On 26th June 2014 Latvia notified first case of African swine fever (ASF) in three wild boar found dead on the border with Belarus.

On the 26th June NRL confirmed ASF outbreak in three domestic pigs in one back yard holding in Krāslava county, Robežnieki parish about 6 km from Belarus border.

Biosecurity for pig farms – legal requirements

• No biosecurity requirements for pig farms before ASF introduction in Latvia (June 2104)

• The first legal requirements approved in July 2014:

- very strict biosecurity rules

- similar requirements for all type of pig farms including backyards

• Pre-emptive slaughter program in place (July-November 2014) in the ASF infected/risk areas

- 5930 pigs slaughtered in 1630 farms;

- The owner signed document – no pig keeping for at least

12 months;

- Compensation from government.

Biosecurity requirements for pig farms – state of play

The Regulation of the Cabinet of Ministers on biosecurity requirements was amended in November 2014 stating that:

• different biosecurity rules for commercial and non-commercial pig farms:

- implementation of biosecurity plan for commercial farms

- the list of biosecurity requirements for non- commercial (backyards) farms

Page 18: African swine fever in Latvia: outbreaks, biosecurity ... · African swine fever in Latvia: outbreaks, biosecurity measures and trade aspects Nordic-Baltic VCG Seminar Vilnius, 12-13

Main requirements for backyard farms: Only indoor keeping No swill feeding No fresh grass feeding Regular cleaning, disinfection, rodent & insect

control Disinfection pad at the entrance of farm Specific clothes / boots for use only in a farm No entrance for unauthorized persons Water resistant container for dead animals Protective clothing and boots for visitors Registration of visitors

Derogations – legal basis

Commission Implementation Decision 2014/709/EU Pig movement from Part II and Part III: - the pigs have been resident for a period of at least 30 days or since birth

on the holding and no live pigs have been introduced into that holding from the areas listed in Parts II, III and IV of the Annex during a period of at least 30 days prior to the date of the movement, and

- Pigs come from holding that has been subjected at least twice a year, with an interval of at least 4 months, to inspections by the CA;

- Laboratory testing of pigs;

- Biosecurity.

Conclusions

1. There are tools enough for the efficient control

of ASF in pig farms.

2. ASF virus continue to spread in wild boar

population despite of control measures applied.

3. Good biosecurity is essential to prevent pig

farms from ASF introduction.

4. Commercial farms located in areas where ASF is

present in wild boar population (Part II) are still

suffering from trade restrictions.
