Ballymaguire Foods has received approval from the HSE's National Environmental Health Service to recommence production.

Ballymaguire Foods said this follows a "comprehensive process undertaken in close coordination with the HSE’s environmental health officers and the Food Safety Authority of Ireland (FSAI)".

Production will resume from today (Friday, August 8), with products returning to retail shelves from Tuesday (August 12).

Official approval to resume production follows the completion of a "thorough review" into the recent detection of Listeria at one of its production sites, Ballymaguire Foods said.

In July, Ballymaguire Foods confirmed it had temporarily suspended all production at one of its facilities as a "precautionary measure" following a recall of various branded prepared meals and side dishes.

The FSAI had issued recall notices on various Ballymaguire Foods products "due to the possible presence of Listeria monocytogenes".

Ballymaguire Foods subsequently appointed Professor Patrick Wall, a public health expert and former chief executive of the FSAI, "to lead our response, which was carried out in close collaboration with all relevant public health and regulatory authorities", the company said.

Professor Patrick Wall said: “Listeria is a naturally occurring, complex, and challenging bacteria that, while rare, requires close attention and strong controls in food environments. 

"Managing it is not just about routine hygiene—it requires a deep understanding of how it behaves and an unrelenting attention to detail.

“The actions taken are backed by substantial investment and reflect a renewed focus on precision, accountability, and continuous improvement throughout the organisation.

"Every measure is grounded in international best practice and scientific evidence, with a focus on maintaining the highest standards of food hygiene and consumer health protection."

Professor Wall said that the decision to grant approval for production to resume "reflects the authorities’ confidence in the steps taken".

“While Listeria infection is rare and primarily affects individuals with weakened immune systems, such as the elderly or those undergoing medical treatment, even low-probability risks must be managed with the utmost seriousness," he added.

"The steps taken at Ballymaguire Foods reflect a genuine commitment to protecting every consumer, and to doing so with transparency and integrity.”

Edward Spellman, co-founder and managing director of Ballymaguire Foods, said: “Our team worked closely with public health authorities and independent experts throughout this review, and I want to acknowledge their support, rigour, and professionalism.

“Food safety has always been central to who we are. This experience has challenged us to go even further—to enhance our systems, deepen our expertise, and apply new industry-leading standards.

“We acknowledge the concern this situation has caused. We are resolute in our commitment to learn from it and to strengthening the trust placed in us by our partners, customers, and consumers.”
