Carry over (transfer) of feed-borne acrylamide into eggs, muscle, serum, and faeces - A pilot study with Japanese quails (Coturnix coturnix japonica)

Two groups of 10 quails each were fed for 30 days on a diet containing either 663 μg feed-borne acrylamide (AA)/kg feed (group B) or 2472 μg AA/kg feed (group C) respectively. The concentrations of AA present in excreta and eggs were compared with those measured in eggs and excreta obtained from a control group (group A) fed on a diet low in AA (<10 μg/kg). The results clearly showed that the eggs of quails in group C contained approximately 53-112 μg AA/kg based on dry weight, while eggs collected from group A did not contain AA (limit of detection in eggs 3.5 μg/kg). Nearly 5% of the AA fed was recovered in the excreta. The AA concentrations in liver, muscle and serum were detectable, but below the limit of quantitation.
