EU project offers fresh perspective on climate change and food safety

The global fresh produce supply chain must take into account climate change in order to ensure food safety, warn EU-funded researchers.

This was the key recommendation of the EU-funded VEG-I-TRADE project, which was launched in 2010 to assess the safety of fresh produce in a rapidly evolving context of climate change and expanding international trade.

‘Global warming is often associated with challenges concerning food security – the production of sufficient food to feed the world,’ says project coordinator Mieke Uyttendaele from Ghent University, Belgium. ‘However, the potential impact on food safety is often overlooked.’

VEG-I-TRADE studies revealed that the microbial ecology of plants is influenced by a web of complex interactions between climate, environment, biological, technical and cultural factors. A shift in one of the factors can lead to changes to the whole web, potentially impacting the safety of fresh produce.

A major outcome of the project has been a series of recommendations and findings that national competent authorities, industry associations and private companies can use to reinforce their own guidelines, or to carry out adaptation scenarios with the aim of taking the safety of fresh produce to the next level.

The project’s wide geographical coverage was central to its success. In addition to a wide variety of European partners, VEG-I-TRADE involved entities in Brazil, Egypt, India and South Africa.

‘Overall, VEG-I-TRADE successfully enhanced dialogue and created a multidisciplinary network of professionals that will be sustained through ongoing international collaborations,’ says Uyttendaele. ‘Some of our outcomes are now available as e-learning modules for local and global training programmes.’

The partners used field samples and a self-assessment tool to track the status of best practices and management systems implemented at primary production, processing or trade level. ‘The pros and cons of various water treatment technologies for example were documented. In addition to water management, other key areas included personal hygiene, documentation and record keeping, storage and transport,’ says Uyttendaele.

While all partners involved in the project conducted similar studies, their work explored very different settings. “People grow fresh produce in every country. But aspects such as the climate, the workforce or the regulatory framework differ,”Uyttendaele notes. In Brazil, for example, lettuce and tomatoes are usually supplied by small-scale farmers, she explains, whereas Europe tends to source such produce from big agricultural businesses. The country’s warm, humid conditions, which are highly conducive to the growth of pathogens, mean that local farmers face particular challenges with regard to food safety.

The results of the project’s supplier survey were recently published. Key issues included the need to pursue water recycling strategies, which should be carried out without compromising food safety. Regulatory standards and certification were seen as both a catalyst for best practice and a non-tariff barrier to trade, with the need for science-based assessment highlighted.

From the overall VEG-I-TRADE results database, it was also notable that elevated levels of E. coli increased the likelihood of detecting pathogenic bacteria such as Salmonella. However the occurrence and levels of E. coli in irrigation water and harvested produce varied, depending on local circumstances. ‘While setting E. coli indicator threshold values to alert producers can be useful, the project recommends that these should be set taking into account the local circumstances,’ says Uyttendaele.

While VEG-I-TRADE was officially completed in April 2014, the positive impact of the project on fresh produce safety is likely to be long-lasting. Members of the consortium contributed to the drafting of European Food Safety Authority (EFSA) Opinions in 2013 and 2014 on the risk posed by pathogens in foods of non-animal origin, along with revised Codes of Practice for fresh produce at the global Food and Agriculture Organization of the United Nations (FAO)/World Health Organisation (WHO) Codex Alimentarius level. Project partners have also contributed to new EU recommendations currently in the pipeline on ensuring hygiene and safety in fresh produce production.
