This comes after rumours that Dawn Meats will be taking over the Northern Irish-based meat processor, although this has not been confirmed.
In his letter, Edwards (pictured) said he wanted to raise concerns regarding job losses within his constituency. "I am advised that up to 10 jobs have recently been lost at the plant." The MP was first notified of the job losses by a constituent who wished to remain anonymous.
"There is speculation in the industry media that Dawn Meats are at the final stages of a takeover purchase of the Dunbia group, which includes the aforementioned abattoir," he said.
"The Dunbia plant is a major employer in Llanybydder. I am concerned regarding further job losses and the impact this will have on the local economy. My understanding from speaking to employees at Llanybydder is that, following the takeover, Dawn Meats may centralise the retail department of Llanybydder at their Crosshands plant. The retail department is the most labour-intensive section of the abattoir. It is of the upmost importance to me that jobs at the plant are safeguarded and kept in Llanybydder."
He concluded by requesting information of the implications a possible merger could have on food processing in Carmarthenshire and on the Welsh government food processing strategy.
Dunbia said that it would not be commenting on this matter. A response from the Welsh government is also awaited.
It was previously rumoured in the summer of 2016 that 2 Sisters would be acquiring Dunbia, although these talks were later dispelled.
Dunbia began life in 1976 as a butcher's shop, previously called Dungannon Meats.
