    Seaweed Labelling Compliance: Unique Challenges in Seaweed Labelling - Zoom Saturday March 16, 2024

    9:30 AM to 4:30 PM ET

    Seaweed is an amazing product, yet it is potentially dangerous to both humans and animals. Many kelps are high in iodine and heavy metals that can cause injury or death.

    Proper labelling can assure consumers are aware of the risks and benefits of your seaweed products, as well as minimize the risk of legal liability for misleading or false labelling claims.

    This online program will include lesson and workshop sessions. Participants will come away with an understanding of labelling issues and strategies to be compliant under USDA, FDA, FTC, and state labelling regulations and laws, including California Proposition 65.

    The course will be taught by Trey Angera. Trey is an experienced attorney with over 30 years of compliance experience with both the USDA and FDA. He has represented and consulted with dozens of food companies throughout the world. He is also the Executive Director of the Maine Seaweed Exchange and General Counsel of Springtide Seaweed, LLC.

    The program cost is $375. Participants can add a private one or two hour(s) consultation on their labels for an additional $100 or $200 respectively. Student scholarships available.

    Why Is Our Seaweed And Company Different?

    Farmed not wild. Solar dried. Tested for safety. Unmatched quality.

    We are unique in the seaweed industry. Here are some of the reasons why:

    • Our seaweed is organically farmed. We do not wild harvest so as to protect native wild beds that are under stress.
    • We use state of the art farming technques that minimize gear and plastics in the ocean, use minimal amounts of fuel, and have the highest yields in the industry. Our farms grow 5 times the average seaweed farms so we need only 20% of the gear other farms utilize.
    • We do not use energy intensive processing methods such as blanching, freezing or mechnized dryers. Our products are dried using solar energy and are custom milled and vacuum packed so that they are shelf stable for years and require no refrigeration or freezers.
    • Our processing maximizes the retention of nutrients and are tested for safety.
    • We are fully integerated from seed to finished product. The entire process is certified USDA organic.
    • We hand harvest in small btches to assure there is no biofouling, invasive species, or poor quality seaweed getting past quality control.
    • We farm year round to maximize yields while minimizing environmental impacts.
    • We integrate other species on our farms, includig sea urchins.

    Our Company

    'Springtide' in old English means 'springtime'. This is harvest season for the seaweed crop. A spring tide is also the time when the tide "springs forth" during the new and full moon, giving us the highest and lowest tides of the month.

    Springtide Seaweed operates the largest organic seaweed farm in North America in Downeast Maine, cultivating some of the finest seaweeds in the world for people and the planet. We also operate a state of the art USDA Organic seaweed nursery and processing facility in Gouldsboro, Maine.
