This study was undertaken to relate quantitatively the aflatoxin residue found in eggs and tissues to the aflatoxin intake via feed. Eighteen hens were fed an aflatoxin B1 (B1)-contaminated feed (8 micrograms/g) for 7 days, after which half the group was sacrificed; the remainder were sacrificed after an additional 7 days on an aflatoxin-free diet. Eggs were collected over the entire 14-day period. Aflatoxicol (R0), B1, or both were found in eggs and tissues (kidneys, liver, muscle, blood, and ova). Aflatoxin M1 (M1) (.04 to .1 ng/g) was found only in the kidneys. Levels of R0 and B1 were approximately the same in eggs, ova, kidneys, and liver. In eggs, the levels of R0 and B1 (.02 to .2 ng/g) increased steadily for 4 or 5 days, after which time the levels plateaued and then decreased after B1 withdrawal at the same rate as they had increased. At 7 days after withdrawal, only trace amounts of R0 (.01 ng/g) remained in eggs. All tissues, except blood, from hens sacrificed immediately before aflatoxin withdrawal contained R0 (.04 to .4 ng/g) or R0 and B1 (.04 to .8 ng/g). The R0 (.03 to .11 ng/g) was the only aflatoxin detected in muscle, and B1 (.05 to .07 ng/g) was the only aflatoxin in blood. Seven days after aflatoxin withdrawal, B1 (.08 ng/g) was found in one of nine livers and R0 (.01 to .04 ng/g) in eight of nine muscles analyzed, but no aflatoxins were found in any other tissues. |
