USA – Legionnaires’ Disease Outbreak Linked to Christmas Mountain Resort

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 – 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.

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 cases linked to Crookston, MN hotel

Minnesota health officials report investigating four recent cases of Legionnaires’ disease associated with a Crookston area hotel.

Four people who became ill between Jan. 22 and Jan. 27 all reported spending some time at the Crookston Inn and Convention Center prior to their illnesses. None of the ill people were overnight guests at the hotel, but all visited the hotel for various occasions.

USA – Illinois: Another Legionnaires’ disease cluster reported

Outbreak News Today

 

legionellacIn a follow-up to the recent Legionnaires’ disease clusters in Illinois, state and county health officials are investigating a cluster of three cases at McHenry Villa, an independent senior living community.

Public health officials confirmed the third case this week. McHenry Villa is notifying residents, the residents’ identified contact, and staff.  All three cases had outside exposures, and two of the cases had potential exposures at Centegra Hospital-McHenry.  Public health officials will continue to investigate any other potential sources.

Information – How Many Legionella Species Exist & Which Ones Cause Legionnaires’ Disease?

Legionella Control Legionella A

While there are more than 50 different recognised Legionella species, less than half of those can cause illness in humans. However, while around 20 species are known to be harmful to us, just one has been identified as the cause of most outbreaks of Legionnaires’ disease. Read further at the link above.

Information – How Temperature Influences Legionella Growth

Legionella Control Legionella_Plate_01

In this review the experts at Legionella Control International look at how water temperatures influence legionella growth and how this information can be used to control the risks from the bacteria.

Under certain circumstances Legionella bacteria can lead to serious illness and fatalities in humans. Since Legionella bacteria can exist in man-made water systems, it is imperative to ensure the water is stored, maintained and distributed at temperatures that do not encourage the growth and spread of the bacteria.

There are three temperature ranges that have an influence on the growth and proliferation of Legionella bacteria. Read at the link below.

Research – Traveler’s diarrhoea: Researchers develop 3-in-1 vaccine

Outbreak News Today 

 

A first-ever vaccine designed to deliver a one-two-three punch against the main causes of traveller’s diarrhea worldwide may result from new research published by a University of Guelph chemist.

Prof. Mario Monteiro says his novel three-in-one approach to developing a new vaccine could also save lives in developing countries, where it’s estimated that these three common pathogens kill more than 100,000 children under age five each year.

His research was recently published in the journal Vaccine.

The paper discusses Monteiro’s so-called conjugate vaccine that yokes together proteins from pathogenic E. coli with sugars from Shigella and Campylobacter jejuni. All three bugs are major causes of bacterial diarrhea globally.

USA – Flooding from Hurricane Michael creates food safety issues across South

Food Safety News

Strong winds and heavy rain continue to wreak havoc across parts of the South today as Hurricane Michael meanders out of Georgia and heads up the mid-Atlantic Coast.

In addition to the devastating damage that is immediately visible today, less obvious hazards in the wake of the massive storm are expected to last weeks. Food safety dangers come in various forms and can cause severe illnesses and deaths as floodwaters recede.

Among the most vulnerable foods are fresh fruits and vegetables. They are breeding grounds for pathogens when power outages cause the loss of refrigeration and temperature control. Fresh produce that comes into contact with floodwater can be instantly contaminated with a wide range of bacteria, viruses and parasites.

The toxic composition of floodwater is such a serious food safety hazard that federal law prohibits the sale, distribution or donation of any produce or other food crops from fields that are flooded. Special inspections are required before such crops can even be used for animal feed. 

USA Today

Hurricane Michael leaves behind a treacherous, dangerous landscape that will likely pose risks to human health for weeks to come, experts say.

The water itself can carry bacteria and viruses that pose a major health hazard.

Among the medical dangers are cholera, Hepatitis A and vibriosis, said Dr. Robert Glatter, an emergency room physician at Lenox Hill Hospital in New York City. Glatter said storm victims need to stay focused on staying healthy while they await recovery efforts. That may mean not rushing outside as soon as the skies clear.

“Don’t panic— try to take things one step at a time when you feel overwhelmed,” he said.
