Government departments have collected 194 tonnes of palm stearin since it was spilled last week.
Three-hundred staff from the Marine Department, the Leisure & Cultural Services Department, the Food & Environmental Hygiene Department, the Agriculture, Fisheries & Conservation Department and the Environmental Protection Department have been conducting daily beach inspections and cleanups.
They have reported gradual improvement in conditions on beaches and in coastal areas.
The oil content of water samples collected from beaches has remained at a low level.
For the five beaches reopened yesterday, the LCSD reminded swimmers to rinse their feet before entering changing rooms to avoid slipping on any palm stearin.
The departments will continue to monitor the situation and enhance cleanup work to reopen beaches as soon as possible.
