  22. Why Seafood? Seafood isa wonderful food!

  23. Seafood in a wonderful foodThere are just so many choices!!! • Omega – 3 fatty acids • EPA • DHA • Moderate evidence shows benefits @ ~8 oz per week • Fats in seafood are considered oils • Image source Penn State

  24. Seafood Safety Things to know before your trip to the market

  25. Seafood-Borne Illness Cases

  26. Seafood Safeguards: Oysters • About 20 million people eat raw oysters annually. • However for some people eating raw oysters can cause serious injury or death. • The cause is a naturally occurring marine bacterium Vibrio vulnificus.

  27. Liver disease Chronic Kidney Disease Diabetes Mellitus Stomach problems Cancer Immune disorders Long-term steroid use Older adults Seafood Safeguards:Oyster Risk Factors • Certain health conditions can put you at risk • from Vibrio infection. These conditions include:

  28. Image source Univ. of MN • Image source Stockton College Seafood Safety Methyl mercury

  29. Seafood Safety:Methyl Mercury • Mercury occurs naturally in the environment and can be released through industrial pollution (coal fired power plants) • Bacteria in the water convert mercury into methyl mercury • Bacteria are ingested by small aquatic organisms

  30. Seafood Safety:Methyl Mercury • Fish ingest methyl mercury when they feed on these aquatic organisms • People can ingest methyl mercury when they eat certain long-lived species of fish • The longer the fish live the more they have eaten and stored within their bodies

  31. Seafood Safeguards:Methyl Mercury • Nearly all fish contain trace amounts of methyl mercury, which are not harmful to humans • Evidence shows that health benefits from consuming seafood outweigh the health risks associated with methyl mercury

  32. Seafood Safeguards: Methyl Mercury& Women Who are Pregnant or Breastfeeding • Seafood is an important part of a balanced diet, especially for pregnant and breastfeeding women (Omega-3s, DHA, etc.) • Recommended that these women consume at least 8 oz and up to 12oz of a variety of seafood per week (typical serving size is 3-6 oz). • Concern arises over the fact that high levels of methyl mercury may harm a baby’s developing nervous system

  33. Seafood Safeguards: Methyl Mercury& Women Who are Pregnant or Breastfeeding • Select a variety of other kinds of fish- including: • Shellfish (shrimp, crabs, oysters, clams etc.) • canned fish • smaller ocean fish • farm-raised fish • Value seafood

  34. Seafood Safeguards: Methyl Mercury& Women Who are Pregnant or Breastfeeding • These women should avoid long-lived species such as: Sharks, Swordfish, King Mackerel (Kingfish), and Tilefish. • FDA also recommends (as a matter of public heath advise) that young children not eat these fishes. • It’s really easy to do…

  35. A Special Note on Tuna

  36. White Tuna - Albacore • For Women in aforementioned categories • Higher in Hg than light tuna • 6 oz. per week • One normal meal

  37. Chunk Light Tuna • For women in aforementioned categories • Lower in methyl mercury than white tuna • 12 oz. per week

  38. Seafood Safeguards: Methyl Mercury& Women Who are Pregnant or Breastfeeding • Remember: There is no harm in eating more than 12 oz. (or 6 oz. of albacore tuna) in one week, just don’t do it on a regular basis. • If you eat more fish during one week cut back the next week or two to be just fine.

  39. Seafood SafeguardsCiguatera • The most commonly reported marine toxin disease in the world is Ciguatera, associated with consumption of contaminated reef fish such as barracuda, grouper, and snapper. • Caribbean & tropics • Reef fish • “Big” fish
