The Drinking Water Treatment Partnership Project addresses the need for clean drinking water in low-income mobile home parks located throughout Eastern Coachella Valley, CA. This project funds and oversees the installation of water treatment systems (reverse osmosis units) that reduce arsenic and fluoride levels in the drinking water to safe levels. Other jurisdictions can make a difference similarly by working with local groups and non-profits that can address the need to remedy water quality issues for small water systems.

Abstract

This study evaluated whether a difference existed between one-hour and one-day notice on inspection announcements versus unannounced inspections on health inspection ratings of food establishments. Three hundred food establishments were randomly assigned into three sections of no announcement, one-hour announcement, or one-day announcement. Certified food inspectors performed routine inspections of these establishments for foodborne illness risk factors. Inspection results were analyzed using chi-square analysis. A significant interaction was found: those who had no notice were more likely to have an unsatisfactory outcome (4%) than establishments that had either one-hour or one-day notice (0%). One-hour notice did not result in a significant difference in outcome when compared with no notification. One-day notice did result in a significant difference in outcome when compared with no notification. This result suggests that one-hour notification is not a significant amount of time to impact the outcome of an inspection, but is sufficient to allow management to logistically prepare for an inspection and still maintain the objective of the inspection process.

On January 9, 2014, an estimated 10,000 gallons of industrial chemical 4-Methylcyclohexanemethanol (MCHM) spilled into the Elk River in Kanawha County, West Virginia, contaminating the water and subsequently resulting in the shutdown of the municipal water system. While it resulted in an extraordinary inter-disciplinary public health response, the West Virginia water crisis received national and global attention. Come discuss the concerns this incident raised about national water security and the effectiveness of public health infrastructure to handle large emergencies.

In recent years, nitrogen in the environment has become a nationwide concern due to the sensitivity of many water bodies to excess nitrogen loading from many different sources, including Onsite Wastewater Systems (OWS). This session will kick off an afternoon of sessions that highlight recent research sponsored by the Florida Department of Health which is being used to develop strategies to manage and reduce nitrogen loading from OWS and to protect groundwater and surface waters.

The food truck phenomenon has gained national media attention with an estimated 20,000 plus trucks nationwide bringing in over $1.2 billion annually. Amid the frenzy is a host of unique challenges for food safety professionals. This session addresses many approaches to the operational obstacles associated with food trucks such as operating in a small space, reliance upon generators to keep food at correct temperatures, limited water supply, and their mobile nature. Be prepared to take away tips and tricks to use in your work to prevent foodborne illness with food truck operators.

Abstract

Following the “fetal origins of adult disease” hypothesis, environmental determinants of birth weight regained interest. The authors applied a detailed spatial-time exposure model for climatological factors thought to affect fetal growth: seasonality, temperature, and sunshine. Daily climatological data (29 stations) were linked to 1,460,401 term births with an individual exposure matrix for each pregnancy. Linear regression was utilized to determine effects of climatological factors on individual birth weight and existing spatial variations in birth weight. In the Netherlands substantial regional climatological differences exist. Summer was associated with significantly reduced birth weight (16–19 g). Minimum and maximum temperatures were significantly associated with increased and reduced birth weight, respectively. Spatial birth weight differences ranged from -11 to +25 g, with lowest birth weights in inland areas. The authors demonstrate birth weight to be associated with climatological factors; negative birth weight effects of maximum temperature exposure confirm results from animal studies. Consequently, a climate footprint is visible in the spatial birth weight differences.

Abstract

In 2012, the Wicomico County Health Department began investigating groundwater contamination in the Morris Mill community. The contamination was due to high levels of trichloroethylene (TCE). TCE is a colorless nonflammable liquid that has a sweet odor and a burning taste. Exposures can lead to acute effects as well as more chronic conditions such as cancer. A total of 300 wells were sampled during the course of the investigation. Fifty wells showed levels of TCE above the maximum contaminant level of 5 parts per billion. Timely communication with the residents and risk management played integral parts in assisting the community towards a long-term solution. In December 2013, the Wicomico County Urban Services Commission created an urban service district to provide public water from the city of Fruitland to the entire affected area. Completion of the water tower and distribution system for the 273 affected homes was expected in early 2016.

Abstract

Bed bugs continue to affect society and place a burden on public health systems. Experiences of the Let’s Beat the Bug! campaign are presented to help information networks prepare personnel to effectively address questions about this pest. Following recommendations from the Minnesota state bed bug working group, an information line was established and the Web site (www.bedbugs.umn.edu) was revised. Data from both services were analyzed by geographic region and type of information requested. InformationLine primarily assisted people who had issues dealing with failed treatments and landlord reluctance to take effective measures against this pest. Web site visits indicated a preference for learning do-it-yourself control methods. There were commonalities in the information sought from both services. People were often looking for reassurance, in addition to information about basic prevention and control of bed bugs. We present here priority topics that public health personnel should be prepared to answer if they receive inquiries about bed bugs.
