New Zealand – Paralyitic Shellfish Poisoning Alert – PSP

New Zealand HeraldMarlith

At least seven people have been poisoned by eating shellfish in the Bay of Plenty, prompting warnings from health officials.

In a 24 hour-period over the weekend, five people went to Rotorua Hospital with symptoms of toxic shellfish poisoning with a further two unrelated cases were seen at Tauranga Hospital.

All of those who had fallen ill had eaten shellfish collected from the coastline between Mount Maunganui and Papamoa. Their symptoms ranged from tingling round the mouth and face, tingling of the skin on their arms and hands, mild weakness when walking, and diarrhoea and vomiting.

Australia – PSP Botany Bay – Sydney

News Com AU

A TOXIC algal bloom which potentially poisons a range of seafood has been detected in Sydney’s Botany Bay.

The NSW Department of Primary Industries said it had detected a species of algae which produces paralytic shellfish poisoning toxins.

It said it found toxins above safe levels for human consumption in shellfish from Botany Bay during routine monitoring on Friday.

The NSW Food Authority has warned people against eating oysters, mussels, cockles, clams or the gut of rock lobster or abalone taken from the bay or the Georges River.

Australia – Tasmanian Scallops PSP and Unsafe Poultry

AFNSalmonella Campylobacter

The Food Safety Information Council has released concerning national survey data this week that shows 60% of home cooks in Australia are putting themselves at additional risk of food poisoning from chicken.

The data showed that 60 per cent were at risk from washing whole poultry before it was cooked, which can spread bacteria around the kitchen. A further 16% of those surveyed incorrectly tasted chicken to see if it was cooked properly rather than using a safe meat thermometer.

The focus on cross-contamination of meats by the Food Safety Information Council (FSIC) comes as yesterday marked the start of Australian Food Safety Week. The FSIC week is specifically focusing on chicken and those most affected by food poisoning with the theme “vulnerable populations.”

Food Safety Information Council Chairman, Dr Michael Eyles said that chicken, as Australia’s most popular meat, was consumed by 8 in every ten home cooks.

”Home cooks are probably following what their parents or grandparents did in the past by washing poultry, not to mention probably patting it dry with a tea towel. Washing poultry splashes these bacteria around the kitchen cross contaminating sinks, taps, your hands, utensils, chopping boards and foods that aren’t going to be cooked like salads or desserts,” Dr Eyles said.

“Chicken is a healthy, convenient meal [but] other poultry is also becoming popular with just under half of those surveyed cooking whole turkey and 37% whole duck but these, too, are being washed before cooking, with 68% washing turkey and 74% duck,” he added.

According to a Food Standards Australia New Zealand survey referenced by the Food Safety Information Council, 84 per cent of raw chicken carcasses tested positive to the food poisoning bacteria Campylobacter and 22 per cent to Salmonella.

SCALLOPS from the east coast of Tasmania have joined the area’s mussels in being banned following a toxic algal bloom.

A scallop fishery in the White Rock area has been closed after the same paralytic shellfish toxin (PST) found in Spring Bay Seafood’s mussels was detected in samples taken on November 2.

“PST levels in tested scallops are currently either close to or slightly over the permitted level, but it’s possible the level will increase before it goes back down again,” a health department warning said.

The affected shellfish don’t look or taste different and the toxin is not destroyed by cooking or freezing, but there have been no reports of illness.

USA – Updated Warning About Shellfish – PSP

Food Poisoning Bulletin

The California Department of Public Healthis adding sport-harvested clams and whole scallops to the list of Del Norte County bivalve shellfish that consumers should avoid. This warning is in addition to the annual mussel quarantine that was extended on October 31, 2012 to include Del Norte and Humboldt counties. The shellfish contain dangerous levels of paralytic shellfish poisoning toxins (PSP).

The warning does not apply to commercially sold clams, mussels, scallops, or oysters from approved sources. These shellfish are subject to frequent mandatory testing by the state government.

PSP toxins affect the central nervous system, producing a tingling around the mouth and fingertips. Then, symptoms include a loss of balance, loss of muscular coordination, slurred speech, and difficulty swallowing. These symptoms can appear within a few minutes to a few hours after eating the toxic shellfish. In some cases, complete muscular paralysis and death from asphyxiation can occur. Cooking does not destroy the toxin. For more information, see the CDPH Marine Biotoxins Frequently Asked Questions page

Canada – Advisory Alert Shellfish Vibro parahaemolyticus

CDC BC 

The BC Centre for Disease Control is reminding the public there’s a risk of illness associated with eating raw or undercooked bivalve shellfish such as oysters, clams, mussels, scallops, and cockles.

 Shellfish may accumulate bacteria(Vibrio parahaemolyticus), viruses (norovirus, hepatitis A), and toxins (paralytic shellfish poisoning, diarrhetic shellfish poisoning) or other impurities present in the water. Thorough cooking destroys bacteria and viruses, but does not destroy toxins.

 To date in 2012, five cases of locally-acquired Vibrio parahaemolyticus infection have been reported. In 2011, 42 cases of vibrio were reported. These illnesses have been linked to raw shellfish served in restaurants, bought at retail, or self-harvested in communities throughout the province including, Gibsons, Sechelt, Powell River, Ladysmith, Qualicum, Ucluelet, Gabriola Island, Cortes Island and Parksville.

In addition to individual cases, BC has also experienced outbreaks associated with shellfish. In 2010, an outbreak of norovirus from raw oysters affected over 30 people and in 2011 more than 60 people became ill after consuming cooked mussels contaminated with diarrhetic shellfish poisoning.

Oyster Bay Shellfish – Vibrio parahaemolyticus Outbreak

Food Poisoning Bulletin

The New York Department of Environmental conservation is advising food establishments to avoid using or selling shellfish harvested from areas in the town of Oyster Bay, N.Y. According to the Rhode Island Department of Health, harvesting is no longer allowed in that area because of an illness outbreak caused by Vibrio parahaemolyticus, a naturally occurring marine bacteria.

FSA – Move Away from Animal Testing for PSP

FSA

The Food Standards Agency’s shellfish monitoring programme has successfully completed a move away from tests using mice for the detection of paralytic shellfish poisoning (PSP) and lipophilic toxins in commercially harvested shellfish.

The phasing out of animal testing in the shellfish monitoring programme has been a long-term goal of the FSA. Without an approved alternative method available, tests on mice had previously been the most suitable way of detecting toxins in shellfish. However, the FSA and Cefas (Centre for Environment, Fisheries, and Aquaculture Science) have spent a number of years developing alternative testing methods that do not rely on mice.

Andrew Wadge, Chief Scientist at the Food Standards Agency, said: ‘This is a significant milestone in meeting the UK’s commitment to reduce the burden of animal testing and has been achieved after years of FSA-funded research.

‘PSP and lipophilic toxins can cause severe illness if people consume them, so it is important that our shellfish monitoring programme is as effective as possible at detecting them. In order to meet our commitment, we have had to ensure suitable alternative methods are introduced in all our statutory biotoxin testing.
