Pig gastroenteritis alert

PIG producers have been warned to look out for symptoms of gastro-enteritis in their herds after MAFF confirmed a case in South Lincs this week.

The non-notifiable but highly infectious viral disease causes diarrhoea, vomiting and anorexia with a high degree of mortality.

Producers in the area have been advised to review disease security measures and take steps to ensure pig units are bird-proof as wild birds can spread the virus.

The last major outbreak of the disease, which was endemic in the 1950s, was in 1983. Its virtual absence since then has been down to the emergence in 1986 of porcine respiratory corona virus, which as a mutant of TGE , appears to have immunised the pig population. &#42
