Plant-Based RTE Products, Salmonella in Eggs and Dairy Consolidation

New findings on food safety, traceability and the European dairy market

A European survey provides detailed microbiological data on ready-to-eat plant-based alternatives. A new Salmonella report shows how WGS and traceability reveal recurring weaknesses in an egg supply chain. Meanwhile, Lactalis plans to acquire Saputo’s entire UK dairy business.

Plant-based RTE alternatives: a positive overall picture, with clear process signals

A prevalence study published by the European Food Safety Authority, coordinated with 15 Member States, examines microbiological contamination in ready-to-eat plant-based milk, meat and fish alternatives at the end of their shelf life [1]. For Germany, the Federal Institute for Risk Assessment has analysed the results of 104 samples from retail, wholesale and online sales [2].

Neither Listeria monocytogenes, Salmonella nor Clostridium perfringens was detected in this German subset. Instead, the findings revealed distinct process and hygiene signals: Bacillus cereus sensu lato was found in 37 of 104 samples, with substantially higher detection rates in cheese, meat and fish alternatives than in milk alternatives. Counts were generally low; two cheese alternatives reached 2,100 and 3,000 CFU/g respectively. All isolates examined carried genes for the Nhe enterotoxin complex. The isolate from the most heavily contaminated sample also carried the ces gene cluster associated with cereulide [2].

Two fermented cashew-based soft cheese alternatives also contained elevated levels of non-specific E. coli. Listeria innocua occurred in three samples, one at 3,100 CFU/g. A positive stx2 PCR signal in a UHT milk alternative could not be confirmed by culture and therefore remains a presumptive finding [2].

The product groups are not microbiologically interchangeable

The pH and water activity (aW) values published in the BfR project show why a single release approach for ‘plant-based RTE products’ is inadequate. These are group statistics, not limits for individual formulations. The BfR summary provides no separate pH or aW statistics for cream alternatives, so the study cannot provide a reliable individual value for this category.

The figures are group statistics, not limits for individual formulations. *The BfR summary reports a mean and median aW of 0.95 jointly for meat, fish and cheese alternatives; it does not provide separate aW values for these three categories. Neither pH nor aW is reported separately for cream alternatives.

Bacillus cereus sensu lato should therefore be regarded as the study’s principal target organism: a spore-forming, potentially toxin-producing organism, rather than a typical spoilage organism in the narrower sense. L. innocua is primarily a hygiene and environmental indicator of possible Listeria persistence; E. coli points to a hygienically significant process or recontamination gap. The study did not examine typical spoilage flora such as yeasts, moulds or specifically those lactic acid bacteria relevant to sensory quality. The data therefore do not establish a reliable spoilage pattern.

These findings do not support a blanket risk judgement on plant-based alternatives in product development. What matters is the combination of matrix, pH, aW, fermentation, heat treatment, cold chain and recontamination routes, together with changes through to the end of shelf life. The cheese alternatives with higher counts particularly demonstrate that a lower pH alone cannot replace product release assessment. For manufacturers, product-specific process limits, shelf-life data and risk-based testing for spore-formers and hygiene indicators are therefore more informative than an undifferentiated category assessment [2].

Following up on the WGS framework: the egg supply chain reveals a persistent Salmonella gap

On 7 August, Food Essentials discussed the new European requirements for submitting WGS data on foodborne outbreaks [3]. An EFSA report published on 11 August now provides a concrete follow-up case: four geographically separate outbreaks involving Salmonella Enteritidis ST11 were investigated in France between May and July 2026. Epidemiological and microbiological findings pointed to home-made egg-based products; five food isolates from eggs or egg products matched two representative human strains [4].

Traceback linked all outbreaks to a shared distribution network involving two packing centres and three laying-hen farms belonging to the same Polish corporate group. These farms had previously been linked to a multinational, polyclonal egg-associated outbreak affecting 18 countries from 2016 to 2020. EFSA considers the renewed detections an indication of possible persistence or reintroduction of contamination in primary production; the underlying cause remains unresolved. Genomic clusters containing human and non-human isolates from France and other countries also indicate a potential cross-border connection, without yet demonstrating specific involvement in Germany, Austria or Switzerland [4].

The case demonstrates the operational value of genomic resolution: despite the low genetic diversity within S. Enteritidis ST11, two outbreak strains could be distinguished and linked to the supply chain. For egg processors and manufacturers of egg-based products, the focus therefore shifts from batch release alone to whether supplier assessments, strain histories, packing-centre and farm data, and root-cause analyses are brought together over several years. Recurring clusters within a previously identified network require a different regulatory and crisis-management assessment from an isolated positive finding. However, the report replaces neither the outstanding root-cause investigation nor company-specific evidence of particular contamination routes.

Lactalis and Saputo UK: five plants and a brand portfolio set to change hands

On 14 August, Saputo announced a binding agreement to sell its entire UK dairy business to Lactalis subsidiary B.S.A. SAS. The stated enterprise value is approximately £988 million. The transaction includes five manufacturing sites and brands such as Cathedral City, Wensleydale, Davidstow, Clover and Country Life. According to the company, the UK division generated approximately C$1.2 billion in revenue over the past four quarters, representing around seven per cent of Saputo’s group revenue [5].

Completion is expected by the end of the first quarter of 2027, subject to customary conditions and regulatory approvals. Until then, the acquisition has not been completed. Saputo attributes the decision to a sharper portfolio focus and the release of capital; the announcement contains no statements about the buyer’s future site, sourcing or brand strategy [5].

For the European dairy market, the transaction nevertheless represents more than a change of ownership. An integrated portfolio of established cheese and spread brands, together with five plants, would come under the management of an already diversified European dairy group. No definite immediate changes can yet be identified for raw-material suppliers, co-manufacturing partners or private-label customers. Once the transaction is approved, however, sourcing consolidation, capacity allocation and the distinction between branded and private-label business will be the key areas to monitor.

Wishing you a good week, Andreas Gebhart
