Thiruvananthapuram: At least 400 CRPF jawans posted at the Pallipuram unit in the capital city suburbs were taken ill reportedly due to food poisoning on Saturday.

While 200 of them have been admitted at the Medical College hospital, the rest have been admitted at a hospital near the unit.

"The condition of four was a bit serious when they arrived here, but they have quickly responded to the treatment," the hospital superintendent said.

Sources added that those who consumed fish during dinner complained of nausea, vomiting and an upset stomach.

The preliminary treatment having been administered, they are now under observation.

A helpline number -- 0475-2528647 -- has been established at the Thiruvananthapuram medical college as well.
