Occurrence and Exposure Assessment of Aflatoxin B₁ in Omena (Rastrineobola argentea) from Kenya

Table 2

Aflatoxin levels in Omena for human and fish feed production and risk assessment due to consumption of Omena.

Samples	N	Range (μg·kg^−1)	Mean ± SEM (μg·kg^−1)	% samples >20 μg·kg^−1	% samples >5 μg·kg^−1	EDI (ng·kg^−1·BW·day^−1)		MoE	Population risk for primary liver cancer (cancer/year/100,000 population)
						Mean	P95		Mean	P95
Omena for human consumption	42 (41)	2.01–49.30	19.42 ± 1.96^a	38.00	83.33	1.35	2.78	126.3	0.11	0.22
Omena for fish feed production	32 (31)	2.24–115.23	46.93 ± 6.17^b	75.00	93.75
Total	74 (72)

Values provided in parentheses under column N indicate the number of positive samples above the limit of detection (LOD); a, b = mean values followed by similar letter do not differ significantly (). BMDL10/exposure, where BMDL10 is the benchmark dose lower confidence limit of 10% of 170 ng·kg⁻¹·BW·day⁻¹, proposed by the European Food Safety Authority [24]. MoE: margin of exposure; EDI: estimated daily intake.
