Public health officials in Nakhon Ratchasima have confirmed 13 deaths linked to Streptococcus suis infection, locally known as “ear fever”, with 93 cumulative cases recorded in the province. The outbreak has prompted urgent health warnings ahead of New Year celebrations due to increased social gatherings involving food preparation and consumption. Authorities have stressed that improper handling or consumption of pork poses a serious and potentially fatal risk.

On 31 December, Dr Wicharn Khithen, Nakhon Ratchasima Provincial Public Health Officer, issued a public warning via the official Facebook page of the Provincial Public Health Office. He stated that Nakhon Ratchasima currently ranks first nationwide for reported cases of the disease. Data from the Communicable Disease Control Group show that between 1 January and 30 December 2025, a total of 93 cases were recorded, resulting in 13 deaths.

Streptococcus suis is a bacterium found in the respiratory tract and blood of infected pigs. Humans can contract the disease through two main routes: consuming raw or undercooked pork or pork blood and direct contact with infected pork, offal, or blood through open wounds, scratches, or the eyes. Symptoms typically appear within 1 to 14 days and include high fever, severe headache, dizziness leading to loss of balance, vomiting, and neck stiffness.

Health officials noted that some patients became ill or died after eating raw or partially cooked pork, often referred to locally as “raw pork fever” or “ear fever”. Other high-risk foods include raw blood larb, raw koi dishes and raw fermented pork products such as nem moo. Cooks or food handlers with cuts who handle raw pork or blood are also at risk of infection.

The Provincial Public Health Office has emphasised preventive measures during the year-end and New Year holiday period welcoming 2026. Officials advised the public to avoid eating raw or undercooked pork, blood, or offal at all times. They also urged the separation of kitchen equipment, such as knives and chopping boards, used for raw pork and vegetables.

Consumers have been advised to purchase pork only from certified and standardised outlets. Those eating pork barbecue or similar meals should use separate chopsticks or utensils for handling raw meat and cooked food. People working directly with pigs are advised to bathe and thoroughly clean their bodies immediately after completing work.

ThaiRath reported that Public health authorities will continue monitoring cases and reinforcing food safety messaging. Officials have urged the public to seek immediate medical attention if symptoms occur after pork consumption or contact. Continued vigilance is expected throughout the festive period.
