  1. A NOVEL APPROACH TO FOOT DIPPING Robert L. Owen and John Lawlor

  2. The Problem • Biosecurity is a year round obligation • In some parts of the country, foot dipping is impossible at certain times of the year. • Universally, foot pans are inadequately maintained.

  3. The Solution • Ignore that the problem exists • Discontinue use of foot pans • Utilize pump up sprayers filled with disinfectant • How about a dry foot bath?

  4. Question 1 Are foot pan solutions effective at reducing the numbers of bacteria on shoes of hatchery workers?

  5. Total Bacterial Counts from Shoe Swabs

  6. Question 2 How long does a foot pan solution stay clean in a hatchery environment?

  7. Total bacterial count of the solution

  8. Materials and Methods • A total of 5 dry products were tested • Early testing was for efficacy of Salmonella control only • Based on these results 2 of the 5 original products were dropped due to lack of efficacy or cost • Remaining products were tested versus currently used liquid products

  9. Testing Procedure • Swab was collected from the sole of the technician’s shoe before stepping into test pan • Stood in test pan for 10 second contact time • Shoe was again swabbed after stepping out of test pan • Samples were directly plated on TSA and incubated 37oC for 18 to 24 hours • Colonies enumerated by direct count • >400 classified as TNTC • Repeated daily until efficacy was lost

  10. Results

  11. Materials and Methods: Trial 2 • Actually done in the hatchery • Employee’s shoe was swabbed before stepping into test pan • Between Chick Room and Break Room • Real World 5 to 10 second contact time

  12. Results – Trial 2

  13. Conclusions • Duration of effectiveness for solution in foot pans is very short under field conditions • Dry disinfectants are effective at reducing bacterial numbers on shoes • Duration of effectiveness for dry disinfectants is substantially longer than for solutions

  14. Practical Applications • Real goal is to reduce tracking of bacteria – especially Salmonella • Only part of an overall biosecurity program

  15. Entrance to Chicken House

  16. Biosecurity Building

  17. Inside The Hatchery

  18. Acknowledgments • Tony Britt, Hatchery Manager, Pikeville, TN • Technical Support • Melissa Poulson • Amanda Harvey • Tara Stroope • Lena Shipley
