Listeria monocytogenes Illness and Deaths Associated With Ongoing Contamination of a Multiregional Brand of Ice Cream Products, United States, 2010-2015.

BACKGROUND: Frozen foods have rarely been linked to Listeria monocytogenes illness. We describe an outbreak investigation prompted by both hospital clustering of illnesses and product testing. METHODS: We identified outbreak-associated listeriosis cases using whole-genome sequencing (WGS), product testing results, and epidemiologic linkage to cases in the same Kansas hospital. We reviewed hospital medical and dietary records, product invoices, and molecular subtyping results. Federal and state officials tested product and environmental samples for L. monocytogenes. RESULTS: Kansas officials were investigating 5 cases of listeriosis at a single hospital when, simultaneously, unrelated sampling for a study in South Carolina identified L. monocytogenes in Company A ice cream products made in Texas. Isolates from 4 patients and Company A products were closely related by WGS, and the 4 patients with known exposures had consumed milkshakes made with Company A ice cream while hospitalized. Further testing identified L. monocytogenes in ice cream produced in a second Company A production facility in Oklahoma; these isolates were closely related by WGS to those from 5 patients in 3 other states. These 10 illnesses, involving 3 deaths, occurred from 2010 through 2015. Company A ultimately recalled all products. CONCLUSIONS: In this US outbreak of listeriosis linked to a widely distributed brand of ice cream, WGS and product sampling helped link cases spanning 5 years to 2 production facilities, indicating longstanding contamination. Comprehensive sanitation controls and environmental and product testing for L. monocytogenes with regulatory oversight should be implemented for ice cream production.

Trends in County-Level COVID-19 Incidence in Counties With and Without a Mask Mandate - Kansas, June 1-August 23, 2020.

Wearing masks is a CDC-recommended* approach to reduce the spread of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), by reducing the spread of respiratory droplets into the air when a person coughs, sneezes, or talks and by reducing the inhalation of these droplets by the wearer. On July 2, 2020, the governor of Kansas issued an executive order† (state mandate), effective July 3, requiring masks or other face coverings in public spaces. CDC and the Kansas Department of Health and Environment analyzed trends in county-level COVID-19 incidence before (June 1-July 2) and after (July 3-August 23) the governor's executive order among counties that ultimately had a mask mandate in place and those that did not. As of August 11, 24 of Kansas's 105 counties did not opt out of the state mandate§ or adopted their own mask mandate shortly before or after the state mandate was issued; 81 counties opted out of the state mandate, as permitted by state law, and did not adopt their own mask mandate. After the governor's executive order, COVID-19 incidence (calculated as the 7-day rolling average number of new daily cases per 100,000 population) decreased (mean decrease of 0.08 cases per 100,000 per day; net decrease of 6%) among counties with a mask mandate (mandated counties) but continued to increase (mean increase of 0.11 cases per 100,000 per day; net increase of 100%) among counties without a mask mandate (nonmandated counties). The decrease in cases among mandated counties and the continued increase in cases in nonmandated counties adds to the evidence supporting the importance of wearing masks and implementing policies requiring their use to mitigate the spread of SARS-CoV-2 (1-6). Community-level mitigation strategies emphasizing wearing masks, maintaining physical distance, staying at home when ill, and enhancing hygiene practices can help reduce transmission of SARS-CoV-2.

Novel thogotovirus associated with febrile illness and death, United States, 2014.

A previously healthy man from eastern Kansas, USA, sought medical care in late spring because of a history of tick bite, fever, and fatigue. The patient had thrombocytopenia and leukopenia and was given doxycycline for a presumed tickborne illness. His condition did not improve. Multiorgan failure developed, and he died 11 days after illness onset from cardiopulmonary arrest. Molecular and serologic testing results for known tickborne pathogens were negative. However, testing of a specimen for antibodies against Heartland virus by using plaque reduction neutralization indicated the presence of another virus. Next-generation sequencing and phylogenetic analysis identified the virus as a novel member of the genus Thogotovirus.

Outbreak of cryptosporidiosis among responders to a rollover of a truck carrying calves - Kansas, April 2013.

In April 2013, the Thomas County Health Department notified the Kansas Department of Health and Environment's Infectious Disease Epidemiology and Response section (KDHE) of two cases of cryptosporidiosis among emergency responders to a tractor-trailer rollover. The truck was carrying approximately 350 preweaned Holstein calves. An outbreak investigation was led by KDHE with assistance from the county health department; six cases of cryptosporidiosis were identified among the 15 emergency responders. No additional primary cases with this exposure or secondary cases were identified. Disease was associated with carrying calves (relative risk [RR] = 3.0) and contact with fecal matter (RR = 4.5). The calves were aged <10 days and reportedly suffered from scours (diarrheal disease), which is often caused by Cryptosporidium spp., a chlorine-tolerant protozoan parasite. Because of the age of the calves and the conditions at the rollover scene, a high potential existed for fecal contamination and subsequent transmission of Cryptosporidium. This outbreak is the first report of both law enforcement and volunteer emergency responders contracting cryptosporidiosis, with transmission of Cryptosporidium attributed solely to direct contact with animals and their feces. Human illness resulting from contact with animals during an emergency response might be minimized if 1) all responders are aware of the potential for zoonotic transmission, 2) education is provided on proper animal handling including the use of appropriate personal protective equipment, and 3) responders practice thorough hand hygiene and decontaminate clothing and equipment following contact with feces.

Reasons for Turnover of Kansas Public Health Officials during the COVID-19 Pandemic.

Public health officials played a critical role in COVID-19 mitigation and response efforts. In Kansas, 51 local health department (LHD) administrators and/or local health officers left their positions due to the pandemic between 15 March 2020 and 31 August 2021. The purpose of this study was to identify factors that led to turnover of Kansas local public health officials during the COVID-19 pandemic. Those eligible to participate in this study included former LHD administrators and/or health officers who were employed at or contracted by a Kansas LHD on 15 March 2020 and resigned, retired, or were asked to resign prior to 31 August 2021. Researchers used a demographic survey, a focus group, and key informant interviews to collect data. Twelve former LHD leaders participated in this study. Four themes emerged from phenomenological analysis: politicization of public health; a perceived lack of support; stress and burnout; and the public health infrastructure not working. The findings of this study can guide the Kansas public health system to address the issues leading to turnover of leadership and prevent future turnover. Future research must explore strategies for mitigating leadership turnover and identify alternative public health structures that could be more effective.

The relationships of social participation and community ratings to health and health behaviors in areas with high and low population density.

Previous studies have linked social participation and community levels of trust with improved health status. We examined the associations between levels of community participation, self-reported community ratings (trust), and health within a public health surveillance survey conducted in Kansas (N=4601). Independent variables were individual ratings of their communities (excellent, very good, good/ fair, poor), and their involvement in community groups or organizations in the last 5 years (yes/no). Dependent variables were self-rated health status, depressive symptoms, physical activity, smoking, obesity, and binge drinking. After controlling for age, gender, race/ethnicity, education, and having a medical doctor, self-rated health status (p<0.001) and physical activity (PA) (p<0.001) were positively, and smoking (p<0.001) and depressive symptoms (p<0.001) were negatively associated with community ratings. Only PA (p<0.001) remained associated with community involvement in a multivariate analyses. Multilevel analysis using county-level data showed no significant interactions between population density and dependent variables. Individuals from rural areas had the highest community involvement but relatively low levels of community ratings. Our findings suggest that individuals in rural areas, especially in densely settled rural areas, may face increased risks of poor health.

Clonally related Burkholderia contaminans among ventilated patients without cystic fibrosis.

We investigated a cluster of 10 Burkholderia cepacia complex-positive cultures among ventilated patients and those with a tracheostomy in an acute care hospital. Isolates from 5 patients had outbreak-strain-related Burkholderia contaminans. Isolates of B. cepacia complex unrelated to the outbreak strain were cultured from a sink drain. The investigation identified practices that might have led to contamination of patient respiratory care supplies with tap water, which might have contributed to the cluster.

Emergency survey methods in acute cryptosporidiosis outbreak.

In August 2003, a communitywide outbreak of cryptosporidiosis occurred in Kansas. We conducted a case-control study to assess risk factors associated with Cryptosporidium infection by using the telephone survey infrastructure of the Behavioral Risk Factor Surveillance System. Using existing state-based infrastructure provides an innovative means for investigating acute outbreaks.

Use of a behavioral risk survey by employers to identify leading health problems among employees and their dependents.

In an effort to identify high-burden health conditions among employees and their families for worksite, community, and health care quality improvement interventions, The Mid-America Coalition on Health Care, with assistance from the Kansas Department of Health and Environment, conducted a broad behavioral risk survey among a random sample of employees of eight participating employers and their family members. By working with an established coalition of businesses, providers, payers, and other entities with a stake in controlling health care costs, state public health officials were able to assist the business community to adopt an acceptable approach to assessment of health risk and a community approach to risk reduction.
