Serranidae and Labridae fish caught in 1993 at Alijos Rocks, 300 miles off East Magdalena Bay, Southern Baja California, caused severe illness of a fishing boat crew. The described symptoms resembled those of ciguatera. The presence of ciguatera-like toxins was confirmed on extracts from these fish using the mouse bioassay procedure, showing activities between 220 to 390 mouse units (M.U.). The founding of ciguatoxin at Alijos Rocks 24 degrees 57' N, 115 degrees 45' W) extends to the northeast its geographical distribution in the Pacific and locates the outbreak near the continental coastline.
1993年在南下加利福尼亚州南部马格达莱纳湾以东300英里处的阿利霍斯岩捕获的鮨科和隆头鱼科鱼类，导致一艘渔船船员患上重病。所描述的症状类似雪卡毒素中毒。使用小鼠生物测定程序在这些鱼的提取物中证实了雪卡毒素样毒素的存在，活性在220至390小鼠单位（M.U.）之间。在北纬24度57分、西经115度45分的阿利霍斯岩发现雪卡毒素，将其在太平洋的地理分布扩展到东北部，并确定了靠近大陆海岸线的疫情发生地。
