Highlights: First Quarter 2006
-
No emerging diseases identified although diagnostic submissions increase.
-
PMWS and other PCV2-associated disease diagnoses continue to decline although the trend persists for such diseases to occur more often in finishers.
-
PMWS diagnosed in a red river hog (Potomochoerus porcus), possibly the first report of PMWS in a species other than Sus scrofa.
-
The relatively dry weather may have resulted in less respiratory disease.
Overview
The GB DAPP (GB Deadweight Average Pig Price) declined from around 102p/kg dw at the start of January to just below 100p/kg at the end of March. Further details on DAPP and other pig industry topics are available on the BPEX website: http://www.bpex.org
NOTIFIABLE DISEASES:
No suspect incidents of swine fever or Aujeszky’s disease were reported that required statutory laboratory investigations.
ZOONOSES AND FOOD SAFETY: FOOD SAFETY INCIDENTS
No suspect incidents involving poisoning of pigs were reported.
SALMONELLAS & SALMONELLOSIS:
Salmonella incidents
The number of Salmonella Typhimurium incidents recorded for the first quarter of 2006 remained low, similar to the first and fourth quarters of 2005 with no appreciable trend differences.
Zoonoses Action Plan (ZAP)
ZAP investigation visits are now available to producers in ZAP category 2 as well as those in category 3. Recent visits have shown deficiencies on half the farms in their cleansing and disinfecting regimes – for example salmonellas were isolated from pens reportedly cleansed and disinfected.
BRUCELLOSIS
Brucellas were not isolated under the surveillance initiative to provide evidence that pig herds remain free of Brucella suis; an organism that has never been isolated from pigs or hares in the UK.
STREPTOCOCCAL INFECTIONS AND DISEASE
Streptococcus suis isolates
No reports were received of human infections. Twenty six Streptococcus suis isolates were serotyped this quarter as tabulated. Not all isolates represent disease incidents, however these followed previous patterns of streptococcal disease.
