Cyclospora – August 18, 2015

A recent surge in reports of illnesses due to the parasite Cyclospora has prompted DSHS to investigate the infections in hopes of determining a common source. DSHS has received reports of 243 Cyclosporiasis cases from around Texas this year. Past outbreaks have been associated with cilantro from the Puebla area of Mexico. While the investigation into the current outbreak is ongoing, DSHS has identified imported cilantro as a possible source of some infections.

Cyclosporiasis is an intestinal illness caused by consuming food or water contaminated with the Cyclospora parasite. The major symptom is watery diarrhea lasting a few days to a few months. Additional symptoms may include loss of appetite, fatigue, weight loss, abdominal cramps, bloating, increased gas, nausea, vomiting and a low fever. People who think they may have a Cyclospora infection should contact their health care provider.

DSHS recommends thoroughly washing fresh produce, but that may not entirely eliminate the risk because Cyclospora can be difficult to wash off. Cooking will kill the parasite.

Last year, Texas had 200 cases, some of which were associated with cilantro from the Puebla region in Mexico.

West Nile in Texas – September 1, 2015

DSHS is reminding people about the danger posed by West Nile illness and encouraging people to protect themselves. People should reduce their risk of exposure to the mosquito-borne virus that causes it by eliminating standing water and other mosquito breeding areas; making sure door, porch and window screens are in good condition; wearing long sleeves and long pants outdoors when possible and using an insect repellent that contains DEET, picaridin, IR3535, or oil of lemon eucalyptus/para-menthane-diol.

As many as 80 percent of people who contract the virus will have no symptoms at all. Almost all others will have West Nile fever with symptoms like headache, fever, muscle and joint aches, nausea and fatigue. A very small minority will develop West Nile neuroinvasive disease, a life threatening illness that can cause neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness and paralysis.

One case in 2015 has resulted in death. In 2014, there were 379 human cases of West Nile illness in Texas, including six deaths.

Chikungunya – September 1, 2015

Chikungunya is a viral illness causes fever and severe joint pain and is transmitted by mosquitoes. All reported cases in Texas cases have been imported, meaning that travelers have acquired the illness while visiting parts of the world where the virus is more common. However, those imported cases mean there is a potential for chikungunya to spread in Texas because the Aedes mosquitoes that transmit it are present in the state.

Blue Bell Update – May 14, 2015

DSHS has finalized a plan with Blue Bell requiring the company to take specific steps before it can sell ice cream to the public. Among the list of requirements, Blue Bell must conduct trial runs of each production line that consistently test negative for Listeria monocytogenes before ice cream from those lines can be sold. The company will also test ice cream, ingredients and equipment for Listeria and let state health inspectors review all results.

Agreement between DSHS and Blue Bell

Blue Bell Creameries previously recalled all products and stopped producing ice cream following the discovery of the bacteria Listeria monocytogenes in certain ice cream products.

Ten past cases of listeriosis (Kansas, 5; Texas, 3; Arizona, 1; Oklahoma, 1) recently have been associated with Blue Bell products. The Texas cases identified as part of the outbreak are related to products made at the company’s Oklahoma plant. The Texas cases were hospitalized for unrelated problems before they developed Listeriosis between 2011 and 2014. The Kansas cases were identified and linked to products from the company’s Brenham plant.

Listeriosis is an infection caused by eating food contaminated with Listeria monocytogenes. The illness primarily affects older adults, pregnant women and people with weakened immune systems. Symptoms usually start within several days, though they can develop up to two months after eating contaminated food. Symptoms may include diarrhea or other gastrointestinal symptoms followed by fever or muscle aches.
