Layers - Salmonella Testing Requirements for Laying Birds

Free Range Layers

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

Please take:

1 gauze swab (blue Sponge) from EACH of the following NINE areas PER HOUSE

  • Floors surfaces (including cracked areas)
  • Walls (including cracked areas)
  • High beams/ledges and pipe-work
  • Fans & fan housing
  • Manure belts/droppings board, scratching areas
  • In-house open feed hoppers/feeders
  • Drinkers/nipple spillage troughs/cups
  • Nest boxes/cage interiors
  • Egg delivery belts/elevators

These may be tested in 1 or more composites.

Also take up to 25g of rodent faeces, from surfaces in house, or service area if none available in house.

If none available, producer is to sign a declaration and take gauze swab from areas around bait boxes.

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

Commencing at 22-26 weeks of age

Take from ALL flocks 2 x 150g faeces from end of belts, scrapers or pits PER HOUSE every 15 weeks until depletion.

  • It is important to ensure that belts and scrapers are run on the day of sampling to collect fresh material before the samples are collected
  • Pooled faeces which have lodges on the scrapers or end of belts after they have been run is collected
  • In step-cage systems where belts and scrapers have not been installed, faeces is to be collected from the deep pit.
  • Samples are to be collected with the use of gloved hands, inverted bags or spatulas.
  • Faeces from belts and scrapers from all rows and tiers of cages should be collected. If composite faeces are collected from dropping pits, then collect at least 60 pinches of fresh surface material from different areas around the house where it is safe to do so.


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.
