Mathematical regression models for distribution of EHEC O26:H11 strain 21765 and EHEC O157:H7 strain EDL933 in the different milk phases after cream separation.

EHEC	Milk phase	% of EHEC population in milk phase	R2
O157:H7	RMFG	= -0.0466x3+0.9444x2-6.3913x+15.4520	1.0000
	RMS	= 0.0173x3-0.3068x2+1.7916x-3.4001	1.0000
O26:H11	RMFG	= -0.0027x3-0.0294x2+0.5470x-0.6497	0.9999
	RMS	= -0.0007x3+0.0895x2-0.8815x+2.2560	0.9937

All assays were performed in triplicate. RMFG, raw milk fat globule phase; RMS, raw milk skimmed phase.
