Transmission of aflatoxins into eggs and egg products

Aflatoxin tolerances already have been legislated for feed but for food regulations they are pending now enactment in West Germany. With this regard Japanese quail as well as white and brown laying hens (HNL-type) were fed continuously with rations containing 40 to 10 000 ppb of aflatoxin B₁ and 30...

Description
Summary:Aflatoxin tolerances already have been legislated for feed but for food regulations they are pending now enactment in West Germany. With this regard Japanese quail as well as white and brown laying hens (HNL-type) were fed continuously with rations containing 40 to 10 000 ppb of aflatoxin B₁ and 30 to 13 000 ppb of aflatoxin G₁ for 30, 56 and 28 days, respectively, to investigate the transmission of aflatoxins into eggs. The eggs from quail at the feeding level of 100 ppb aflatoxin B₁ contained measurable amounts of aflatoxin B₁, whereas 30- to 50-fold concentrations of aflatoxin B₁ were needed in the diet for detection of residues in eggs of white and brown laying hens. Aflatoxin B₁ was recovered as maxima of 2.5 as well as 0.4 and 0.2 ppb in the whole egg of quail, white and brown hens, respectively, at which slightly higher amounts were detected from yolk than from albumen. Aflatoxin G₁ residues also were determined in the eggs of poultry. Egg production by quail and hens fed continuously with rations containing about 10 000 ppb of aflatoxin B₁ ceased after a few days and thus excluded hazardous aflatoxin residues in the eggs. But high single oral doses of aflatoxin B₁ administered to laying hens could exceed slightly the maxima of recovered residues in the eggs. Regarding aflatoxin tolerances for feeds and foods the transmission of aflatoxins into eggs of laying white and brown hens as well as into eggs of quail poses no potential hazard to public health.
