Resumen
The mass media are recognized by many social scientists as important sources of medical information for lay people and as a positive influence on those working in the health care professions. However, there is a lack of study about print and mass media reporting on major health problems in developing countries such as Mexico. This article presents the findings of a study conducted to identify specific messages that the Mexican print media convey to the general reader about chronic diseases, especially one of the most important and pervasive, diabetes. We undertook a comprehensive review and content analysis of secondary source media reporting in the Boletin (Bulletin)-published by the Department of Education and Health, Universidad Autónoma Metropolitana, Xochimilco. The Boletin summarizes all articles related to health matters published in 12 national daily newspapers and 3 magazines. Our study covered all issues of the Boletin from 1992 through 1996. Our findings indicate that at times the press and popular print media disseminate an incomplete and often biased picture of chronic diseases prevalent in Mexico. Specifically, the press gives equal or more important coverage of acute diseases, or to AIDS, than to other major chronic conditions. The press also reproduces the biomedical model of disease and does not address topics important to certain segments of the population, including the patient. Moreover, the media may present an overly idealized impression of the capability of health services. Consequently, this failure to address the issues of certain widespread, chronic illnesses is severe enough to ask about the role of the press in medical health care reform. We conclude by suggesting areas for further research.

However, unsafe raw materials and inadequate food safety practices during cheese manufacture and preservation make them a potential public health risk. The incidence of Salmonella, Listeria, Escherichia coli O157:H7, and staphylococcal enterotoxin was analyzed in two types of fresh cheese (panela and adobera) commonly marketed in Mexico. A total of 200 samples, 100 panela and 100 adobera, were acquired from 100 wholesale milk product distributors who supply small retailers in the Guadalajara metropolitan area, Jalisco State, Mexico. Pathogens were identified using culture and immunoassay (miniVidas) methods. The presence of staphylococcal enterotoxin was determined by an immunoassay method. Of the 200 analyzed samples, 92 were positive for at least one of the pathogens. The incidence in the panela samples was 56%: 34% Salmonella, 16% E. coli O157:H7, and 6% L. monocytogenes. In the adobera samples, incidence was 36%: 20% Salmonella, 4% E. coli O157:H7, and 12% L. monocytogenes. Staphylococcal enterotoxin was not detected in any of the 200 samples. Choice of technique had no effect on detection of pathogen incidence, although the immunoassay method identified more Salmonella serotypes than the culture method. Handcrafted panela and adobera fresh cheeses in Mexico frequently contain pathogenic bacteria and therefore pose a public health risk. Copyright ", International Association for Food Protection.
