Layers - Salmonella Testing Requirements for Breeder Laying Units

Post Cleaning and prior to a new flock going into the house:

Please take:

1 gauze swab or sponge pad, from EACH of the following 8 areas PER HOUSE

  • Floors (including cracked areas)
  • Walls (including cracked areas)
  • High beams/ledges and pipe-work
  • Fans & fan housing
  • In-house open feed hoppers/feeders
  • Drinkers
  • Nest boxes
  • Egg delivery belts

These may be tested in one or more composites.

If a previous flock has tested positive for Salmonella Enteritidis or Salmonella Typimurium. Please see us for an alternative testing kit.

Every 2 Weeks

5 pairs of boot swabs PER HOUSE (pooled into minimum of 2 pools per flock).

Every 6 weeks (Commencing at 24 weeks of age)

50g dust, or all readily available dust if less available, collected from at least 10 locations in EACH HOUSE before dusting/sweeping, every 6 weeks (1 composite per house)

Official Sampling (3 times during lay – within 4 weeks of transfer, within 8 weeks of depletion and halfway in-between)

5 Pairs of boot swabs PER HOUSE (pooled into minimum of 2 pools PER FLOCK)


All samples should be dispatched within 24 hours of collection. The BEIC Lion Code require all producers to ensure that the time between sampling and the lab starting to process the sample to be no later than 48 hours

For samples that fall outside of this time frame will not be able to have the laboratories UKAS accreditation mark on their salmonella results.

To avoid this please ensure samples are sent and received within 48 hours of sampling, it is therefore, not advisable to send samples on a Friday or Saturday, as they will not be tested until the following Monday, which will result in the 48 hour rule being breached.
