Ability to candle eggs is becoming more and more important to farmers, merchants, and shippers in the country districts. Laws in many States impose a penalty for selling bad eggs and the Federal Food and Drugs Act prohibits the interstate shipment of cases containing substantial percentages of bad eggs, which are held to be adulterated food. Only by candling can a shipper make certain that his eggs comply with Federal, State, and other regula- tions. Aside from its value in enabling one to comply with legal require- ments, ability to judge the condition of eggs in the shell has a distinct monetary application and in many sections is simply a matter of economic self-protection for the farmer and the country dealer. The custom of buying eggs on a grading basis is spreading rapidly, and the collectors in the great market centers are becoming much stricter in rejecting inedible eggs, just as consumers are becoming more criti- cal and are refusing to pay for doubtful eggs delivered to them by the retailer. The producer or country shipper who ships uncandlecl eggs runs the risk, therefore, of losing freight charges and packing costs on all inedible eggs, and where such eggs are included may get.
