2 Broiler Production Average farm size is 3.23 houses for Tyson Foods Tyson Foods has 5,852 broiler farms with 18,901 houses Median number of flocks placed per farm is 5-6 Median number of broiler farms per complex is Broiler farms with more than 100,000 birds per farm make up 93% of production for all of industry

5 Introduction: Heat Sterilization, An Old Idea Louis Pasteur first to recommend surgeons flame hands to prevent contamination Heat widely used in sterilization Heat very forgiving no residues, no resistance Blow lamp tested in 1940 for effectiveness against coccidia

6 Heat Sanitation: New Application Most chemical disinfectants limited effectiveness in organic matter Bacterial spores, viruses, worm eggs and fungi resistant to many of chemical disinfectants Turkey company first to develop flamer in attempt to burn out corona virus

11 Poultry Sanitizer Evaluations Turkey Brood House Litter removed Washed and disinfected Sterile drag swabs Zig-zag through house on both sides Pre and post Flame samples CFU/sponge E. coli, coliforms Incidence of Salmonella

12 Effect of Floor Flaming on E. coli and Coliform Levels CFU/ 150 sponge PRE POST 50 0 E Coli Coliforms Pr >.0001 N= 4 Pr > Log Reduction 99% Kill

13 Effect of Floor Flaming on Total Aerobic Bacteria CFU/ Sponge Aerobic Bacteria N= 4 Pr > Log Reduction 99 % Kill PRE POST

14 Effect of Flamer on Litter Microbial Populations Farm 1-1 flamed litter surface in four broiler houses Litter used for 6 flocks Pre and post drag swabs, 2 sites/house Farm 2-flamed 2 litter surface in two houses Determined CFU/sponge Total aerobic bacteria, E. coli, coliform Incidence of Salmonella

18 Flock Performance Pounds Control Houses 6.04 Burn Houses Average market weight of birds N=8 houses

19 Flock Livability For Birds Reared on Flamed Litter % Burn Houses Control Houses Flamed House livability reflects high first week mortality for one house

20 Clostridium Evaluation Farm 1 was broiler house with gangrenous dermatitis outbreak 6 areas sampled Farm 2 had a botulism problem 2 areas sampled Flamed floor after clean out Drag swab pre and post burn

21 Effect of Flaming on Clostridium Levels in Broiler House Floor 2000 CFU/ sponge PRE POST 500 a 121 b 0 FARM 1 N=12 P=.0007

22 Effect of Flaming on Clostridium Levels in a Broiler House Floor CFU/ sponge FARM 2 N=4 P=.1628 PRE POST

23 Sanitizer Used on Farm With E. Coli Outbreak First flock on new litter High incidence of E. Coli beginning week one Litter surface for two houses was flamed immediately after flock loadout Drag swabs taken pre and post flaming Measured total aerobic bacteria, E. coli, coliform,, yeast and mold

24 Total Aerobic Bacteria in Litter Surface CFU/ Sponge Pre Post Pr > F=.0001

25 Effect of Flaming Litter Surface on E. coli and Coliform Levels CFU/ Sponge E. Coli Coliforms Pre Post Pr >.0007 Pr >.0001

26 Total Yeast and Mold in Litter Surface 6000 CFU/ Sponge Yeast Mold Pr >.0001 Pr >.0260 Pre Post

31 Conclusion Flame Sanitizer can be an effective tool in a sanitation program Provides options to reduce pathogen load in production facilities Will not replace good sanitation and management Challenge is to promote Flame Sanitizer as safe alternative to chemical treatments
