Between October 2007 and March 2008, local authorities in the UK collected samples of ready-to-eat seeds as part of the LACORS / HPA coordinated microbiological sampling programme. The final report from this study is now available:

Ready to eat seeds report

The study focused on ready-to-eat dried seeds from retail premises. The microbiological safety of samples was assessed in relation to Salmonella contamination and levels of Escherichia coli, an indicator of faecal contamination.

Key findings:
• 3735 samples of ready-to-eat dried seeds were collected from 3390 retail premises in the UK. 
• Salmonella was detected in 23 samples (0.6%).
• Of the samples contaminated with Salmonella, over half were sesame seeds (57%). Other seeds contaminated with Salmonella were linseed (0.4%), sunflower (0.1%), alfalfa (1.7%), melon (8.5%) and mixed seeds (0.9%). 
• Escherichia coli was detected in 9% of samples, with 1.5% containing unsatisfactory levels (≥ 102 /g). 
• The UK retailers affected by the detection of Salmonella in their products publicly recalled the contaminated batches. Food Standard Agency food alerts were issued, advising consumers not to eat the affected products.

This study highlights the need for good hygiene practices and effective decontamination procedures during the production of these products.
