Table 1

Distribution of AFs in maize products from some Kenyan districts following the 2004 aflatoxicosis.

District	Number of samples^a	Total aflatoxin concentration^b
		≤20 μg/kg (%)	21–99 μg/kg (%)	100–1,000 μg/kg (%)	>1,000 μg/kg (%)
Makueni	91	32 (35)	12 (13)	36 (40)	11 (12)
Kitui	73	28 (38)	15 (21)	23 (32)	7 (10)
Machakos	102	50 (49)	26 (25)	23 (23)	3 (3)
Thika	76	50 (66)	13 (17)	10 (13)	3 (4)
Total	342	160 (47)	66 (19)	92 (27)	24 (7)

Excerpted from Lewis et al. [71]. Values shown were for samples with AFs and the percentage of total samples within the district. ^aNumber of samples analyzed for AFs, did not include samples that were collected but not analyzed. ^bAcceptable upper limit for AFs in grains by then was 20 μg/kg.
