Production is resuming today at Ballymaguire Foods following a suspension last month after the detection of the harmful bacteria listeria at one of its facilities.
The company said it has received approval from the National Environmental Health Service of the Health Service Executive (HSE) to recommence production.
In a statement it added "this follows a comprehensive process undertaken in close coordination with the HSE's Environmental Health Officers and the Food Safety Authority of Ireland (FSAI)".
It said the products it makes will return to supermarket shelves from next Tuesday (12 August).
Last month, more than 200 products made by the company were subject to a food safety recall due to fears of listeria monocytogenes.
This included products from Tesco Finest, The Happy Pear, SuperValu Signature Taste, and Centra Freshly Prepared.
The various branded prepared meals and side dishes are sold in most major supermarkets - including Aldi, Centra, SuperValu, and Tesco - and are branded under the names of its customers.
Ballymaguire Foods appointed Professor Patrick Wall, a public health expert and former chief executive of the FSAI, to lead its response to the situation.
Professor 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.
"In response to this incident, Ballymaguire Foods has implemented protocols that go beyond best practice, fully align with regulatory standards, and set a benchmark that exceeds industry norms.
"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. The decision to grant approval for production to resume reflects the authorities’ confidence in the steps taken," he added.
Consumers are advised not to eat any of the more than 200 affected products, and are also advised to check their fridges and freezers for the implicated products and dispose of them.
Symptoms of Listeria monocytogenes infection can include mild flu-like symptoms, or gastrointestinal symptoms such as nausea, vomiting and diarrhoea.
In rare cases, the infection can be more severe, causing serious complications.
Some people are more vulnerable to Listeria monocytogenes infections, including pregnant women, babies, and people with weakened immune systems, including the elderly.
The incubation period (time between initial infection and first symptoms appearing) is on average three weeks but can range between three to 70 days.
