without having to go into quarantine, but in 2005 it was extended to cover more horses, and allows them to travel without health checks. Also on Farming Today, 70 percent of roses bought in the UK are imported from Kenya. Charlotte Smith finds out why growing on this scale has an impact on the environment.
