Norovirus outbreaks are becoming common and environmental health professionals are trained and experienced in environmental controls, such as proper cleaning procedures, to halt outbreaks. But what happens when the environmental controls are not preventing the spread? What other methods of transmission should you consider? Learn in this session how one county investigated and halted a Norovirus outbreak that resulted from contaminated well water.

This session reviews an outbreak investigation conducted in a mega hotel in Jamaica. Along the way, we discover gaps in the investigation process, describe challenges in disease surveillance, and determine the barriers to effective outbreak prevention and control.

See how the existing regulations stack up against changing trends in the tourism sector and possible remedies for the shortcomings. Use this case study to identify the emerging challenges and possible solutions in your outbreak investigation process before they happen.

Food safety in hospitals is important to protect patients whose immunity may be compromised by their illness. The safety of food served to patients is dependent on its handling acquisition of raw food items, to preparation, packaging and distribution. The study described in this article assessed the knowledge and food handling practices of nurses in the food chain to patients in the hospital wards. The mean age of respondents was 33.7±9.3 years and 180 (56.6%) had worked in the hospital for 1–5 years. While respondents had good knowledge scores overall, only 22 (6.5%) knew the correct temperature for maintaining hot, ready-to-eat food. Also, 332 (97.6%) respondents knew the importance of hand washing before handling food while 279 (84.1%) always wash hands before handling food. The study revealed a decline in performance over time, from knowledge and attitudes to practice in food handling. Therefore, regular training on safe food handling procedures should be mainstreamed into the training curriculum of staff nurses in health care institutions.

Abstract

The Southern Nevada Health District (SNHD) began operation of a landlord–tenant hotline to address residential habitability complaints in 2011. There are limited studies describing such hotlines and the types of complaints experienced by callers in renter-occupied units (ROUs) anywhere in the U.S., much less in Clark County, Nevada. This study examined the hotline operation and found that it received almost 5,000 calls from March 2014–July 2016. Callers with complaints covered by the Nevada Revised Statute Chapter 118A, habitability of a dwelling, were eligible for participation in the Clark County Landlord–Tenant Hotline Study. The study collected additional data on 1,283 participants characterizing the population using the hotline and types of housing complaints reported. Callers typically were 38 ± 13.9 years old, female (75%), and the majority identified as non-Hispanic or Latino, Black/African American, or White. General maintenance, mold-like substances, and cockroaches were the top three complaints reported. SNHD inspectors conducted 290 site inspections of participant dwellings and validated the presence of the complaint(s) in the majority of cases. The findings presented here indicate a need for further investigation and continuation of services provided by the hotline.

Marijuana use has been legalized in some form in 34 states and the District of Columbia. Most of the laws limit prosecution of users, but are silent when discussing the affect on the EH regulatory community. This session will explore the impacts legalized marijuana has already had and will continue to have on the EH community.

Abstract

On July 9, 2013, an outbreak of Legionnaires’ disease (LD) was identified at Long-Term Care Facility A in central Ohio. This article describes the investigation of the outbreak and identification of the outbreak source, a cooling tower using an automated biocide delivery system. In total, 39 outbreak LD cases were identified; among these, six patients died. Water samples from a cooling tower were positive for Legionella pneumophila serogroup 1, reactive to monoclonal antibody 2, with matching sequence type to a patient isolate. An electronic control system turned off cooling tower pumps during low-demand periods, preventing delivery of disinfectant by a timed-release system, and leading to amplification of Legionella in the cooling tower. Guidelines for tower maintenance should address optimal disinfection when using automated systems.
