Effect of LGEO on pre-formed Salmonella Heidelberg (Isolates 466 and 1904) biofilms with 2-h exposure time to the treatment (means^⁎ ± SE; n = 8/treatment).

	Biofilm-Associated S. Heidelberg (Log10 CFU/mL)
Treatments	S. Heidelberg 466	S. Heidelberg 1904
Positive Control	7.5 ± 0.14^c	7.3 ± 0.11^c
0.0075% LGEO	7.1 ± 0.13^b	6.9 ± 0.17^b
0.15% LGEO	NG^a	NG^a
1% LGEO	NG^a	NG^a

NG = No growth observed by surface plating
