Discussion 

• December 5, 2023 notes were accepted as written. 

• 2026 Sunset: DL-Methionine (MET) (NPP). The lead introduced the methionine review by noting that

each time it is reviewed, it garners attention from the community, and each time has resulted in 

relisting. Methionine is a natural component of bird diets, mainly from insects. In birds being fed a 

vegetarian diet, it is often not adequate, so it is supplemented. The lead relayed feedback from 

stakeholders that the updated annotation, which limits MET to 2 lbs. over the lifetime of the bird, is 

workable and hasn’t been a hinderance. The LS talked about several topics and ideas with regard to 

MET: A scenario in which there is a supply change disruption and feed is in short supply; A future 

proposal to remove the restriction based on the notion that even pastured birds may not getting 

enough methionine in their diet and need higher supplementation; A research priority on alternatives; 

The newly published Organic Livestock and Poultry Standards; and US standards European standards vs. 

(in which MET is not allowed). 

• 2026 Sunset: Peracetic acid/Peroxyacetic (NL). The lead summarized the substance review. Peracetic 

acid is compound of hydrogen peroxide and acetic acid, and its breakdown products are benign. It’s an 

alternative to chlorine, a highly effective sanitizer, not persistent in environment, and an important tool 

so producers have several options in rotation. The lead will finalize the draft and submit it to the NOP 

for the Spring meeting.

• 2026 Sunset: Oxalic acid dihydrate (KH). The lead summarized oxalic acid, which is used as a parasiticide 

for varroa mites in honeybee hives. It was added to the list recently, and it appears that the alternative 

(sucrose octanoate esters (SOE)) are still on the list. SOE was recommended for removal in 2018 but the 

NOP did not implement the recommendation. The lead will finalize the draft and the LS will submit for 

the Spring meeting. 

• Additional Items. None.

• The meeting was adjourned

o Vitamin TR. The LS Chair and the NOP have been discussing the questions for the TR on vitamins. 

The TR contractor is seeking some clarification about the questions posed by the LS previously. 

The NOP will send feedback and an additional request by the Subcommittee. 

o A member suggested an idea for a work agenda project on feed additives that will help reduce 

methane, which could tie into the climate-smart initiative. This may be a candidate for a 

research priority rather than a work agenda item. Members shared thoughts and ideas, and 

discussed research about emissions from different livestock practices. A member added that 

there currently is a lot of research and data being generated about other greenhouse gasses, 

and will locate one study in particular and share it with the Subcommittee.

Discussion

• November 7, 2023 notes were deferred to next call as they are not currently available 

• 2025 sunsets are due tomorrow. Please send reviews to the LS Chair and he will compile them and send 

them to the NOP. 

• 2026 sunsets. Due to the LS by December 5 so all members have time to read and prepare for 

discussion. 

• 2026 Sunset: Moxidectin (KH). The lead briefly summarized the history of the substance on the National 

List, and parasiticides in general. She is still reviewing the information and hasn’t yet composed any 

questions. Members discussed various aspects of “emergency use” of parasiticides, and specifically the

fenbendazole annotation change. The annotation changed the withdrawal period from 90 days to 2 days 

in cattle. There was a lot of support for relisting moxidectin during the last review, but the lead would 

like to add more information to both parasiticide reviews regarding use and need from the veterinary 

community. The LS will revisit this at a future call. 

• 2026 Sunset: Magnesium sulfate (BC). The lead summarized the substance, and noted that in the past 

there was strong support for relisting. There were no additional questions from members. The LS 

completed the review and will submit it to the NOP. 

• 2026 Sunset: Trace minerals (BC). The lead summarized the substance and emphasized that mineral 

deficiencies produce negative effects in animals. He also noted the issue of mineral deficiencies in soils. 

The TR is incredibly detailed and in-depth. A member added that most of these products are 

predominately sodium chloride, which is considered an ancillary substance, although trace minerals are 

given in micro-doses. and it is not viewed as a concern. The LS completed the review and will submit to 

the NOP. 

• Additional Items. 

Swine. The group discussed the issue of organic swine, which was added to the research 

priorities in Fall 2023. Members discussed the possibility of adding a work agenda project, and 

explored various aspects, such as market development, need for regulation updates, and 

consumer demand. The NOSB Chair noted that the CACS talked about working on a market 

development project, and this might fit well in that context. There were several lingering 

questions, and the LS may choose to update the Research Priority language.

• The meeting was adjourned

• Adjourn

Discussion

• Travel questions/concerns. The group discussed travel logistics for the NOSB meeting in Providence. 

• Fall meeting logistics, overview of run-of-show. The group briefly reviewed the meeting agenda and 

noted that since the public comment period just closed, they have only had time to skim the comments. 

• Public comments. The lead reviewer for vaccines indicated that there didn’t seem to be much 

controversy and commenters were supportive of the Board’s direction. He also remarked that while no 

one loves it, they recognize that it’s necessary for animal welfare. A member mentioned that there is a 

contingent of stakeholders that continues to push for commercial availability for vaccines. A member 

asked whether mRNA vaccines would be considered GMO, and BC confirmed that they are GMO. The LS 

may mention this at the NOSB meeting for informational purposes. 

• Additional Items. 

o The group discussed swine and the Chair reminded members that it was added to the research 

priorities and is not a work agenda item for the Livestock Subcommittee. 

• The meeting was adjourned

Agenda

• Review June 20, 2023 notes

• Research Priorities (BC/All) 

• Additional Items

• Adjourn

Discussion

• June 20, 2023 notes were approved as written. 

• Research Priorities (BC/All). The lead introduced the document noting that there were 3 different 

entries that all focused in parasiticides, so he combined them into one entry. There were no objections 

by other members. The LS has 5 research priorities including one on alternatives to DL - Methionine. A 

member noted that AAFCO (Association of American Feed Control Officers) is critical to the conversation 

on DL-Methionine, as they regulate the safety of feed of livestock. He will add some language to the 

document regarding this. He also noted that there is scant information about insects and safety in feed, 

which is a barrier. 

Members discussed ideas for two future research priorities: one addressing dairy and climate change, 

and one on organic pork. Members felt that both topics would benefit from input from economists on 

market/supply management. NPP will write the research priority on dairy for the Spring 2024 discussion 

document, so they aren’t introducing a new topic to the Fall 2023 document. 

On the topic of pork, the lead reached out to farmers (both small scale and larger scale) to ask about 

barriers to organic pork production, and both profit margins were a problem. There are also other 

limitations such as lack of slaughter-houses and a small market. The LS will add a research priority to get 

the discussion started on how to “characterize market and production barriers to the expansion of 

organic pork production”. 

The LS will complete the research priorities document via email and submit it to the Materials 

Subcommittee before the August 8 Materials call, on which they will vote. 

• Additional Items. None.

• The meeting was adjourned

Discussion

• June 6, 2023 notes were accepted as written. 

• 2025 Sunset: Glycerin(e) (KH). The lead summarized the use, manufacture, and alternatives of glycerine, 

noting that it was straight forward, and commenters were supportive of relisting. Commenters did 

mention wanting more information on the hydrolysis process.

•

2025 Sunset: Lime, hydrated (KH). The lead summarized the public comment and Board discussion from 

the Spring 2023 NOSB meeting, and the LS moved to a vote. Most commenters were supportive of 

relisting. Although the use is very explicit, commenters mentioned other uses. 

Motion to remove lime, hydrated from the National List 

Motion by: KH

Seconded by: BC

Yes: 0 No: 4 Abstain: 0 Recuse: 0 Absent: 2

• 2025 Sunset: Electrolytes (BC). The lead summarized comments from the Spring 2023 meeting. 

Commenters suggested specifying allowed uses, which are already specified in the listing. 

Motion to remove electrolytes from the National List 

Motion by: BC

Seconded by: KH

Yes: 0 No: 4 Abstain: 0 Recuse: 0 Absent: 2

• 2025 Sunset: Biologics - Vaccines (BC). The lead noted that this is complex, and it appears twice in OFPA 

– once noting that vaccines are universally allowed, and once noting they are allowed as long as they go 

through the sunset process. In 2019 the NOSB passed a recommendation with a suggestion about how 
to solve this, but NOP has not implemented that recommendation. The LS encourages the NOP to 

implement the 2019 recommendation, and has included language in the review stating that. The group 

discussed the listing, in which all vaccines are encompassed as a group, and noted that certifiers review 

them as a group. One commenter disagreed with the 2019 recommendation indicating that it could 

place an undue burden on farmers and veterinarians. The LS may ask the NOP for a response and update 

about this at the public meeting in the Fall. 

Motion to remove biologics - vaccines from the National List 

Motion by: BC 

Seconded by: ADB

Yes: 0 No: 4 Abstain: 0 Recuse: 0 Absent: 2

Discussion

• May 16, 2023 notes were accepted as written. 

• 2025 Sunset: Alcohols: Ethanol, Isopropanol (NPP). The lead indicated there was no public comment 

and not much new to add from the Spring meeting. The LS moved to a vote on the two listings.

• 2025 Sunset: Aspirin (KH). The lead summarized the use of aspirin in Livestock, which is used to treat 

inflammation, fevers, and as a pain reliever. Consistent with other substances used for pain relief, 

stakeholders are supportive of relisting. The LS moved to a vote. 

Motion to remove aspirin from the National List 

Motion by: KH

Seconded by: BC

Yes: 0 No: 5 Abstain: 0 Recuse: 0 Absent: 1

• 2025 Sunset: mineral oil (BC). Mineral oil is used as an external parasiticide and as a lubricant, and the 

lead indicated its importance for livestock health. Commenters were strongly in favor of continued 

listing. A member asked about quantities used and if it is an issue. The lead included that info in the 

review. Another member mentioned use patterns and that it is helpful to include that information in the 

review. The lead will send the final draft to the Chair and the NOP by June 20. The LS proceeded to a 

vote.

Seconded by: KH

Yes: 0 No: 5 Abstain: 0 Recuse: 0 Absent: 1 

• 2025 Sunset: phosphoric acid (ADB). The lead summarized the use of phosphoric acid as a cleaner to 

remove deposits in dairy operations. There are no alternatives. Stakeholders noted that it does not need 

to be rinsed, but the regulations allow for that. The lead is waiting for additional information from the 

Accredited Certifiers Association (ACA) and would like to clarify that at the upcoming meeting. The 

group discussed concentration and a member pointed out that there will be use instructions, and the 

FDA would approve levels when reviewing products. The lead will look at labels for more information. 

The LS moved to a vote.

• Additional Items. The LS discussed the list of TR requests, and how TRs can provide information to

Certifiers when reviewing brand-name products for GMOs. Nate Lewis will work with the Materials

Subcommittee on the Excluded Methods list, and is looking to integrate the work on excluded methods 

into future TR requests. 

• The meeting was adjourned

Agenda

• Review April 4, 2023 notes

• Debrief Spring 2023 Meeting

• Review May - October Timeline

• 2026 Sunset TR Determinations

o Xylazine (ABD)

• Determine if May 30th call is necessary

• Work Agenda Items (if time)

• Research Priorities (if time)

• Additional Items

• Adjourn

Discussion

• April 4, 2023 notes were accepted as written.

• Debrief Spring 2023 Meeting. Members shared their perspectives about the Spring meeting, which 

were all positive. 

• Review May - October Timeline. The group reviewed the upcoming schedule. See tables below for 

discussion dates for 2025 sunsets. The 2026 draft sunsets will be due to the LS Chair December 1.

• 2026 Sunset TR Determinations

o Xylazine (ABD). The lead indicated that the LS will likely approach FDA to glean some additional 

information about use, and not request a new TR. 

o The LS will request a total of 3 limited scope TRs for 2026 sunsets. 

o Vitamins (BC). A member relayed information from the Handling Subcommittee call regarding 

fermentation, as it relates to vitamins. The conversation revolved around the need to address 

GMOs in NL items, rather than addressing individual substances or listings. Members suggested 

asking a question in the Limited Scope TR although acknowledging that it might be difficult to 

gather information as the listing for vitamins is so big. The lead will narrow the focus of the 

questions. A member asked if vitamin manufacturers are required to disclose manufacturing 

processes. The LS Chair and lead reviewer for vitamins will re-review the previous TR and 

determine how to proceed. 

• May 30th call. The LS will not schedule an additional call.

• Work Agenda Items (if time). The group discussed a potential work agenda item on swine, which was a 

suggestion from stakeholders at the last meeting. A member noted that California just passed swine 

regulations (Prop 12). Another member noted the most recent NASS data for swine: there are about 100 

farms with swine, and about 20,000 animals total, and so perhaps there is a growth opportunity. 

Members discussed the barriers to raising organic swine, which include treatments for worms, required 

amino acids and lysine, and lack of slaughter facilities. The LS discussed writing a discussion document to 

allow the community to provide feedback. A member suggested reviewing the listing for casings as well. 

The LS will talk more on next call. 
• Other potential work agenda items for discussion. The group briefly discussed goats and dry matter 

intake (DMI), noting that there isn’t much information in the pasture rule about goat/sheep feed levels. 

Members also suggested turkeys may be a candidate for a future work agenda item.

• Research Priorities (if time). Deferred to June 20 call. 

• Additional Items. None.

• The meeting was adjourned

Discussion 

• March 7, 2023 notes were accepted with minor changes. 

• New member introductions. Members introduced themselves and welcomed two new NOSB members. 

• Determine 2026 sunset TR needs. The group reviewed the list of 2026 sunsets and determined the need 

for TRs. The HS will request 3 limited scope TRs for the following: Hydrogen peroxide focused on 

Livestock uses; Vitamins, specifically to seek info about potential GMOs used in the production; and 

Iodine, with questions focused on nonylphenol ethoxylates (NPEs). ADB will revisit the previous 

tolazoline review so they can sync its review with xylazine since they work in tandem. The HS will then 

determine if a new TR is necessary. 

• Additional Items. None. 

• The meeting was adjourned

Agenda

• Review February 7, 2023 notes

• 2023 Spring Meeting (Agenda, etc.) 

• 2026 Sunset Process and Timeline

• Additional Items 

• Adjourn

Discussion

• February 7, 2023 notes were accepted as written. 

• 2023 Spring Meeting (Agenda, etc.). The Chair shared the work timeline for the next several months

including the 2025 sunsets. The LS scheduled dates for document submission, assigned review buddies, 

and scheduled dates for final discussions and votes. Similar to the process in Crops and Handling, 

members will submit all documents by May 19, 2023, and schedule discussion/vote dates (see table 

below), and submit final reviews for the Fall 2023 meeting no later than two weeks after the vote. 

• The May 2 call was cancelled as it falls immediately after the conclusion of the Spring meeting. 

• 2026 Sunset Process and Timeline. The group discussed the 2026 sunset substances to determine the 

need for TRs. Members volunteered to lead the review and conduct the assessment for TR needs (see 

table below). BC volunteered to lead more reviews than the other members. The LS is anticipating an 

additional member on Livestock, so each person will have about 2-3 sunsets. The NOSB Chair asked for 

other Chairs to take note of the overall workload across Subcommittees. 

• Additional Items. None. 

• The meeting was adjourned

Discussion

• January 17, 2023 notes were accepted as written

• 2025 Sunset: Alcohols: Ethanol, Isopropanol (NPP). The lead summarized the two alcohols noting they 

are powerful and benign sanitizers in wide use. He also noted they have minimal environmental issues. 

The lead will finalize the review and submit them to the NOP for the Spring meeting.

• 2025 Sunset: Glycerin(e) (KH). The lead summarized the uses, history, and manufacture of glycerin. The 

LS included a couple questions for stakeholder comment and the lead will submit the document for the 

Spring meeting. 

• 2025 Sunset: Mineral oil (BC). The lead summarized the use and potential issues with mineral oil, noting 

that it is benign, and it is also a highly purified petroleum distillate. The group discussed the two 

different listings - which essentially separate them into internal and external use. The lead suggested 

some questions for public comment and will submit the review for the Spring meeting. 

• 2025 Sunset: Biologics - Vaccines (BC). The lead summarized the draft review and highlighted some 

areas for discussion, particularly excluded methods. Members support the idea that vaccines are 

essential for humane treatment of animals. The LS discussed the listing and the language in OFPA at 

§ 205.102. 

• Additional Items. None.

• The meeting was adjourned
