Health Director-General Datuk Dr Noor Hisham said that this took the tally to 61 cases with two deaths so far.
"The new cases were recorded in Kedah (14 cases), Perak (seven) and Selangor (21), where all were reported to have suffered similar symptoms. The findings showed that symptomatic patients had consumed the laksa sold at the premises in Kupang," he said.
He said 21 patients has been warded, while 38 others received outpatient treatment.
Dr Noor Hisham said the Kedah State Health Department had conducted a detailed examination of the premises that sold the laksa, and found that it had no relation to reports of contaminated Iceberg Lettuce gone viral on social media recently.
He said the Health Ministry was still awaiting the results of food samples sent to the lab, adding that stool samples of patients tested positive for 'Salmonella spp'.
