Jerky statistics span two very different subjects: a major FDA investigation into jerky pet treats and FSIS guidance for making meat and poultry jerky safely. The figures below keep those subjects separate while showing what the reported cases, preparation temperatures, storage periods, and validated pathogen-reduction processes actually measured.

Reported jerky pet-treat cases
The FDA’s report, “FDA Investigates Animal Illnesses Linked to Jerky Pet Treats,” describes complaints received through December 31, 2015. These are reported illness figures associated with chicken, duck, or sweet potato jerky treats; they should not be read as a confirmed cause for every complaint.
By that date, the FDA had received approximately 5,200 complaints. Those complaints involved more than 6,200 dogs, 26 cats, and 3 people. They included more than 1,140 reported canine deaths. The FDA had been receiving reports of pet illnesses associated with jerky pet treats since 2007.
The distribution of reported cases was also uneven:
- About 60% involved gastrointestinal illness, with or without elevated liver enzymes.
- About 30% involved kidney or urinary signs.
- The remaining 10% involved convulsions, tremors, hives, or skin irritation.
The report says reported cases had not exceeded 100 per quarter during the prior 1.5 years. That quarterly observation is a description of the reporting pattern, not a measure of all jerky consumption or all illnesses among pets.
One specific clinical pattern appeared in more than 360 dogs reported since 2007: glycosuria with normoglycemia, which the FDA described as characteristic of Fanconi syndrome. The date range matters here because the figure accumulates reports over several years, while the approximately 5,200 complaints figure is stated as of December 31, 2015.
The FDA also described a case-control study focused on kidney illness. It identified about 100 dog kidney-illness cases reported since July 1, 2013, then sought approximately 3 control dogs in the same geographic region for each sick dog case. More than 12,000 phone calls were needed to identify fewer than 300 controls. These numbers describe the study’s recruitment effort; they do not establish a prevalence rate for kidney illness.
What the FDA tested
The FDA’s sampling figures show the scale and variety of the investigation. It had collected approximately 530 jerky treat samples tied to more than 290 consumer complaints. It had also collected more than 450 retail jerky treat samples, defined in the report as unopened bags from stores or shipments.
During fiscal year 2014, Vet-LIRN tested 71 investigative jerky pet-treat samples. Of those samples, 27 tested positive for amantadine. The FDA also said nearly all measurable antibiotic levels found in jerky treats were below 0.0001%, or below 1 part per million.
Testing and regulatory activity changed over time. Products were removed from the market in January 2013 after a NYSDAM study found low antibiotic residues. The FDA said some jerky-treat brands returned to the market in February 2014 after formulation changes. In 2015, the FDA expanded testing to include duck jerky, and that testing detected antibiotic and antiviral residues in an imported duck jerky product. The Import Alert was revised in October 2015 to include all poultry jerky-type pet treats.
The testing plan covered several categories rather than one single contaminant. It listed 4 pathogenic-bacteria groups, including Salmonella, Bacillus cereus, Staphylococcus aureus, and Clostridium perfringens. It listed 3 antibiotic classes—sulfonamides, quinolones, and tetracyclines—and 4 antivirals, including amantadine, rimantadine, and oseltamivir. It also listed 3 metals or elements: arsenic, cadmium, and lead.
Other categories included 2 irradiation markers, such as 2-alkylcyclobutanones, and 3 rodenticide-related categories or compounds: rodenticides, melamine, and related triazines among nephrotoxins. These are test-plan categories in the FDA report, not a statement that every category was found in every product.
Home jerky temperatures and yield
For home cooks, the FSIS page “Jerky and Food Safety” gives several practical numbers. FSIS says raw meat or poultry dehydrated at home can retain pathogens when held at 130°F to 140°F in a food dehydrator. Its recommendation is to heat meat to 160°F before drying jerky and poultry to 165°F before drying jerky.
Those preheating targets are especially useful when working with wild game or other lean meats, because drying alone is not treated as the complete safety step in this guidance. The temperature figures refer to the FSIS recommendation; they are not a guarantee that every appliance or slice reaches the same internal temperature without checking the process.
Jerky yield is much lower than the starting weight of fresh meat. FSIS says 1 pound of meat or poultry weighs about 4 ounces after becoming jerky. That is a four-to-one weight change in the stated example, useful when planning how much raw meat to prepare for a batch.
The basic temperature comparison is compact:
| FSIS measure | Temperature or result |
|---|---|
| Raw meat before drying | 160°F |
| Raw poultry before drying | 165°F |
| Dehydrator range identified as potentially retaining pathogens | 130°F–140°F |
| Fresh meat starting weight | 1 pound |
| Approximate finished jerky weight | 4 ounces |
Storage and raw-meat timing
FSIS distinguishes between commercially packaged jerky and home-dried jerky. Commercially packaged jerky can be kept for 12 months, while home-dried jerky can be stored for 1 to 2 months. These are the periods stated on the FSIS “Jerky and Food Safety” page, and they should not be blended into one general shelf-life number.
Before drying, FSIS recommends keeping meat and poultry refrigerated at 40°F or slightly below. Ground beef and poultry should be used or frozen within 2 days. Whole red meats should be used within 3 to 5 days.
The preparation timeline therefore has separate controls: refrigeration before processing, a pre-drying heat step, drying, and a storage period matched to whether the product is commercially packaged or made at home. The statistics do not provide a universal storage time for every recipe, thickness, package, or water-activity result, so those details should not be inferred from the headline periods.
The FSIS Jerky Guideline adds a water-activity boundary for packaged products. Vacuum-packaged products with water activity greater than 0.85 and up to 0.91 should be refrigerated after opening. The guideline also notes that products above 0.83 under aerobic conditions or above 0.90 under anaerobic conditions can support Staphylococcus aureus growth limits from its cited reference. FSIS recommends an upper limit of 0.85 for supporting shelf stability.
Pathogen-reduction standards
The FSIS Jerky Guideline expresses lethality as a log10 reduction. For meat and poultry jerky, the guideline says the process should achieve at least a 5.0-log10 reduction of Salmonella species. For products containing beef, it also specifies at least a 5.0-log10 reduction of Shiga toxin-producing E. coli (STEC). Poultry jerky should achieve at least a 5.0-log10 reduction of Salmonella, while the guideline notes a 7.0-log10 Salmonella reduction performance standard for poultry jerky, with an alternative equivalent lethality allowed.
The guideline says meat and poultry jerky should achieve at least a 3.0-log10 reduction in Listeria monocytogenes. A 5.0-log10 reduction or greater is described as desirable for an additional Listeria safety margin. These targets are process-performance measures, not percentages of finished batches.
FSIS gives several humidity options. Continuously introduced steam can be used for 50% of the cooking time, or a sealed oven can be used for more than 50% of the cooking time. Another option uses 90% relative humidity for at least 25% of total cooking time, and that 90% humidity period can never be less than 1 hour. The humidity option applies when the product reaches 145°F for 4 minutes.
The guideline also says that preheating jerky strips in marinade to 160°F provides an immediate reduction of Salmonella. For uncured poultry, it lists 160°F as the minimum internal temperature. For cured and smoked poultry, it lists 155°F.
Validated processing examples
Attachment 2 to the FSIS Jerky Guideline reports several validated process examples. These examples include staged temperatures, humidity or time observations, and measured log10 reductions. They are process examples from the attachment, not a substitute for validating a different dehydrator, slice thickness, formulation, or batch size.
One whole-muscle beef jerky process used 145°F in stage 1 and 170°F in stage 2 with a 125°F wet bulb. Its stage 3 dry bulb was 170°F. Across reported variants, the listed times were 15, 15, at least 60, at least 60, at least 30, and at least 10 minutes. The corresponding reductions across variants were 6.5, 6.9, 7.0, 6.9, 6.9, 7.1, 7.1, and 7.1 log10.
Another validated process used 145°F in stage 1, followed by a stage 2 sequence using a 150°F or 190°F dry bulb and a 130°F wet bulb. The tested variants used 15 minutes and 60 minutes to targeted doneness; the report’s time column included 56 and 19 minutes for those variants. The reported reductions were 6.8, 7.1, 7.0, and 7.3 log10.
The attachment also reports these process types:
| Process | Key conditions reported | Measured reductions |
|---|---|---|
| Type 2 | 145°F and 170°F; 15 minutes to targeted doneness; 27%–31% humidity at start and 17%–21% at end | 6.3-log10 Salmonella; 6.0-log10 E. coli O157:H7 |
| Type 3 | 145°F and 170°F; 90% humidity to targeted doneness; 41 minutes at start and 21 minutes at end | 5.5-log10 Salmonella; 5.6-log10 E. coli O157:H7 |
| Type 5 | 180°F to targeted doneness; 29 minutes at start and 15 minutes at end | 5.1-log10 Salmonella; 5.6-log10 E. coli O157:H7 |
| Type 7 | 120°F, 130°F, 140°F, and 170°F; 60 minutes at each stage | 6.0-log10 Salmonella; 5.6-log10 E. coli O157:H7 |
For the type 7 process, the report table also included humidity or time values of 43 and 15. The attachment does not turn these examples into one universal cooking schedule. Instead, the figures show why temperature, humidity, time, product type, and targeted doneness need to be considered together when evaluating a jerky process.
