On Wednesday, September 16, and Thursday, September 17, we will be walking the Senate and House office buildings with two things for every member and staff of the Senate Committee on Health, Education, Labor, and Pensions and the House Committee on Energy and Commerce. The first is the t-shirt, rolled inside a small plastic baby bottle, that reads “For Babies’ Sake, Test for Botulism in Infant Formula.” The second is the stack of letters I have sent those two committees since June. Nobody has answered them.
Last week I wrote that the shirts were coming. Both chambers came back to Washington on Monday. The plan has not changed: all 23 HELP offices and all 54 Energy and Commerce offices get two shirts each, carried in by hand, and so do the committees themselves — the HELP Committee at 428 Dirksen and the Energy and Commerce majority and minority staff in Rayburn. That is 77 member offices, each getting a person at the counter rather than a package on a mail cart.
The letters are going in by hand this time
I have written each committee twice. Energy and Commerce received a letter on June 23 supporting H.R. 7867, with the statements and photographs of fourteen families attached, and a follow-up on August 28. HELP received a letter on June 29 and a follow-up on August 28. Four letters, two to each committee. Not one reply.
Mail to a congressional committee goes through screening, then a mailroom, then a cart, and it can sit a long time before it reaches the staffer who works the issue. This week the two letters each committee has not answered go in with the shirts, handed to a person rather than dropped in a bin. A letter in an envelope is easy to file. A letter that arrives with a baby bottle is harder to lose.
What the government confirmed after the first letters
The June letters made an argument. The August letters reported a laboratory result. On August 27 the CDC closed the Nara Organics investigation and found that epidemiologic, traceback and laboratory data showed Nara Organics Whole Milk Organic Infant Formula was contaminated with Clostridium botulinum and made infants sick. Whole genome sequencing linked a patient sample from the Nara outbreak to a patient sample, product samples and an ingredient sample collected during the 2025 ByHeart investigation. CDC reported that both brands were made with milk supplied by Organic West Milk and spray dried by Dairy Farmers of America, and that the matching sequences point to a common source of contamination.
One qualification belongs in every account of this, and I put it in both letters. Neither agency has determined a root cause, and FDA says it does not yet have enough evidence to say whether the milk was contaminated before drying or during it. That question divides responsibility among the companies. It does not change whether the formula was contaminated, or whether it paralyzed babies.
Forty-eight infants in seventeen states in the ByHeart outbreak. Four in the Nara Organics outbreak, in California, Pennsylvania and Washington. Fifty-two babies hospitalized, many on ventilators, each treated with BabyBIG antitoxin that the State of California prices at $69,300 a dose.
What has not changed
Federal regulation, 21 C.F.R. § 106.55, still requires powdered infant formula makers to test finished product for two organisms, Salmonella and Cronobacter. C. botulinum is not on the list. FDA named the organism by genus and species in a March 8, 2023 Call-to-Action letter to the powdered infant formula industry. The rule never followed, and as I wrote yesterday, it still does not require the test.
H.R. 7867, the Infant Formula Safety Modernization Act of 2026, would put C. botulinum on the required testing list, require environmental monitoring inside the plants, hold foreign manufacturers to American standards and require notice to Congress of confirmed positives. Representatives Rosa DeLauro and Jeff Van Drew introduced it on March 9. The Energy and Commerce Health Subcommittee held a hearing on it on April 29. No markup has been scheduled. The Senate passed S. 272 by unanimous consent the same day, which shows this is not a hard vote, but S. 272 reaches only the organisms already on the list.
What we are asking both committees to do
The shirts carry the same requests the August letters did. To Energy and Commerce: mark up H.R. 7867 and report it favorably. To HELP: pass a bill that reaches botulism, whether a companion to H.R. 7867 or one of the Committee’s own. To both: hold an oversight hearing with FDA, Dairy Farmers of America, Organic West Milk, Nara Organics and ByHeart at the table; put the parents at the witness table, because they have already written to you and are willing to say it in person; and send FDA a written question with a deadline asking what its root cause investigation has found, whether it intends to require testing for C. botulinum by regulation, and when.
Quick answers
What is being delivered to Congress on September 16 and 17, 2026? T-shirts packed in baby bottles reading “For Babies’ Sake, Test for Botulism in Infant Formula,” along with hand-delivered copies of four letters Bill Marler sent the Senate HELP Committee and the House Energy and Commerce Committee in June and August 2026, which have gone unanswered. Every member office on both committees receives them, and so do the committee staff offices.
Why is powdered infant formula not tested for botulism? The federal rule at 21 C.F.R. § 106.55 requires finished-product testing only for Salmonella and Cronobacter. Clostridium botulinum is not on the list, even after two outbreaks that hospitalized 52 infants and that whole genome sequencing has linked to a common source.
What would H.R. 7867 change? It would add C. botulinum to the required testing list, require environmental monitoring in formula plants, apply the same standards to foreign manufacturers and require notice to Congress of confirmed positive tests. It has had a subcommittee hearing and is waiting on a markup in the House Energy and Commerce Committee.
Four letters, no reply
My direct line is printed on every one of those letters. By Thursday afternoon every office that can put this bill on a calendar will have it twice, once on paper and once rolled up in a baby bottle. We will see which one gets a call back.
