Muscat: Tons of potatoes have been destroyed in Oman after a ministerial circular warned about contamination with solanine, a naturally occurring toxic material in potatoes.

The seized potatoes were exposed to heat and not stored well, according to the Ministry of Regional Municipalities and Water Resources (MRWWR).

Solanine is a glycoalkaloid poison found in species of nightshade family like potato and tomato. It occurs naturally in the plant, its leaves and fruits. Solanine consumption causes gastrointestinal and neurological disorders.

Symptoms include nausea, diarrhoea, vomiting, stomach cramps, burning of the throat, cardiac dysrhythmia, nightmares, headache and dizziness.

An official at MRWWR told Gulf News that thorough inspection will be conducted in other provinces and wholesales markets to ensure safety of the consumers.

The official said random potato samples from shops will be tested in the main laboratories nationwide before further action is taken. The official said there were no reports of anyone affected or poisoned from the consumption of potato.

In Buraimi, more than 200kg of potatoes were dumped by Buraimi Municipality after they were found to contain solanine.

The Directorate General of Regional Municipality and Water Resources in the Governorate of Al Buraimi and Dhofar called upon citizens and expatriates not to buy potatoes that are dominated by green colour as they are dangerous to health.
