Cynhaliwyd yr erlyniad yn dilyn archwiliad o’r busnes wyau pan ganfuwyd nad oedd prawf salmonela wedi’i gynnal o’r haid o fewn y cyfnodau amser penodedig ac iddo roi wyau bwrdd Dosbarth A i'w bwyta gan bobl ar y farchnad. Nid oedd yn hysbys beth oedd statws iechyd y wyau hynny ac ni ddylent felly fod wedi'u gwerthu.
The prosecution followed an inspection of the egg business which found they had failed to test their flock for salmonella within the prescribed time periods and placed onto the market eggs as Class A table eggs for human consumption. Those eggs were of unknown health status and should not have been sold in that way.
