Thai health authorities have issued a nationwide health warning following confirmed outbreaks of anthrax and Streptococcus suis, a bacterial disease locally known as “deafness fever,” both linked to the handling and consumption of raw or undercooked meat.
In Mukdahan province, three cases of anthrax have been identified, according to reports from the Pattaya Mail. One patient has died, while two others remain hospitalised. Authorities have traced 636 individuals who came into contact with the infected, of whom 538 have already completed a week of symptom monitoring. The remaining 98 are under active observation and receiving prophylactic treatment with Doxycycline.
Anthrax, caused by Bacillus anthracis, typically infects humans through contact with infected animals or contaminated soil. It is not contagious between humans, but its spores are highly resilient, capable of surviving in the environment for decades. Officials have urged the public to strictly avoid raw or undercooked meat and to consume only properly cooked beef.
Separately, in Phrae province, a surge in Streptococcus suis infections has resulted in 14 confirmed cases and at least two deaths. The disease, colloquially called “deafness fever,” can cause permanent hearing loss if untreated. It has been linked to the consumption of traditional raw pork dishes, most notably larb moo, a spicy minced pork salad commonly served in northern Thailand.
Public Health Minister Somsak Thepsuthin stated that most patients had recently eaten raw pork. “Prompt treatment is crucial, as Streptococcus suis infection can cause permanent hearing loss if it is left untreated,” he said in an official advisory.
The ministry has activated inter-agency coordination to contain both outbreaks and maintain public confidence. Surveillance has been intensified in affected provinces, with regular updates promised as investigations continue.
Citizens are being urged to prioritise food safety by avoiding raw meat, using protective gear when handling animal products, and seeking immediate medical care if symptoms such as fever or muscle pain occur.
