Outbreak News Today Legionella_Plate_01

Three people have been diagnosed with Legionnaires’ disease and one person has died following stays at the Christmas Mountain Resort in Wisconsin Dell. At this time, the local health authorities are investigating the outbreak.

As the investigation unfolds, a representative for the resort told the local media that some of their accommodations did indeed have Legionella present. “After testing, we found that the water supply in certain units had been affected and, subsequently, tested positive for the bacteria,” the spokeswoman said. The resort claims to be telling prospective guests about the disease, but thus far denies that the confirmed illnesses occurred on their property – despite the fact that all of those who are ill stayed at the resort within 2 weeks of their illnesses.

USA – New Dates For Implementing Agricultural Water Produce Safety

Food Poisoning Bulletin Eurofins Food Testing UK

FDA’s Commissioner Dr. Scott Gottlieb and Deputy Commissioner Frank Yiannas have addressed advancing new tools and science for produce safety via agricultural water, and have set new dates for implementation. The two E. coli O157:H7 outbreaks that were linked to romaine lettuce in 2018 were allegedly caused by contaminated agricultural water.

USA – Campylobacter Outbreak in 2017 Associated with Well Water Supply in Nebraska

Food Poisoning Bulletin

The February 22, 2019 issue of the CDC’s Morbidity and Morftality Weekly Report had a study about a Campylobacter outbreak in 2017 that was associated with the municipal water supply in Nebraska. At least 39 people were sickened after they drank untreated city water. The city was not named, just called “City A.”

Apparently, a center pivot irrigation system, that was supposed to pump livestock waste into farmland malfunctioned. Runoff collected in a road ditch near two wells that fed the water supply.

There were 33 probable and 6 confirmed cases in this outbreak. Untreated unboiled city A tap water was the only exposure that was significantly associated with illness.

The city is served by four untreated wells and an interconnected distribution system. After the wells were removed from service, no further illnesses were reported.

In March 2017, the Nebraska Department of Health and Human Services (NDHHS) and the Southwest Nebraska Public Health Department were notified of an apparent cluster of Campylobacter jejuni infections in city A and initiated an investigation. Overall, 39 cases were investigated, including six confirmed and 33 probable. Untreated, unboiled city A tap water (i.e., well water) was the only exposure significantly associated with illness (odds ratio [OR] = 7.84; 95% confidence interval [CI] = 1.69–36.36). City A is served by four untreated wells and an interconnected distribution system. Onsite investigations identified that a center pivot irrigation system intended to pump livestock wastewater from a nearby concentrated animal feeding operation onto adjacent farmland had malfunctioned, allowing excessive runoff to collect in a road ditch near two wells that supplied water to the city. These wells were promptly removed from service, after which no subsequent cases occurred. This coordinated response rapidly identified an important risk to city A’s municipal water supply and provided the evidence needed to decommission the affected wells, with plans to build a new well to safely serve this community.

Two people in Waco have been diagnosed with Legionnaires’ disease after using a local YMCA’s hot tub. The Waco-McClennan County Health District is investigating the Waco Family YMCA located at 6800 Harvey Rd., Waco, Texas. The hot tub is expected to be closed for the next few weeks, while the water undergoes testing for Legionella bacteria.

Rodney Martin, CEO of YMCA of Central Texas, stated, “Exposure to the Legionella bacteria may have occurred at the Waco Family YMCA.  Hot tubs specifically are a potential source and in both instances there was exposure in the hot tub area.”

USA – Legionnaires’ disease cluster reported in Brooke County, WV

Outbreak News Today legionellac

Brooke County, WV health officials report investigating a cluster of six Legionnaires’ disease cases. At this time, there is no link to any of the cases as a common source or location.

Legionellosis is a bacterial disease of the lungs caused by Legionella pneumophila. The disease can range from a mild respiratory illness to severe pneumonia and death. The most common form of legionellosis is known as “Legionnaires’ disease,” named after an outbreak in 1976 when many people who attended an American Legion conference in Philadelphia became ill.

Most people contract the disease by inhaling mist or vapour from a water source contaminated with the bacteria.   The disease is not contracted by drinking contaminated water, and person-to-person spread of legionellosis does not occur.
