A company who had two products recalled last month following the detection of listeria monocytogenes has resumed production after tackling the cause of the issue.

A statement from McCormack Family Farms reveals that the presence of listeria in an irrigation pipe led to the issue.

On July 27, several spinach and mixed leaves products produced by the company were recalled.

The statement released by the company said its product testing flagged the presence of listeria monocytogenes in a batch of its produce, leading to the immediate recall of the products from the supply chain.

The statement continued: “We then carried out an extensive investigation to identify the source of the problem so that corrective action could be taken. 

"Well over 100 samples were taken by ourselves and DAFM (Department of Agriculture) and tested in an independent laboratory. This included all food contact surfaces, all batches of products in stock, and every piece of packing and harvesting equipment.” 

While initial tests revealed no presence of listeria, further investigations “led us to the irrigation pipe we only used to water the crop in question”.

The statement elaborated: “Once tested, it returned a positive result for listeria. This happened despite a recent significant investment in irrigation system upgrades, including a UV treatment plant. 

We fully understand that the recall has caused concern. We pride our family business on the quality of our produce and take utmost care when it comes to health and safety. 

The company says it had “already went above and beyond the minimal requirement when it comes to food safety standards,” but added: “We have now added extra measures to enhance food safety even further.” 

The company now takes daily lab testing of product samples, it says. Enhanced maintenance and cleaning procedures for irrigation equipment has also been introduced.

The company added: “Our production is now back in full swing and your safety remains our number one priority. We sincerely apologise to our customers for the concern caused, and we are very grateful for the support received in navigating this difficult time.” 

Earlier this month, production also recommenced at Ballymaguire Foods following an “extensive” outbreak of listeriosis which had led to the recall of prepared meals — including cottage pies, lasagnes, pasta bakes, curries and potato side dishes.
