Comparison of the icELISA with HPLC-MS/MS for determination of ZEN in actual samples.

Samples	Sample Number	Positive Sample Number		Positive Rate (%)	Positive Sample Content Range (μg/L)		CV (%)
		icELISA a	HPLC-MS/MS b		icELISA a	HPLC-MS/MS b
Maize meal	6	2	2	33.33	5.62–48.73	5.45–47.21	9.7
Wheat meal	6	1	1	16.67	23.51	22.84	11.2
Pig feed	6	2	2	33.33	21.42–64.36	20.78–62.81	10.1
Positive maize meal	2	2	2	100	24.62–66.35	23.15–36.42	9.8
Positive pig feed	2	2	2	100	37.22–71.54	36.38–71.69	10.6
Total	22	9	9	40.91	5.62–71.54	5.45–71.69	9.8–11.2

Note: ^a Results were determined using a heteroglogous icELISA format. ^b Results were determined via HPLC-MS/MS.
