Table 4.

Effect of sequential 2-minute dip treatments in 0 (Positive Control), 0.5, 1, or 2% LGEO (vol/vol) against S. Heidelberg attachment to broiler chicken skin and in treatment waters at scalding (54°C) then chilling (4°C) temperatures.

	S. Heidelberg (Log₁₀CFU/Sample)
Treatments	Skin	Chilling water	Scalding water
Positive Control	4.2 ± 0.06^c	3.1 ± 0.24^c	3.5 ± 0.21^b
0.5% LGEO	2.6 ± 0.36^b	0.4 ± 0.25^b	ND^a
1% LGEO	1.9 ± 0.39^ab	ND^a	ND^a
2% LGEO	0.9 ± 0.29^a	ND^a	ND^a

Abbreviation: ND, non-detectable by surface plating and enrichment.

^a–c

Values with different superscripts differed significantly at P < 0.05 column-wise within each sample.

^⁎least square means.

S. Heidelberg counts are expressed in log₁₀ CFU/sample (means* ± SE; n = 6 skin samples and n = 4 for water samples per treatment).
