Seafood Safety Things to know before your trip to the market
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.
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:
Image source Univ. of MN • Image source Stockton College Seafood Safety Methyl mercury
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
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
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
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
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
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…
White Tuna - Albacore • For Women in aforementioned categories • Higher in Hg than light tuna • 6 oz. per week • One normal meal
Chunk Light Tuna • For women in aforementioned categories • Lower in methyl mercury than white tuna • 12 oz. per week
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.
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
HOW added to HACCP Harvest Open Waters to assureSafe Gulf Seafood
Seafood Safeguards: Oil Spill • What do we know about seafood? • Aquaculture? • Imports? • What you may not know. • Marine life (seafood) metabolizes hydrocarbons
