Confirmation from two samples is still pending with the final results expected on Tuesday evening.
According to Satamaito, the bacteria have also not been found by the health authorities after they tested surface samples and products manufactured before the suspension of production.
On Wednesday last week, the company pulled products from the shelves and suspended production as spot test conducted indicated the presence of listeria growth.
According to Jarmo Oksman, the CEO of the company, the culture method is a more reliable way of identifying listeria compared to spot test.
Satamaito will launch intense cleansing at its diary plant at the beginning of the week and afterwards it begins production test runs.
