What is changing in food shopping – and what consumers in the region should pay attention to

Those who shop in Bayreuth and Upper Franconia will have to prepare for changes in the coming months and years. New rules in European food law are intended to simplify procedures, enable innovation and secure supply. For consumers, this means less bureaucracy in the background, but new questions when shopping. Prof. Dr. Kai Purnhagen, an expert in food law from Bayreuth, draws attention to this.

"Food remains safe," emphasises Purnhagen. "But the way information is communicated and products are regulated is changing." One of the most visible changes could concern labelling. In recent years, the number of voluntary seals and labels has grown significantly – with limited benefit for consumers. "Studies show that too many labels tend to confuse rather than help," says Purnhagen. "Labels mainly sell a good feeling, regardless of what they actually say." For consumers, this means that key information such as allergens or health-related information will remain. At the same time, it will become more important not to rely solely on eye-catching seals. 

New techniques, familiar foods

Genetically modified organisms (GMOs) continue to be a particularly sensitive topic of discussion. At EU level, there are plans to treat new genomic techniques differently from traditional genetic engineering in legal terms. Certain procedures will be possible in future without authorisation or labelling. "This may sound new to many people, but it isn't," explains Purnhagen. "Many foods that we have been eating for decades are genetically modified without being labelled." It is important to differentiate: processes involving profound genetic modifications should continue to be regulated and labelled. Scientifically, there is no evidence of a higher risk with the new, more precise techniques – but socially, the issue remains controversial. 

Testing innovation – without risk to everyday life

The new rules are supplemented by so-called real-world laboratories. There, new foods and production processes can be tested under controlled conditions. "This does not affect normal shopping," says Purnhagen. "These tests take place within a clearly defined framework." The aim is to keep innovation in Europe and at the same time gain experience before new products are launched more widely on the market. 

Keeping an eye on prices and availability 

Import controls will also play a greater role in the future. Food from third countries will be subject to stricter checks to ensure European standards are met. Why? "This protects consumers and regional producers," says Purnhagen. "At the same time, it can have an impact on prices and availability." Especially in times of global supply chains, security of supply remains a key issue – also for everyday shopping. 

Guidance instead of uncertainty

Purnhagen's conclusion: consumers need not be alarmed, but should remain vigilant. "Food law regulates our everyday lives more than many people realise," he says. "Those who understand why things are changing can make informed decisions – instead of being unsettled by headlines."

Prof. Dr. Kai Purnhagen, a renowned expert in the field of international food law at the University of Bayreuth, has held Germany's first professorship in food law since 1 July 2000. He teaches at Faculty 7 (Life Sciences) at the Kulmbach campus. Purnhagen is also chairman of the Ethics Committee at the University of Bayreuth and, together with Prof. Dr. Markus Möstl, director of the Research Centre for German and European Food Law.
