Suphoj Maythaphirat, a senior official, said Night Safari animal keepers were partly at fault for not screening the feed bought from villagers, adding that elephants should not eat too much old grass in a single sitting.
Phang Joi and Phang Grandma died late last month after succumbing to extremely bad digestion, while three other elephants are recovering from the same symptoms. Suphoj said only soft grass will be fed to the ill elephants. They will also be given more water to drink.
Suphoj said insecticide in the grass - bought regularly from three communities in Tambon Mae Hia, Suthep and Nong Khwai - could be a reason for the deaths and that tests were currently underway.
