The best worth was above 180,000/100-g in flat oysters. The 33 samples analyzed for Salmonella had been all destructive.
One other 282 samples had been despatched to the institute instantly by trade. Of those, E. coli was above 230/100-g in 37 samples, 36 of blue mussels and one in every of sea vases, the place the very best worth was 3,500/100-g in two samples of blue mussels.
One pattern of flat oysters exceeded most ranges, with the cadmium focus above the higher restrict of 1 mg/kg moist weight at 1.3 mg/kg moist weight. One pattern of horse mussels was above most lead and cadmium ranges.
