France blames Lactalis, retailers in deepening baby food scare

France, seeking to limit reputational damage to its agri-business industry, threatened on Thursday the past week to impose sanctions after the country’s big supermarkets said recalled baby foods made by Lactalis had still found their way onto shop shelves.

The admissions deepened a salmonella health scare that began in early December when France’s consumer protection agency ordered the halt to sales and a global recall of products from a factory in northwest France. Three dozen children have fallen ill.

Privately-held Lactalis, which has annual sales of around 17 billion euros ($20 billion), addressed the salmonella contamination by halting operations at the factory where it started, and announced the temporary layoff of 250 workers. 

The recall included products aimed for export to some 30 countries, including to China, and overall represented more than 12 million baby food tins  was the biggest recall Lactalis had ever experienced.

Study: Salmonella detection in powdered dairy products using a novel molecular tool

In the study by Yueming Zhao et al. at Key Laboratory of Dairy Science,  Northeast Agricultural University, Harbin China, the team developed a rapid, specific, and sensitive loop-mediated isothermal amplification technique combined with a lateral flow dipstick (LAMP-LFD) method to detect Salmonella targeting the siiA gene in powdered infant formula (PIF).

The results showed that the method of LAMP-LFD had a high diagnostic specificity of 100% for detection of Salmonella in PIF.

The results verified that the method of LAMP-LFD targeting the siiA gene is rapid, accurate, and sensitive for Salmonella detection in PIF, and that PMA shows great potential to be widely used to eliminate the amplicon contamination risk generated by the highly sensitive LAMP reaction in the detection process.
