| Kit used: | Type of kit used: | ||||||||||||||||
| Additional information: | DSP in mussels on suspended rope culture at all depths. Maximum toxicity Rat bioassay (+++) Mouse bioassay (+++). Okadaic acid (max 201 ug/100g total mussel meat) in all samples tested. DTX1 (max 25ug/100g total mussel meat) in four of the samples detected by M. Hageltorn, Sweden using HPLC. | ||||||||||||||||
| Economic losses: | |||||||||||||||||
| Management decision: | No human illness due to early detection. Early onset and protracted closures caused trade disruption. Fortunately most areas cleared before significant losses of stock. | ||||||||||||||||
| Additional harmful effect information: | Onset of toxicity about six weeks earlier than in previous years. Distribution and toxin levels very similar to 1987 event. | ||||||||||||||||
