Foods that contain vitamin B-1 are destroyed by sulfites, which also raise health concerns for some people who are sensitive to the preservative. According to the Center for Science in the Public Interest, at least 12 people died as a result of sulfites in the 1980s, and scientists believe that many more people died as a result of sulfite sensitivities in earlier decades. Manufacturers are required by the Food and Drug Administration to list sulfites on product labels. According to research that was published in the “Journal of Food Protection” in 2004 and cited by scientists at the Center for Food Safety and Applied Nutrition, the FDA forbids the use of sulfites on fresh fruits and vegetables but permits their use in other foods as long as it is disclosed on the product label. While other nations have restrictions that range between 60 and 100 ppm for raw shrimp and as low as 30 ppm for cooked shrimp, the FDA limits the quantity of sulfite residue on all shrimp to 100 ppm.
Sulfites: what are they?
Sulfites are a type of preservative frequently found in food and medicine. Sulfites, metabisulfites, sulfuric acid, and bisulfites are some of them. They are used in food to condition dough (bakeries), bleach food, and inhibit bacterial development (wine), browning, and oxidation of food (shrimp, sliced potatoes) (cherries). Additionally, they help prevent browning and oxidation in several medicines. Epinephrine, isoetharine, isoproterenol, hydrocortisone, dexamethasone, and prednisolone are some asthma medications that may include sulfites. Sulfates should be distinguished from sulfites (albuterol sulfate). Sulfates are safe, however sulfites may be toxic to some people.
shrimp allergy and sulfite
Does anyone know if the frozen shrimp from Costco contains sulfites? My understanding is that it must be disclosed on the label, but my allergic BIL believes that if the shrimp are treated at the moment of capture, it need not be disclosed.
I am tolerant of this. When shrimp are captured, they may be treated with sulfite or another preservative to prevent the growth of certain sort of black mold. I usually do OK if I first soak them in a gallon of water and two tablespoons of hydrogen peroxide. Just so you know, I can just rinse other fish well. Bottled lemon/lime juice, dried fruit, coconut beverages, and dough conditioners are my other four main sources of sulfites.
To ensure product quality, sodium bisulfite is added during shrimp post-harvest operations. Food safety is not a major worry for shrimp handlers because shrimp are often toxin-free, are rarely consumed uncooked, and heating destroys dangerous germs. Sodium bisulfite prevents shrimp from developing melanosis, often known as “black spot,” which is a darkening of pigments in the membranes and meat beneath the shell that gives the product an unappealing appearance. To keep their shrimp looking healthy, shrimp growers dip baskets of collected shrimp into a sodium bisulfite solution.
I went to Whole Foods and saw that their shrimp is particularly advertised as being sulfite-free, so I decided to serve that instead of the shrimp I had originally purchased from Costco. Since we refer to Whole Foods as “Whole Paycheck” around here, I was merely interested for the future. I’m going to ask Costco by email. Their shrimp is probably not safe, in my opinion.
As someone who has a shellfish allergy, I always assume that I should avoid something, treat myself with something comparable to Benedryl, or both.

What You Need to Know About Shrimp and Chemicals
Cheaper shrimp, whether farmed or wild-caught, are more likely to have undergone chemical treatment, particularly sodium tripolyphosphate and sodium bisulfite.
Shrimp heads and shells go through a process known as melanosis, or “black spot,” which darkens them after being harvested and exposed to oxygen. Sodium bisulfite is used to prevent this from happening. Consider this innocuous reaction as the marine equivalent of how apple flesh browns after being chopped.
The chemical is a component of the slushy brine mixture that most fishing boats use to store shrimp before bringing them ashore for additional processing. When the processing plant is remote from the farm, it may also be applied to shrimp raised in farms.
However, adding sodium bisulfite is simply decorative and does not actually prevent the shrimp from degrading. American consumers prefer their shrimp to be completely pink and shadow-free.
However, a small amount of melanosis is not always detrimental. Melanosis does not harm flavor, according to Wegmans’ seafood manager Steve Philips, and it may even indicate that the shrimp are chemical-free (which is one of the criteria for all the shrimp sold at the supermarket chain).
According to Mr. Philips, “the presence of melanosis is the absence of chemicals, and the absence of melanosis is not the presence of freshness.”
The industry’s method of putting a finger on the scale is tripolyphosphate. The chemical, which is frequently used with scallops as well, makes seafood absorb water, causing it to gain between 7 and 10 percent of its original weight.
Tripolyphosphate-treated shrimp cooks differently than shrimp that has not been treated. When you try to sauté them, they steam rather than sear because of their high moisture content. Additionally, they have an unusual translucent appearance even after cooking and a bouncey, rubbery texture.
The addition of tripolyphosphate to seafood is like putting water to ham, according to Jim Gossen, president of the Gulf Seafood Foundation.
You can purchase flavorless deli ham that contains 40% water, he claimed. Or you could purchase prosciutto.
By the Food and Drug Administration, sodium bisulfite and tripolyphosphate are both regarded as safe in small dosages. The general American population, however, only accounts for 1% of those who are sensitive to sulfites.
Try to purchase shrimp with the shell on and peel it yourself to prevent tripolyphosphate, which is typically added to shrimp after it has been peeled. (Save the shells for a stock of shrimp.) However, sodium bisulfite is an exception to this rule.
You could also read the packaging’s small print: Labels that you can find on bags of shrimp taken straight out of the freezer case must indicate all chemicals.
The only way to know for sure if the mounds of shrimp on ice you find at grocery stores and fishmongers are chemical-free is to ask — and hope the person behind the counter knows the answer.

Why are there sulfites in shrimp?
In accordance with European law (EC Regulation No. 1333/2008), food additives are now defined. Because they inhibit bacterial development on meals and stop lobster and shrimp from oxidizing or browning, sulphur dioxide (E220) and sulphite (E221-E228) are commonly employed in food processing as preservatives. Sulfiting agents have been used for a long time by farmers, fishermen, and shellfish processors in a variety of warm- and cold-water crustacean species as a treatment to ward off melanosis (blackspot), a natural process that causes the shell to turn black after harvesting due to Polyphenoloxidase enzyme systems that remain active during refrigeration or ice storage. The most well-established adverse reaction in humans to this food ingredient is sulfite-induced hypersensitivity. In the current study, the Monier-Williams procedure was used to assess the presence of sulfites in various frozen and thawed species of shrimp and prawn belonging to the Penaeoidea superfamily in order to conduct a risk assessment and determine the levels of consumer exposure to this class of additives from these fish products. The appropriate consumer information on labels was also examined in addition to analyzing and monitoring the correct use of the additive in accordance with the restrictions imposed by the European rules. Both the entire shrimp (shell on) and the inedible sections of the shrimp were analyzed (head and peeled shell). For head-on-shell-on shrimp, the sulphites concentration in frozen samples (reported as SO2 mg/kg mean value +-S.D.) was 214 + 17.43; for shell-on headless shrimp, 170.73 + 14.99; and for peeled and deveined shrimp, 112.90 + 27.55. The sulphites concentration (reported as SO2 mg/kg mean value+-S.D.) for these samples, all head on shell on, was 160.05+-26.15 and 292.54+-146.04, respectively. Thawed shrimp were acquired from mass merchants, channel, local fish markets, and seafood shops and purveyors. All samples revealed significantly increased concentrations of non-edible components.
Do sulfites exist in frozen shrimp?
Ranges of sulphite concentrations for all frozen prawn samples. Between 10.7 and 380.7 mg/kg of sulphite was found in the edible sections of frozen shrimp (mean value: 105.3 mg/kg; standard deviation: 120.6 mg/kg).
Are shrimp sulfates?
Fresh and frozen shellfish like shrimp and crab, wine, lettuce and other packed salad greens, dried fruit, maraschino cherries, pickles, sauerkraut, and lemon, lime, or grape juice are common foods that may have been exposed to sulfites. Look for compounds like sodium sulfite and sodium bisulfite on packaging. If you have an allergic reaction after consuming a food item containing these substances, tell your doctor.
Are there sulfites in eggs?
Chemical substances that include the sulfite ion are known as sulfites, sometimes known as sulfur dioxide. Naturally occurring sources of them include black tea, peanuts, eggs, and fermented foods.
Do shrimp include preservatives?
Pentasodium triphosphate, commonly known as sodium tripolyphosphate or STPP, is a chemical that is used in food, paint, detergents, soaps, cleaning supplies, and ceramics. In order to “help retain…tenderness and moisture throughout storage and transit,” Wise Geek reports that it is frequently used as a preservative in seafood like shrimp and scallops. Seafood’s physical appearance can be enhanced using STPP, which can also hold onto water to make the product heavier and more expensive.
Does salmon have sulfites in it?
Several foods, including maple syrup, pectin, salmon, dried cod, corn starch, lettuce, tomatoes, soy products, eggs, onions, garlic, chives, leeks, and asparagus naturally contain sulfites.
What additives are included in shrimp?
A preservative known as sodium tripolyphosphate may be present in both fresh and frozen shrimp (STP). The flavor and texture of the shrimp may be impacted. If it does, this preservative will often be labeled on the back of the container for frozen shrimp.
What foods contain a lot of sulfites?
Potatoes that are dry, gravies, sauces, fruit toppings, maraschino cherries, pickled onions, maple syrup, jams, jellies, biscuits, bread, pies, and pizza dough. Occasionally, sachets of the sulfite-containing preservative will be sent with dried apricots and grapes. Normally, dried sultanas don’t include sulfites.
Does eating shrimp cause inflammation?
Additionally, shrimp has a number of minerals, including omega-3 fatty acids, that may potentially improve health (3).
Shrimp is an exception, according to studies, as most meals high in cholesterol are also high in saturated fats (6).
Shrimp has a number of advantageous qualities that may exceed its cholesterol content, even if more research is required to understand its impact in heart health.
Although shrimp has a lot of cholesterol, it also has omega-3 fatty acids, which have been found to help heart health. Additionally, studies on shrimp have revealed advantages for health.
