To the Editor. —
This letter concerns an article that appeared in JAMA on April 8, 1988, entitled "The Emergence of Grade A Eggs as a Major Source of Salmonella enteritidis Infections."1When I observed the title of this aritcle, my immediate reaction was one of concern. It appeared that a severe epidemic had started in the northeastern United States and was threatening to sweep the country. The summary raised the possibility of hens with infected ovaries spreading a dangerous pathogen in one of our most important food supplies.After analyzing the article, however, it became evident that the authors prepared the article after completing only a small research project that had little substance and was poorly designed. All they did was take 50 samples of bulk eggs from the Northeast region and 25 samples of bulk eggs from each of the other three US regions and test them
