Raw shellfish consumption among renal disease patients: A risk factor for severe Vibrio vulnificus infection
Background: Raw shellfish-associated Vibrio vulnificus septicemia, with a case-fatality rate of nearly 50%, occurs most commonly in immunocompromised patients or those with liver disease. Methods: Sixty patients with renal disease treated with hemodialysis at The George Washington University and awaiting renal transplantation completed an initial survey that assessed their raw shellfish eating habits and knowledge regarding the pathogen V. vulnificus. Patients were then given educational materials describing the risks of eating raw shellfish and, one month later, completed a second survey that assessed their knowledge retention and intent to eat or not eat raw shellfish in the future. Results: Sixty of 68 (88%) eligible patients completed the survey. Forty-eight percent of patients reported having eaten raw shellfish after being diagnosed with kidney disease, with the highest rates reported among subjects ≤ 49 years old and subjects with more than a high school education. Prior to receiving the educational materials, no patient had heard of the pathogen V. vulnificus. Three quarters of patients reported never having been advised by a physician to avoid eating raw shellfish. One month after reading the educational materials, 75% of patients said they would refrain from eating raw shellfish in the future. Conclusions: In view of their immunocompromised status, patients with end-stage renal disease should be counseled to abstain from eating raw shellfish
Raw Shellfish Consumption in California: The 1992 California Behavioral Risk Factor Survey
Long-term comparison of antibiotic resistance in Vibrio cholerae O1 and Shigella species between urban and rural Bangladesh
From 2000 to 2012, Vibrio cholerae O1 and Shigella species isolates from urban Dhaka and rural Matlab were tested for resistance to all clinically relevant antibiotics in Bangladesh. Resistances in urban and rural Bangladesh tended to rise and fall together, especially a few years after the introduction of new resistance
Comparing Characteristics of Sporadic and Outbreak-Associated Foodborne Illnesses, United States, 2004–2011
Outbreak data have been used to estimate the proportion of illnesses attributable to different foods. Applying outbreak-based attribution estimates to nonoutbreak foodborne illnesses requires an assumption of similar exposure pathways for outbreak and sporadic illnesses. This assumption cannot be tested, but other comparisons can assess its veracity. Our study compares demographic, clinical, temporal, and geographic characteristics of outbreak and sporadic illnesses from Campylobacter, Escherichia coli O157, Listeria, and Salmonella bacteria ascertained by the Foodborne Diseases Active Surveillance Network (FoodNet). Differences among FoodNet sites in outbreak and sporadic illnesses might reflect differences in surveillance practices. For Campylobacter, Listeria, and Escherichia coli O157, outbreak and sporadic illnesses are similar for severity, sex, and age. For Salmonella, outbreak and sporadic illnesses are similar for severity and sex. Nevertheless, the percentage of outbreak illnesses in the youngest age category was lower. Therefore, we do not reject the assumption that outbreak and sporadic illnesses are similar
Infectious Dose of Listeria monocytogenes in Outbreak Linked to Ice Cream, United States, 2015
The relationship between the number of ingested Listeria monocytogenes cells in food and the likelihood of developing listeriosis is not well understood. Data from an outbreak of listeriosis linked to milkshakes made from ice cream produced in 1 factory showed that contaminated products were distributed widely to the public without any reported cases, except for 4 cases of severe illness in persons who were highly susceptible. The ingestion of high doses of L. monocytogenes by these patients infected through milkshakes was unlikely if possible additional contamination associated with the preparation of the milkshake is ruled out. This outbreak illustrated that the vast majority of the population did not become ill after ingesting a low level of L. monocytogenes but raises the question of listeriosis cases in highly susceptible persons after distribution of low-level contaminated products that did not support the growth of this pathogen
