Speaking at the Hybu Cig Cymru – Meat Promotion Wales (HCC) annual conference, Griffiths reinforced the work being done within the Welsh Assembly to support the industry, which she claimed would be hit hard with ongoing uncertainty around a departure date.
“Exiting the EU without a deal would have an immediate and catastrophic effect on our rural communities,” she said.
“I’m confident the Welsh Government has done and will continue to mitigate against the prospect of a no-deal.
“We're doing all we can maintain sustainability during the ongoing beef price fluctuation. Price fluctuations relating to the exit date are particularly disrupting to farm businesses and it is for this reason we introduced the BPS Scheme.
“It will provide short-term cash certainty to businesses and I urge you to submit an application by 29 November.”
Failure to do so could have long-term implications for many producers in the region, she added.
The BPS Scheme provides a loan to help farmers who may not receive their BPS 2019 payment when the payment window opens on 1 December 2019.
The BPS Scheme payment value would be a maximum of 90% of their estimated 2019 BPS payment.
Her call came as HCC announced a new push to promote the sustainability and health benefits of Welsh meat.
