The provincial Department of Health has instructed local authorities to strengthen public awareness campaigns and urge residents not to collect, cook or consume wild mushrooms unless their safety can be clearly identified.
High humidity during the rainy season encourages the growth of many mushroom species, increasing the risk of poisoning among residents and tourists who forage for wild mushrooms.
Residents have also been advised to seek immediate medical attention if they develop symptoms such as vomiting, abdominal pain or diarrhoea after eating mushrooms.
Local governments have been asked to strengthen monitoring and coordinate with health agencies in responding to poisoning cases.
According to local authorities, more than 300 mushroom species grow in Dalat's pine forests and surrounding areas during the rainy season, including around 50 species of the highly toxic Amanita genus.
Many poisonous mushrooms resemble edible varieties, making them difficult to distinguish without specialist knowledge.
The warning follows several recent poisoning cases. Earlier this month, four members of the same family in Dalat were hospitalised after eating wild mushrooms collected from a forest, some of whom required prolonged treatment.
