Introduction

The Agency has determined that all necessary product chemistry information is either 

available or has been waived for the pesticide active ingredient meat meal. The Agency

has also determined to waive all of the human health data requirements based on 

submitted information, and the Agency has determined to waive all of the ecological data 

requirements based on submitted information.

Meat meal is a sterilized, animal food by-product produced from animal proteins at livestock 

rending plants. It is used as an animal food/feed supplement, an organic fertilizer and as an 

animal repellent. Meat meal is used as a powder which is sprinkled around the perimeter of the 

planted area and around the base of plants at a rate of one pound per 75–100 square feet. Meat 

meal is also used a as powder in bags and placed around the perimeter of ornamental and 

agricultural areas. Like the action of most animal repellents, meat meal is used to repel animals 

in an olfactory manner. The first product containing this active ingredient was registered with the 

Agency in 1996. Currently, there is one registered product containing meat meal which is an 

end-use product (EP). Meat meal is intended to repel animals such as deer, rabbits, raccoons, and 

other wild-life from damaging ornamental and agricultural crops. 

PRODUCT CHEMISTRY AND PRODUCT IDENTITY

Concerning the product chemistry of meat meal, all biochemical pesticide data requirements for 

the active ingredient have been satisfied with data or have been waived and are summarized in 

Table 1.

Product Chemistry Summary 

The Agency has conducted reviews of the available product chemistry data and information for 

meat meal. During the registration of the active ingredient, meat meal, the registrant submitted 

waiver rationales for some of the product chemistry and the physical and chemical 

characteristics. The rationales were accepted by the Agency. These data are summarized in Table 

2, below.

Human Health

EPA’s preliminary review of the available human health data/information on record show that 

the acute oral toxicity, acute dermal toxicity, acute inhalation toxicity, primary eye irritation, 

primary dermal irritation and dermal sensitization data requirements have not been adequately 

addressed. Data gaps have been identified for meat meal (indicated with a “Data Gap” 

designation in Table 3) based on the inadequacy of the data/information submitted. EPA will 

make the determination as to whether additional data/information will be required in the final 

work plan. Table 3 reflects biochemical data requirements and either anticipated data needs or 

the fulfillment of the human health data requirements for meat meal (U. S. EPA, 2013).

Tolerances

No tolerance or exemptions are associated with the use of this biochemical pesticide because it is 

not applied directly to vegetation and therefore, all uses are non food uses. 

Incidents

During the timeframe from December 1, 1996 to May 15, 2013, there were no incidents 

reported from the use of meat meal to The National Pesticides Information Center (NPIC)

database, The Office of Pesticide Programs' Incident Data System (IDS) or The Environmental 

Incident Information System. No adverse effects to humans, domestic animals, or the

environment were reported as a result of the use of meat meal as an animal repellent.

Table 3. Human Health Values for Meat Meal (40 CFR § 158.2050)

Ecological Toxicity and Endangered Species

EPA’s preliminary review of the available ecological toxicity data/information on record 

shows that the ecological toxicity data requirements have not been adequately addressed. The 

EPA considers the inadequacy of the data/information on record to be a data gap for the listed 

studies. Data gaps have been identified for these data requirements (indicated with the Data Gap 

designation in Table 4) based on the inadequacy of the data/information submitted. 

F. Endangered Species

The EPA has not prepared a risk assessment that supports a complete endangered species 

determination for meat meal. During Registration Review, the EPA plans on conducting an 

ecological risk assessment to determine whether use of meat meal will have “no effect” or “may

affect” federally listed threatened or endangered species (listed species) and/or their designated 

critical habitat. When an assessment concludes that a pesticide’s use “may affect” a listed species 

and/or its designated critical habitat, the EPA will consult with the U.S. Fish and Wildlife 

Service and/or National Marine Fisheries Service (the Services), as appropriate.
