The horseshoe crab was plentiful when I was a child at Priscilla Beach in the fifties. There are still some when my children were young, late sixties, early seventies. I don’t remember when I last saw one.—Mary Mullaney
Horseshoe Crab Protection Bill Advances to House Ways & Means!
We are pleased to share that H.898, An Act to End the Use of Horseshoe Crabs for Bait, has been reported out favorably by the Joint Committee on Environment and Natural Resources.
We are deeply grateful to the eight members of the Committee who voted in favor. Their support reflects a growing recognition that protecting horseshoe crabs is essential to restoring coastal ecosystems, supporting migratory shorebirds, and advancing Massachusetts’ biodiversity goals. Please thank them!

We also appreciate the three House members who reserved their rights. We welcome the opportunity to provide any additional information that may be helpful as the bill continues to move forward.
The bill has now been assigned a new number: H.5266, and has been referred to the House Committee on Ways and Means, where its next phase of review will take place.
This stage is critical. The Committee will consider the bill’s broader policy and fiscal implications as it determines whether the legislation should advance.
Next Steps: Thoughtful Outreach Matters
If you would like to help, respectful, informed outreach can make a meaningful difference.
We encourage supporters to:
- Contact members of the House Committee on Ways and Means
- Express support for H.5266
Emphasize that:
- The bill advances biodiversity protection and coastal resilience
- It aligns Massachusetts with regional leadership (New York and Connecticut)
- It does so without cost to the Commonwealth
- It is supported by scientists, conservation organizations, and hundreds of residents
If you have a personal or professional connection to a member of the House Committee on Ways and Means, your voice is especially important.

Strong Support for H.5266 (formerly H.898)
The excerpts below represent just a small sample of the many letters submitted in support of H.5266. Far from being driven by emotion or lack of understanding, this effort is grounded in the work of scientists, conservation professionals, and others with deep expertise in coastal ecosystems.
The International Conservation Fund
The International Conservation Fund, based in Boston, is focused on protecting biodiversity and endangered species where they are most imperilled.
"There should also be no increase in the allowed take of these crabs for the biomedical industry. With widely available, more effective synthetic alternatives accepted by the by the US and European Pharmaceopeias, there is no longer any reason to bleed horseshoe crabs to make assays to test for endotoxin contamination in injected drugs and vaccines."

Center for Biological Diversity
"Phase out the biomedical bleeding harvest. Rather than increase the biomedical bleeding harvest, DMF should gradually decrease the harvest toward an eventual phase out. Experience shows this is feasible and practicable—harvesting horseshoe crabs for biomedical bleeding purposes is currently prohibited in Connecticut and phasing out in New York. See Conn. House Bill No. 6484, Public Act No. 26-3 (effective Oct. 1, 2023); N.Y. C.L.S. Envtl. Conserv. L. § 13-0331.
Both states have banned the harvest for biomedical bleeding because horseshoe crab blood is no longer necessary for endotoxin testing. Standards-setting body U.S. Pharmacopeia set industry standards for synthetic endotoxin test methods, Congress recently directed the U.S. Food and Drug Administration to update its guidance to accept synthetic endotoxin testing in the manufacturing of new and existing products, and large biomedical companies like Eli Lilly are making the transition to synthetic.
If Connecticut and New York find it feasible and practicable to phase out the horseshoe crab biomedical bleeding harvest, so should Massachusetts."

"There is no need to permit—let alone increase—the harvest of horseshoe crabs for biomedical use as non-animal derived alternatives can replace reliance on LAL from horseshoe crab blood."

American Bird Conservancy
"There are bait alternatives to horseshoe crabs and synthetically-derived medical safety tests that do not require the harvest and bleeding of horseshoe crabs. Synthetically-derived medical safety test alternatives are proven safe and effective and have been successfully adopted by companies, such as Eli Lilly. Continuing to harvest horseshoe crabs, when its not necessary, places undue ecological pressure on Atlantic Coast ecosystems."

Horseshoe Crab Recovery Coalition
The Horseshoe Crab Recovery Coalition is a collaborative advocacy group working to protect and restore horseshoe crab populations along the U.S. East Coast.
"Massachusetts is home to some of the same companies whose research has proven that we no longer need horseshoe crab blood to ensure patient safety. In effect, the bleeding companies are marketing the animal-derived agent side-by-side with the newer animal-free alternatives. Synthetic endotoxin tests are recognized by the US Pharmacopeia as equivalent and are currently used in at least 10 FDA approved medicines including treatments for diabetes, obesity, COVID-19 and other sterile medicines and vaccines. Given the strong biopharmaceutical presence in Massachusetts, the state should be working to accelerate the transition – not give the bleeding industry the freedom to operate with relaxed limits."

We are grateful to the legislative petitioners who supported H.898 for their leadership and commitment.
A brief note of thanks from constituents can go a long way—we encourage you to let them know their support matters.

Massachusetts Horseshoe Crab Advocates Have a Plan!
The Mission of the Massachusetts Horseshoe Crab Collaborative is to restore horseshoe crabs in Massachusetts to numbers closer to their historical levels allowing them to fulfill their ecological role in the marine ecosystem and support a statistically significant increase in the shorebirds and in the many marine species dependent upon them, and thereby, renew the Web of Life at the edge of the sea. Review the plan. Join the Collaborative!
View the Horseshoe Crab Collaborative Strategic Plan here.
Contact the Coordinator Sharl Heller at slheller@comcast.net for more information and to join the Collaborative.

Who We Are
SEMPBA volunteers want to better understand horseshoe crabs; their critical role in human health and in the global ecosystem—particularly in their evolutionary ability to sustain migrating shorebirds on long intercontinental migrations. That is why SEMPBA volunteers participate in the Massachusetts Department of Marine Fisheries Spawning Horseshoe Crab Survey program, providing data to the Commonwealth help set limits on their "take" and why we created a Facebook page to help focus advocacy efforts where they may do the most to ensure that these ancient creatures rebound and flourish as they have for millennia.
Keep current and find more information on the SEMPBA Horseshoe Crab Advocates Facebook Page.
We invite you to join in this effort with us. visit our website: www.horseshoecrabs.org.
