A dramatic drop in milk yield is often the first sign of FMD in dairy herds. FMD virus excretion in milk, often at high titre, can take place for up to 4 days before the onset of clinical signs and continues for several days after typical lesions appear. It is therefore useful to collect milk from lactating animals in which FMD is suspected. Milk should be collected into a plain glass tube and kept at 4°C until submitted to the laboratory. If there is any possibility of delay, the milk should be frozen to prevent a fall in pH resulting in inactivation of the virus. |
