USA – Certain Dungeness crabs recalled because of poisoning risk -Domoic Acid – Amnesic Shellfish Poisoning

Food Safety News

The Quinault Tribe of the Northwestern United States is voluntarily recalling almost 58,000 pounds of live or un-eviscerated Dungeness crab because of possible domoic acid contamination, which can cause amnesic shellfish poisoning in people. 

With Dungeness crab being a popular New Year’s dish, public health officials in Washing state posted the recall notice today in hopes of reaching holiday cooks before meals are prepared. It is not clear how far the crab may have been distributed.

Domoic acid is a naturally occurring toxin produced by certain types of algae and can be harmful to humans if contaminated shellfish is consumed. 

Domoic acid can cause amnesic shellfish poisoning (ASP) with symptoms including vomiting, nausea, diarrhea, and abdominal cramps within 24 hours of ingestion. In severe cases, ASP can cause permanent short-term memory loss.

Oman – Dhofar Governorate records multiple food poisoning cases

Times of Oman

Dhofar Governorate recorded several food poisoning incidences due to eating some seashells that were affected by the red tide phenomenon

The Ministry of Health (MOH) said, “A number of health institutions in Dhofar Governorate have registered several food poisoning incidences as a result of consuming seashells that contained poisonous substances as the beaches were affected due to the red tide phenomenon.”

“In such cases, the infected person may suffer from various symptoms such as vomiting, diarrhoea, symptoms related to the nervous system like numbness, weakened movement and shortness of breath,” the ministry added.

Therefore, MOH urges fishermen and consumers to avoid eating fishes and seashells coming from the areas affected by the red tide. It has also called upon all to stay away from the areas that suspected to be affected by the red tide phenomenon to avoid poisoning.

Norway – The inspection program for shellfish 2019

Mattilsynet

Shells along the Norwegian coast have low concentrations of E. coli, heavy metals and other undesirable substances. It shows the results from the annual monitoring of bacteria and environmental toxins in mussels from production areas and mussel samples taken in connection with the Norwegian Food Safety Authority’s mussel warning.

What did we investigate? Mussels, scallops, flat oysters, Pacific oysters, cow mussels, O-mussels, carpet mussels, king snails and Drøbakkråkebolle.
Period: 2019
What were we looking for? E. coli, Salmonella and the environmental toxins cadmium, mercury, dioxins and dioxin-like PCBs, as well as polyaromatic hydrocarbons.
What did we find? About 90 percent of all submitted mussels were below the limit of E. coli and there were no detections of Salmonella. A total of 453 E. coli samples and 26 salmonella samples were analyzed.

Mussels: All examined mussels were below the limits for environmental toxins.

Scallops: No excesses of environmental toxins in muscle and gonads. Flat oysters: Cadmium was detected above the limit value in two samples.

O-shells and king snails: The heavy metal cadmium was, as in previous years, proven well above the limit value. The majority of heavy metals, such as cadmium and lead, have previously been localized to the kidneys. The Norwegian Food Safety Authority therefore recommends that the kidneys be removed before consumption, so that edible parts fall well below the limit values.

New Zealand – Shellfish biotoxin alert – Northland west coast

MPI

The Ministry for Primary Industries today issued a public health warning against collecting shellfish on the Northland west coast from Waipapakauri on 90 Mile Beach, south to Pouto Point on the northern head of the Kaipara Harbour. This includes the Herekino, Whangape and Hokianga Harbours. Warning signs will be posted in the coming days.

Another warning remains in place for the west coast of the North Island – from South Head (Manukau Harbour entrance) to Tirua Point (south of Kawhia).

Routine tests on shellfish samples taken from these regions have shown levels of Paralytic Shellfish Poisoning (PSP) toxins above the safe limit of 0.8 mg/kg set by MPI. Anyone eating shellfish from this area is potentially at risk of illness.

Mussels, oysters, tuatua, pipi, toheroa, cockles, scallops, catseyes, kina (sea urchin) and all other bivalve shellfish should not be eaten.

Note, cooking shellfish does not remove the toxin.

Pāua, crab and crayfish may still be eaten if the gut has been completely removed prior to cooking, as toxins accumulate in the gut. If the gut is not removed its contents could contaminate the meat during the cooking process.

Symptoms typically appear between 10 minutes and 3 hours after ingestion and may include:

  • numbness and a tingling (prickly feeling) around the mouth, face, and extremities (hands and feet)
  • difficulty swallowing or breathing
  • dizziness
  • headache
  • nausea
  • vomiting
  • diarrhoea
  • paralysis and respiratory failure and in severe cases, death.

If anyone becomes ill after eating shellfish from an area where a public health warning has been issued, phone Healthline for advice on 0800 61 11 16, or seek medical attention immediately. You are also advised to contact your nearest public health unit and keep any leftover shellfish in case it can be tested.

Monitoring of toxin levels will continue and any changes will be communicated accordingly. Commercially harvested shellfish – sold in shops and supermarkets, or exported – is subject to strict water and flesh monitoring programmes by MPI to ensure they are safe to eat.

Caribbean – CPS reports cases of fish poisoning

The Daily Herald

PHILIPSBURG–The Collective Prevention Service (CPS), as a public health agency, is advising the public to pay attention to proper food handling procedures when preparing meals.

CPS said the department had received reports of four cases of fish poisoning September 5 and 7.

“As with all reportable diseases, CPS surveillance nurses conduct case follow-up to identify the possible source(s) of exposure,” CPS said on Thursday. During the investigation, it came to light that the purchasing, storage, and preparation of the seafood played a major role in the source of food poisoning.

“CPS would like to remind persons when purchasing fish, or any type of sea food, that it is important to handle the products safely to reduce the risk of foodborne illness often called food poisoning,” said the department.

Paralytic shellfish toxins are a group of natural toxins that sometimes accumulate in bivalve shellfish that include oysters, clams, scallops, mussels and cockles. Non-bivalve shellfish, such as whelks, can also accumulate PSP toxins. These toxins can cause PSP if consumed. Symptoms of PSP include tingling and numbness of the lips, tongue, hands and feet, and difficulty swallowing with an onset of a few minutes and up to 10 hours after consumption. In severe situations, this can proceed to difficulty walking, muscle paralysis, respiratory paralysis and death.

New Brunswick health officials have declared an outbreak of vibrio parahaemolyticus, a bacteria found in shellfish that causes gastrointestinal illness in humans.

The province says nine cases of vibrio have been confirmed. The average for New Brunswick is typically only two to three cases a year.

“I am advising all New Brunswickers to ensure that they obtain shellfish and other seafood from a licensed establishment or harvest shellfish from fishing zones which are currently open by Fisheries and Oceans Canada,” said N.B. chief of health Dr. Jennifer Russell in a news release.
