Oh fishy-fishy, you’re so delicious, but a food safety challenge

Seafood forms a part of a healthy diet. However, seafood can be contaminated with foodborne pathogens, resulting in disease outbreaks. Because people consume large amounts of seafood, such disease outbreaks are increasing worldwide. Seafood contamination is largely due to the naturally occurring phenomenon of biofilm formation.

fish.headsThe common seafood bacterial pathogens that form biofilms are Vibrio spp., Aeromonas hydrophila, Salmonella spp., and Listeria monocytogenes. As these organisms pose a global health threat, recent research has focused on elucidating methods to eliminate these biofilm-forming bacteria from seafood, thereby improving food hygiene. Therefore, we highlight recent advances in our understanding of the underlying molecular mechanisms of biofilm formation, the factors that regulate biofilm development and the role of quorum sensing and biofilm formation in the virulence of foodborne pathogens.

Currently, several novel methods have been successfully developed for controlling biofilms present in seafood. In this review, we also discuss the epidemiology of seafood-related diseases and the novel methods that could be used for future control of biofilm formation in seafood.

New Zealand closes online fish market

Bored suburbanites like to dabble in risk, and I never understood the term black market, other than it was offensive.

UnknownMinistry for Primary Industries (MPI) compliance officers today terminated an operation against four groups in Auckland who were selling seafood.

MPI compliance officers supported, by the NZ Police, executed search warrants on five South Auckland properties that were identified, from a Facebook page, selling seafood to the public.

MPI compliance officers are talking to ten people in relation to the operation. Investigations are continuing with a view to laying charges under the Fisheries Act.

MPI Compliance Director Dean Baigent says compliance officers learned that a Facebook page was being used for one-off sales of seafood in Auckland and that the page had more than 400 followers.

MPI has been monitoring these groups and has received numerous reports from the public of this illegal activity.

But what about listeria risks? FDA says fish consumption in large amount is the best food during pregnancy

Daughter 2-of-5 is pregnant with my second grandson (I’m old).

What I’ve found through all these pregnancies is the enormous amount of conflicting advice provided to the moms-to-be.

jaucelynn.pregnantIt’s stressful enough being pregnant (not that I would know) without having Dr.-this-that giving bogus advice.

The Westside Story (whatever that is) writes that conflicting research works have been done on the nutritional benefits of consuming large amounts of fish during pregnancy and after that. Some studies have shown that fish is among the best foods that a pregnant and breastfeeding mom needs to take for the benefit of her baby and her own. However, some other studies raised questions about fish consumption, citing that some fish could actually have an adverse impact on the brain development of a baby. According to the latest research by the U.S. Food and Drug Administration (FDA), fish is good and eating large amounts of it is even better.

Good for brain development

What these stories lack is the potential Listeria risk in any refrigerated ready-to-eat foods like smoked salmon.

My kid’s got a biology degree and we’ve talked about this.

There’s a significant risk difference between refrigerated ready-to-eat foods and whole fish cooked to 145F as measured by a tip-sensitive digital thermometer.

Thousands expected as 36-hour Sydney Fish Market seafood marathon begins

Sorenne and I will go shopping this morning because when I do, it’s last minute.

the-fishmongers-shopThe annual 36-hour orgy has begun at the Sydney Fish Market and we’ll be getting our own seafood first thing in Brisbane.

 “I think it’s the vibe during Christmas, the busyness, the rush, the excitement of it all. Everyone is in a good mood, it’s a good time of the year,” says seafood buyer Paul Papacosta, from Penrith Seafoods at Wetherill Park, and Sydney Fresh Seafoods at Manly and Potts Point.

“But quality becomes a bigger issue because there is so much volume going through, you have to keep your eyes on everything, you can’t let anything slip through.”

Dimitri Hari has been running around the Sydney Fish Market since he was two.

“My old man works in the industry, mum was in it, my aunties. I was thrown in and they couldn’t get me out. God knows they tried but I wouldn’t get out of the place,” says Hari who works for de Costi, one of the biggest players in the market.

“Seafood has definitely become a (Christmas) tradition. As each year goes by, Christmas tends to get bigger — a lot more prawns, a lot more oysters.

thermometer.fish.sep.11“People like to indulge with lobsters, there is that. Even though people might be doing their traditional roast, there is definitely a big seafood influence there.

Not so much in the UK, where the Food Standards Agency cracked down on Ades Limited in London for handling and packaging dried fish products and whole frozen African land snails in an unapproved establishment (this establishment is different to the one mentioned on product labels), under unsatisfactory hygiene conditions with a lack of traceability. Its existing approval has been revoked because of these issues.

Despite investigations by the enforcement authorities, it has not been possible to obtain the full distribution details or product traceability records for these products. 

Australia: Operation Trident targets illegal seafood trade

Consumers are being urged to avoid stolen seafood this Christmas, with enforcement officers on the beat to stop illegal seafood traders.

SUN0705N-Oyster7Department of Primary Industries (DPI) Acting Director Fisheries Compliance, Patrick Tully said Operation Trident is a multi-phase operation targeting the theft or illegal sale of oysters during this peak season.

“DPI fisheries officers will be on the beat – in the streets as well as out on the water to protect the valuable crops from illegal fishers,” Mr Tully said.

“Fisheries officers work in conjunction with the NSW Food Authority and NSW Police Force – and in consultation with NSW Farmers to target oyster theft.

“The operation includes covert surveillance and overt inspections up and down the NSW coast that aims to disrupt and dismantle a black market which is responsible for ripping off hard working oyster farmers.

“Operation Trident has been a key part of the NSW Government’s crackdown on black market seafood since 2007.”

NSW Food Authority CEO Polly Bennett said the black market oyster trade poses a health risk to consumers.

“Consumers are being urged to be our eyes and ear on the streets this Christmas,” Ms Bennett said.

“Illegal seafood is often stored in the backs of unrefrigerated trucks and we strongly advise against anyone consuming seafood if they don’t know where it’s come from.

“Stolen oysters might not come from an area covered by the NSW Shellfish Program, the NSW Food Authority recommends people only buy oysters from reputable retailers as these oysters have been monitored for their safety.”

NSW Police Force’s Marine Area Commander, Superintendent Mark Hutchings, said anyone illegally trading seafood should expect to be caught.

“Police have been working closely with DPI and NSW Food Authority to target and dismantle seafood trafficking rings that are ripping off our farmers and putting people’s health at risk,” Supt Hutchings said.

“We are calling on the community, particularly restaurant or café owners, who may be approached by someone offering cheap oysters to call Crime Stoppers on 1800 333 000 and help us stop this illegal and potentially dangerous trade.

“Remember, the number-one rule of a scam is that if the offer sounds too good to be true, it probably is.”

Members of the public and any affected oyster farmers are urged to call Crime Stoppers on 1800 333 000 if they have any information about oyster theft and the black market trade.

 

I have to recall? I sue you

On Dec. 12, 2012, Ocean Beauty Seafoods LLC voluntarily recalled 371 cases of ready-to-eat cold smoked salmon products because of possible contamination by Listeria monocytogenes.

goodfellasNow, they’re suing their supplier.

Ocean Beauty Seafoods is suing salmon farming giant Marine Harvest for damages the U.S. supplier states it sustained as a result of recalls of Listeria monocytogenes tainted smoked salmon at the end of 2012 and the start of 2013.

Seattle, Washington-based Ocean Beauty suffered nearly $2 million in damages due to the contaminated products and, despite multiple demands from Ocean Beauty, Marine Harvest has refused to compensate Ocean Beauty for its losses, according to the claim in the case, filed on July 11, 2014.

Starr Indemnity & Liability Company, an insurer for Ocean Beauty, has issued payment to Ocean Beauty for damage caused by the defendants, and joins the action to enforce its rights of subrogation against the defendants.

‘Get out of Ukraine’ G20 leaders enjoy lavish seafood BBQ

The G20 is over, Brisbane is slowly returning to normal, but it was Canadian PM Stephen Harper who stole the show when he met blame_canadaRussia’s Putin and said, “I guess I’ll shake your hand, but get out of Ukraine.”

The leaders were treated to a seafood BBQ featuring Moreton Bay bugs, Mooloolaba king prawns, shucked oysters (hopefully they were cooked), and Tasmanian ocean trout.

We had our own Tassie trout on Saturday.

Who steals seafood? New Yorkers

A thief stole a tractor-trailer holding more than $1,000 worth of seafood in Eastchester on Monday, according to the NYPD.

3392_1384449356Police are looking for the the maroon-colored Freightliner cab, license plate number F4475N, and trailer, plate number 0753CP, which were stolen while parked at the intersection of Pinkney and Hutchinson avenues at about 12:15 p.m. on Sept. 1, police said.

Concern over shellfish safety controls in Ireland

A “significant” number of recommendations involving shellfish food safety controls still have not been fully addressed, more than two years after they were made, a new audit by the European Commission’s Food and Veterinary Office has found.

Raw oystersThe latest audit on some Irish-produced shellfish, carried out last October, found that the control system in place for the production and placing on the market of bivalve molluscs, which includes blue mussels, pacific oysters, king scallops and razor clams, presented “several deficiencies”.

These were in the classification and monitoring of production areas and in the official control of scallops and gastropods, a category that includes whelks and periwinkles.

What about Listeria? Pregnant women advised to eat more fish

I was talking with daughter Braunwynn today about her future academic and travel plans. She also wanted to know my preferred way to cook pork chops.

But this is about fish, and as Braunwynn said when she was in Brisbane, “How can I go back after this?”

amy.pregnant.listeriaWe are fortunate in Brisbane to have a fabulous supply of seafood.

The U.S. Food and Drug Administration said women and children should eat more fish, but sidestepped the issue of raw or undercooked seafood for pregnant women.

It’d be nice for all the mothers out there, who are already inundated with contradictory messages, if FDA consolidated toxin and microbiological risk information into a cohesive message. For example, pregnant women shouldn’t be eating any refrigerated ready-to-eat seafood like salad or smoked salmon.

Liz Szabo of USA Today writes that federal officials for the first time are recommending that young children and pregnant or breastfeeding women eat a minimum of two to three servings a week of fish that is low in mercury, in order to give them important health benefits.

Current guidelines, released a decade ago, focused on limiting the amount of fish consumed by women who are pregnant or breastfeeding, due to concerns about contamination from methylmercury, which can cause brain damage, especially to developing brains, said Elizabeth Southerland of the Environmental Protection Agency, which released the new guidelines along with the Food and Drug Administration.

That advice apparently scared a lot of women into avoiding fish altogether. Research has shown that 21% of pregnant women ate no fish at all in the past month, said Stephen Ostroff, acting chief scientist at the FDA. Even among women who consumed fish, half ate fewer than 2 ounces a week.

braun.sorenne.2.aug.14But fish contain heart-healthy oils, such as omega-3 fatty acids, says Edward R.B. McCabe, medical director of the March of Dimes Foundation. There’s also limited evidence that fish oils may promote a baby’s brain development. McCabe praised the agencies’ decision to encourage more fish consumption, along with a balanced diet.

So now, instead of telling these women to eat no more than two servings of fish a week, officials advise them to eat at least two servings and up to three servings a week of fish that’s low in mercury. Officials continue to advise women to avoid four fish with higher mercury levels: shark; swordfish; king mackerel and tilefish from the Gulf of Mexico. Those four fish make up less than 2% of fish sold in the USA, Ostroff says.

Nine of the 10 most frequently sold fish in the USA are lower in mercury, Ostroff says. The fish used in fish sticks and other commercial products is also usually low in mercury, he said. Fish that are lower in mercury include shrimp, pollock, salmon, canned light tuna, tilapia, catfish and cod, he said.

“The health benefits far outweigh any risk,” Ostroff says.

The draft’s updated advice did recommend that pregnant or breastfeeding women limit their consumption of white (also called albacore) tuna to 6 ounces a week.
