New Zealand – Updated – Shellfish biotoxin alert issued for parts of Bay of Islands

MPI 

The Ministry for Primary Industries today issued a public health warning against collecting shellfish in the Bay of Islands, extending to the outer heads between Cape Wiwiki and Cape Brett.

Routine tests on shellfish samples taken from the Bay of Islands region 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.

MPI also strongly advises the public against collecting shellfish in the Hawke’s Bay region due to concerning levels of toxins being detected in shellfish. A warning is also in place for the Kenepuru and Pelorus Sounds.

Mussels, oysters, tuatua, pipi, toheroa, cockles, scallops, cat’s eyes, 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.

Signs will be erected in the affected areas.

The Ministry for Primary Industries (MPI) today issued a public health warning against collecting shellfish in the Kenepuru Sound and inner Pelorus Sound, extending outward to Tawero Point and Opani-aputa Point.

Routine tests on shellfish samples taken from this region 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, cat’s eyes, kina (sea urchin) and all other bivalve shellfish should not be eaten.

RASFF Alert – Paralytic Shellfish Poisoning (PSP) toxins in chilled live mussles

RASFF-Paralytic Shellfish Poisoning (PSP) toxins (1178 µg/kg – ppb) in chilled live mussles (Mytilus edilus) from Norway

Canadian Recalls – Tahina – Salmonella – Raw Shellfish – PSP

C

Ottawa, August 16, 2013 – The Canadian Food Inspection Agency (CFIA) is warning the public, food service establishments, and retailers, not to consume, serve, use, or sell the tahina products described in the link above because they may be contaminated with Salmonella.

Some of the affected product was sold in bulk and may have been repacked at retail.  Consumers who cannot determine the original product identity are advised to check with their retailer to determine if they have one of the affected products.

There have been no reported illnesses associated with the consumption of these products.

The CFIA is working with the Canadian importers to remove all affected products from the market place.  The CFIA is monitoring the effectiveness of the recall.

All Tahina products, manufactured by Al Nakhil Co, of Lebanon between September 5, 2012 and April 21, 2013, are affected by this alert.

CFIA

Ottawa, August 16, 2013 – The Canadian Food Inspection Agency (CFIA) is warning the public not to serve or consume the raw shellfish products described in the link above because they may contain paralytic shellfish toxins that can cause illness if consumed.

These shellfish products were primarily distributed to wholesalers and institutional clients such as restaurants. However, the affected shellfish products may also have been sold in smaller quantities at some retail seafood counters. Consumers who are unsure whether they have the affected products are advised to check with their retailer or supplier.

These products have been distributed in Alberta and British Columbia.  However, they may have been distributed in other provinces and territories.

There have been no reported cases of Paralytic Shellfish Poisoning (PSP) associated with the consumption of these products.

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. In severe situations, this can proceed to difficulty walking, muscle paralysis, respiratory paralysis and death in as quickly as 12 hours.

The shellfish processors are voluntarily recalling the affected products from the marketplace. The CFIA is monitoring the effectiveness of the recall.

USA – Consumers Warned About Shellfish PSP

Food Poisoning Bulletin

The California Department of Public Health (CDPH) is warning consumers not to eat recreationally harvested mussels, clams, or whole scallops from Marin County. Dangerous levels of paralytic shellfish poisoning (PSP) toxins have been found in mussels in this region. These naturally occurring toxins can cause illness or death. Cooking does not destroy this toxin.

This warning is in addition to the annual mussel quarantine that was extended on October 31, 2012 for Del Norte and Humboldt counties. That quarantine is still in effect.
