Shrimp and Preservatives: Part 1

Below is the question I asked of a friend's husband who works in Oregon fisheries. I'm continuing my research for the bigger shrimp we buy here in Florida.

This addresses ONLY small salad shrimp caught by this company off the West Coast

Hey Wiz....

Not sure if DH can answer this question, but he's a seafood expert and I'm hoping shrimp falls into that same category.

I've been told here in Florida that ALL shrimp gets coated with a preservative, even the "never-frozen, fresh-caught local" shrimp netted in our Inter-coastal waters. I was also told the ONLY way you can eat a shrimp without preservatives is to catch it yourself.

I tried doing the research online and the diversity of shrimp preservatives is almost scary:

Sodium Tripolyphosphate

Sodium bisulfate

Sodium metabisulfate

Sodium Benzoate

Ascorbic Acid

Low Molecular Chritosan 1

Phytic acid

Crustacean preservative (which could be any of the above, I guess)

My question to the DH is this: Do most seafood preservatives come off when you remove the shell or skin? Or does the preservative leech into the flesh, so you're eating the preservative no matter how much you clean it?

Thanks.

Marilyn

Our shrimp fishery is very different from what you describe. The shrimpers here, make 4 day trips, and store the whole shrimp in their holds layered in ice. These are small “salad” shimp: pandalus jordani is the species. The average finished count per pound ranges from 250 to 400; nothing like the gulfs 10 to 30 count per pound for tails. The boats add no chemicals at all. HACCP regulations require them to certify this fact.

The plant cooks and peels this shrimp mechanically and does use a sodium tripolophosphate bath, which is drained, prior to cooking and peeling; we then add salt before packaging. Our product is a ready to eat product. The tripolyphosphate on the finished shirmp is not detectable and so FDA does not require listing it as an ingredient. We must list salt which is added for flavor.

The peeling process uses huge volumes of water. Each machine uses about 5000 gallons of fresh water per hour. Sanitation is a major concern. Lysteria is our biggest fear.

Many of the chemicals you list are familiar to me; many have been tried over the years. On the West Coast chemical additives are no longer used on any fish we process (not the case 20 years ago). All this changed with the labeling laws.

Hope this helps. JERRY

 
Thank you for your timely post

Last night I made a shrimp pasta dish and for the second time in a row the shrimp had a most unpleasant, chemical taste to it. We had been purchasing it from the seafood counter at our local supermarket (which we knew wasn't 'fresh' but it was basically our only choice from the counter). I won't purchase it again. instead I'll try the frozen, raw packaged shrimp in the frozen section of the market (I am hoping that it isn't the same shrimp the counter uses. I guess I could ask...although I'm kinda afraid of the answer)

 
Very interesting, Marilyn

It makes me wonder about all the shrimp imported from Mexico, Thailand, etc. though. Do other countries have to follow what the US regulations demand if they package the shrimp and export it to us frozen?

Thank you for following up and asking someone in the industry- it was an enlightening read.

 
I WON'T touch the stuff from Asia these days after hearing horror stories

from a friend in the food & hospitality industry that travels over there. Particularly China but I'm avoiding it all now. I want as much US/Canada seafood as possible and so far no reports on bad stuff from South America.

 
20 years ago, I know Mexico and South America did NOT have to follow any of the rules

and restrictions set down by our government--at least with regard to apples.

I was at a food convention in Chicago in 1987 and was asking a representative from the Washington State apple group why all Granny Smiths seem to have tiny brown pin-point spots inside them.

He explained that most Granny Smiths came from Mexico and South American and that they could ship them whenever they wanted. American growers are mandated to leave the apples ON THE TREE for a certain number of days before they are allowed to pick them. Shorter growing/picking periods meant foreign growers could flood the market with cheaper produce while American growers had to leave their produce on the trees. American growers are also restricted in what they can spray on trees, while the imported foods had no restrictions.

For the current situation: I have no clue how valid any of this information is since it's so old, but I KNOW that trip made a difference for me in buying apples. From that point on, I started buying local or from health food stores. And try to buy while in season.

I have given in to Braeburns from Australia when they are fresh---since they come in months before our apples are ready. What can I say? I'm weak. Call me Eve.
