Fears Rise Among Farmers as Foot-and-Mouth Disease Spreads in Europe

Recent outbreaks of foot-and-mouth disease have triggered significant concern among livestock farmers in Europe. The situation escalated in mid-January when a small herd of water buffalo near Berlin, Germany, was confirmed to be infected with this highly contagious disease. By March, cases were identified across various cattle farms in northern Hungary and Slovakia, close to the Austrian border. These incidents have led to widespread panic among farmers in the region and prompted extensive restrictions across borders.

Foot-and-mouth disease, caused by a picornavirus, affects all cloven-hoofed animals, including cattle, goats, pigs, deer, and elk. Infected cattle typically exhibit symptoms such as fever and a loss of appetite, alongside the development of painful blisters in their mouths and between their hooves, which can also occur on their udders. The disease results in excessive salivation, refusal to eat, and lameness. Symptoms in pigs are less pronounced but include fever and lameness due to blisters on their hooves. According to state epidemiologist Karl Ståhl from the Swedish Veterinary Institute, this disease is regarded as one of the most severe threats to domestic livestock. Under the epizootic disease law, any suspicion of foot-and-mouth disease mandates immediate veterinary consultation.

When a herd is infected, all animals must be culled to contain the outbreak. Additionally, various restrictions are enforced, including bans on the transport of all potentially infected animals. Currently, several border crossings between Slovakia and Austria are closed, with other nations, such as Estonia and the Czech Republic, preparing for possible outbreaks.

As for Sweden, which has not reported any cases of foot-and-mouth disease since 1960, the probability of the disease entering the country has increased, although it remains low. Ståhl explains that for an outbreak to occur in Sweden, a sequence of unlikely events must happen. This includes an individual visiting an infected area, coming into contact with the virus, and then introducing it back to Sweden, where it would need to survive the journey and infect a cloven-hoofed animal. Such a scenario is not impossible, but the overall risk remains minimal.

Interestingly, the outbreak in Germany is unrelated to the cases in Hungary and Slovakia, as they are caused by different strains of the virus. This divergence has led some in Hungary to speculate about a potential 'biological attack.' With Europe free from foot-and-mouth disease for many years, the sudden emergence of two independent outbreaks has raised eyebrows. Ståhl suggests that the infected water buffaloes in Germany could be linked to a similar virus present in Turkey, suggesting that travelers returning to Berlin from Turkey around New Year's might have inadvertently transported the virus, potentially exposing wildlife in a popular area near Berlin.

To combat the spread of the disease, stringent measures are being implemented, including the disinfection of vehicles at border crossings to prevent contamination.
