A nonprofit, independent media organization dedicated to telling stories of climate solutions and a just future. Phyllis Clough was driving to the post office in the tiny Alaskan village of Old Harbor one summer afternoon when her lips went numb. Within minutes, her mouth was swollen and the numbness had spread to the rest of her face. She learned how close she had come to catastrophe at the local clinic the next day.

Type Accommodation and the title of the report in the subject line of e-mail. In collaboration with local partners, SOE investigated and identified a total of eight confirmed and 13 probable PSP cases that occurred during May--June Warnings to avoid noncommercially harvested shellfish were broadcast on local radio and television and displayed at beaches and in post offices, government offices, and businesses throughout the region.
Commercially harvested shellfish, which are tested for the presence of PSP-causing toxins, were safe. Because the risk for PSP is unpredictable, persons who consume noncommercially harvested Alaskan shellfish should know that they are Alaska roulette dating risk for PSP, and suspected cases should be reported promptly to SOE to initiate control measures in the affected area.
On June 3,a man aged 52 years residing in Metlakatla, on Annette Island in southeast Alaska, awoke from a nap with numbness around his mouth, tingling in his hands, and slight dyspnea. He was taken to the Annette Island Service Unit, the community's health center, where a clinician inquired about recent seafood consumption. After the man reported eating a meal of steamed cockles shortly before his nap, the clinician diagnosed PSP. The man was transported to Ketchikan where, having become weak and unable to sit up in bed without assistance, he was admitted to the intensive-care unit. PSP primarily from ingestion of saxitoxins, toxins produced by marine dinoflagellate algae that accumulate in bivalve mollusks e.
PSP is a potentially fatal neuroparalytic condition. s and symptoms of PSP range from mild, short-lived paresthesias of the mouth or extremities to severe, life-threatening paralysis 1. Because PSP is such a serious condition and because a case indicates widespread risk to the shellfish-consuming population of the affected area, immediate reporting of PSP cases to SOE by health-care providers is mandatory in Alaska.
That afternoon, two SOE epidemiologists traveled to Metlakatla population: 1, persons to investigate. The epidemiologists met with a visiting public health nurse onsite and conducted active case finding by broadcasting messages Alaska roulette dating local television and radio and through word-of-mouth among community members.
For this investigation, a probable case of PSP was defined as a compatible illness, including paresthesias, in a person shortly after consumption of noncommercially harvested shellfish from Alaska waters during spring SOE identified an additional 12 probable cases in Metlakatla and used a structured questionnaire for patient interviews.
The team collected shellfish from two beaches where shellfish associated with PSP had been harvested. They also collected frozen cockles from a community member who harvested them with the index patient patient A before that patient became ill. While conducting the investigation in Metlakatla, SOE was notified of two men working in Ketchikan population: 8, persons who had been examined in the hospital's emergency department on June 8 and subsequently were admitted with symptoms consistent with PSP, including paresthesias patients F and G.
Both patients were severely ill; one had required intubation and assisted ventilation and was admitted to the intensive-care unit. The men had shared a meal of boiled, noncommercially harvested mussels. The hospital shipped leftover mussels brought in by the men to the Alaska Department of Environmental Conservation's Environmental Health Laboratory.
Urine specimens from the two hospitalized men and two persons who had accompanied them to the hospital and had eaten the same meal of mussels, but who had no symptoms themselves, were sent to CDC for analysis 2. SOE requests that clinicians collect the first available urine, freeze it immediately, and ship as soon as possible.
While at the hospital in Ketchikan, the epidemiologists were informed of two additional patients who had been examined in the emergency department in May and who had been diagnosed with shellfish allergies but who had symptoms consistent with PSP hours after consuming a clam and cockle chowder. Active case finding in Ketchikan identified Alaska roulette dating additional probable cases. Overall, eight probable and five confirmed PSP cases were identified in Metlakatla, and five probable and two confirmed cases of PSP were identified in Ketchikan during this outbreak.
All 21 patients reported experiencing paresthesias, with incubation periods for all cases ranging from 0 to 3. Four of the cases were reported to SOE, one after a delay of 3 days.
The cockles collected from the community member in Metlakatla and the mussels collected from the hospital in Ketchikan tested positive for high levels of saxitoxins Table. Joseph B.

However, this was not the first time an increase occurred in the annual of PSP cases in Alaska 3. Active case finding during this outbreak enabled epidemiologists to identify persons with PSP symptoms who had not sought care and thus would never have been reported. This demonstrates that the overall burden of PSP in Alaska likely is underestimated through standard reporting. However, saxitoxin levels were reported to have been higher in shellfish in the region during spring than in years Kate Sullivan, University of Alaska Southeast, personal communication,indicating that the increase in the of cases might not have been a surveillance artifact.
PSP is a preventable condition. Avoidance of noncommercially harvested Alaskan shellfish not tested for saxitoxins is the best way to prevent PSP. Because shellfish harvesting is an important cultural tradition and shellfish are an important subsistence Alaska roulette dating source for many Alaska Natives and other Alaska residents, not everyone follows the public health recommendation to avoid eating shellfish from noncommercial sources.
Furthermore, transient fish-processing workers Alaska roulette dating Alaska might be unaware of the potential danger of eating untested Alaskan shellfish because they are unfamiliar with PSP and might have limited English literacy. During the investigation, SOE epidemiologists posted s at beaches on Metlakatla and within the community to warn residents about the PSP risks associated with consuming noncommercially harvested shellfish. Additionally, the Alaska Department of Health and Social Services issued press releases and conducted media interviews to inform the public about the outbreak and the need to avoid noncommercial harvesting of shellfish.
No additional cases of PSP have been reported in Alaska since this investigation. Because Alaskan shellfish can have high levels of PSP saxitoxins at any time of year and neither cooking nor freezing destroys the toxin, development of a widely available, inexpensive, and easy-to-use test kit to measure toxin concentrations in noncommercial shellfish would be beneficial. Symptoms of PSP occur within minutes to hours of shellfish consumption 1and because the course of the illness is unpredictable, immediate medical assessment is strongly recommended.
The roles of state and local governments, clinicians, and community leaders include 1 identifying cases so that investigations and control measures e. Clinicians should report suspected cases of PSP to local health authorities immediately and promptly collect and freeze samples of patient urine and any uneaten shellfish for PSP toxin testing. Martinek, Barbara J. Smith, and Eileen L. Paralytic shellfish poisoning PSP is a potentially fatal yet preventable condition that from ingestion of saxitoxins, a family of neurotoxins produced in certain marine algae and sometimes found in bivalve mollusks.
PSP is considered a rare condition and is reportable in Alaska.
Public health authorities should respond immediately to suspected cases of PSP so that warnings can be provided to the community. Enhanced surveillance during public health responses might increase the of cases identified, allowing better characterization of the Alaska roulette dating of the problem.
Effective public information campaigns on the risks of noncommercially harvested shellfish and the need to seek medical care if symptoms of PSP develop are an important public health practice in PSP-affected regions.
