Is the beef grass-fed or grass-finished?

The brand specifies: "100% forage from weaning to harvest, no grain finishing, ever." The USDA withdrew its grass-fed claim standard in 2016, and there is no binding federal definition in the US. Paraguay has no legal definition either. Without "finished" (or "100% pasture through harvest"), grass-fed can include weeks or months of grain at the end, which erases the omega-3, CLA, and fat-soluble vitamin benefits. The American Grassfed Association (AGA) is the strictest standard and requires lifetime forage only.

What does the animal eat during the dry season?

Native hay from the same farm, or stored forage with no grain. The detail is published. The Paraguayan Chaco dry season (June–October) pressures producers to supplement. Many "grass-fed brands" use corn silage or formulated feed during those months without disclosing it. An honest answer names the specific forage (alfalfa, oats, Gatton panic, field hay) and explains how seasonal stock is managed.

Does the feed come from the same farm, or is it imported?

Feed from the producer's own land, rotated pastures named by species. Paraguay imported over 16,000 tons of Brazilian beef in 2025 and undisclosed quantities of formulated feed. The Brazilian feed market has had documented contamination episodes. A serious Paraguayan grass-fed brand doesn't need to import anything, the right question is: did the grass the animal eats grow on the same land it lives on?

Do they publish the full vaccine list, what they use and what they don't?

Explicit public list. Only foot-and-mouth (twice yearly, SENACSA-mandated) and brucellosis RB51 in breeding females. Nothing else. SENACSA mandates foot-and-mouth vaccination twice yearly and brucellosis in breeding females; the rest is discretionary. Industrial brands often add BVD, IBR, leptospirosis, campylobacter and other reproductive vaccines. There are no commercial mRNA cattle vaccines in Paraguay as of 2026, a brand that commits to not using them (if approved) is being thoughtful; a brand that refuses to publish its full list is hiding something.

Do they use routine or prophylactic antibiotics?

Only individual treatment of sick animals, by veterinary prescription, with that animal leaving the program permanently. The WHO identifies prophylactic use in healthy animals as a primary driver of antimicrobial resistance. In the US, the 2017 Veterinary Feed Directive eliminated antibiotic use for growth promotion, prophylactic use remains permitted under veterinary supervision. In Paraguay, the framework is less rigorous: oversight depends on the producer.

If an animal needs antibiotics, does it return to supply after a withdrawal period, or leave permanently?

Leaves permanently. The treated animal is never part of the program again. The "withdrawal period" is the legal interval between the last antibiotic and slaughter, designed to let residues fall below limits. A 2023 FSIS sampling study found residues in ~20% of liver and kidney samples from cattle labeled "Raised Without Antibiotics" at 84 slaughter establishments, verification is the Achilles' heel. The AGA standard requires permanent removal, not a withdrawal period.

Do they use growth hormones, implants, or beta-agonists (ractopamine, zilpaterol)?

Zero. They publish the explicit list of what they don't use. The FDA approves 7 hormonal compounds for US cattle, estradiol, progesterone, testosterone, trenbolone, zeranol, melengestrol acetate, rBST. Per the most recent USDA-APHIS national survey (NAHMS 2011), 90%+ of US feedlot cattle receive at least one implant. The EU has banned them since 1988. Ractopamine is banned in more than 160 countries (EU, China, Russia). Paraguayan beef exported to the EU must be hormone-free; the Paraguayan domestic market does not have the same public requirement.

Does the animal spend any part of its life in a feedlot or confinement?

Never. Paddock rotation from birth to harvest. The CAFO (Concentrated Animal Feeding Operation) model is efficient at producing cheap meat quickly, but introduces stress, density-driven disease, and the need for prophylactic antibiotics. The AGA standard prohibits it outright. In Paraguay many "premium" brands finish on grain in pens during the last months, a practice that's hard to verify if not published.

Which animal-welfare standard do they adhere to?

Explicit reference to Temple Grandin, the Five Freedoms, or AGA. Published protocols. The Five Freedoms (UK FAWC, 1979) are the universal baseline for animal welfare. Temple Grandin developed the practical low-stress handling standards that roughly half of the North American beef industry follows. Paraguay has no codified welfare regulation; the topic is left to voluntary programs like ARP's Carne Natural. Without a reference framework, any brand can say "we treat well" without accountability.

What's the stocking density per hectare and the paddock rotation cadence?

Concrete numbers (e.g., "0.8–1.2 head/ha, rotation every 25–35 days"). Explanation of pasture rest. Stocking density determines welfare, soil health, and sustainability. An industrial operation can run 3–4 head/ha in the Chaco with visible pasture degradation; a serious operation runs <1.5 head/ha with rotation. Asking for the specific number quickly exposes who speaks in generalities.

Do they publish the slaughterhouse where harvest happens and its SENACSA approval number?

Facility name + public SENACSA approval number. Paraguay has a short list of slaughterhouses approved for EU and Russia exports, they meet higher standards than domestic-tier plants. A brand that hides its facility could be harvesting at a lower-tier plant. In 2024, Global Witness linked a Paraguayan slaughterhouse to illegal deforestation and violation of Ayoreo ancestral land, plant transparency matters.

Are aging method and duration stated on every cut's label?

Type (wet/dry) + days stated on every package. No exceptions. Dry aging (14–28 days in a cooler) concentrates flavor and improves tenderness at the cost of yield from evaporation. Wet (vacuum) aging (7–14 days) is more efficient but different. Both are valid, opacity isn't. If the seller can't tell you how many days your steak was aged, they're charging premium without delivering transparency.

Any post-harvest chemical treatment? (carbon monoxide, ammonia, meat glue, water injection)

Plain vacuum packaging, no gases, no solutions, no additives. Whole-muscle only. Carbon monoxide modified-atmosphere packaging (MAP CO) keeps meat cherry-red even after weeks, FDA GRAS since 2002, banned in the EU since 2003. Ammonium hydroxide is used in pink slime (LFTB). Transglutaminase ("meat glue") bonds trimmings into what looks like whole steaks, legal in Paraguay and the US, banned as a binder in the EU since 2010. Water injection (up to 15% of billed weight) is legal with labeling in the US.

Does the package carry a lot code linking to the specific animal, ranch, and slaughter date?

Yes. They can tell you exactly which animal your cut came from. SENACSA launched SIAP (Sistema de Identificación Animal del Paraguay) in December 2023 under Law 7221; individual identification will be mandatory for the full national herd by 2026. SITRAP already existed for EU-export traceability. A serious brand uses one of these systems to trace every cut; one that doesn't is running on group-level rather than animal-level traceability.

Third-party audit, or enrollment in a verifiable program?

Certification by Control Unión, LETIS, or audited enrollment in ARP's Carne Natural program. They publish the document. Paraguay has no national organic-beef certifier. The gap is filled by international auditors (Control Unión, LETIS) certifying against EU/USDA/NOP standards, plus the local voluntary Carne Natural program from ARP. A brand that calls itself "certified" without naming the auditor is using the word as a synonym for "we said so", nothing more.

Buyer's guide

How to evaluate any premium beef brand

15 diagnostic questions that separate real standards from marketing. Works with any brand, including ours.

Last reviewed: April 22, 2026

12 min read

In Paraguay, "premium," "organic," and "grass-fed" are marketing terms, there's no law that defines them, and no regulator that systematically audits them. SENACSA regulates animal health and export slaughterhouses; it does not define what grass-fed means, and does not require any brand to publish how its cattle are raised. The gap is filled with labels and pretty photography.

This guide gives you 15 concrete questions that separate real standards from marketing. It works with any brand, ours included. If a brand cannot answer these questions publicly, with detail, it's probably using Paraguay's regulatory gap in its favor.

What the animal eats

Diet determines the nutritional profile and ~90% of the real quality differentiators.

01 Feed

Is the beef grass-fed or grass-finished?

What a strong answer looks like

The brand specifies: "100% forage from weaning to harvest, no grain finishing, ever."

What a weak answer looks like

Uses only "grass-fed" or "pasture-raised" without clarifying grain finishing.

Why this question matters

The USDA withdrew its grass-fed claim standard in 2016, and there is no binding federal definition in the US. Paraguay has no legal definition either. Without "finished" (or "100% pasture through harvest"), grass-fed can include weeks or months of grain at the end, which erases the omega-3, CLA, and fat-soluble vitamin benefits. The American Grassfed Association (AGA) is the strictest standard and requires lifetime forage only.
02 Feed

What does the animal eat during the dry season?

What a strong answer looks like

Native hay from the same farm, or stored forage with no grain. The detail is published.

What a weak answer looks like

No answer, or a pivot to "balanced feed."

Why this question matters

The Paraguayan Chaco dry season (June–October) pressures producers to supplement. Many "grass-fed brands" use corn silage or formulated feed during those months without disclosing it. An honest answer names the specific forage (alfalfa, oats, Gatton panic, field hay) and explains how seasonal stock is managed.
03 Feed

Does the feed come from the same farm, or is it imported?

What a strong answer looks like

Feed from the producer's own land, rotated pastures named by species.

What a weak answer looks like

Purchased formulated feed, especially if imported from Brazil.

Why this question matters

Paraguay imported over 16,000 tons of Brazilian beef in 2025 and undisclosed quantities of formulated feed. The Brazilian feed market has had documented contamination episodes. A serious Paraguayan grass-fed brand doesn't need to import anything, the right question is: did the grass the animal eats grow on the same land it lives on?

What the animal is given

Hormones, antibiotics, growth promoters. What goes into the animal's body goes into yours.

04 Vaccines

Do they publish the full vaccine list, what they use and what they don't?

What a strong answer looks like

Explicit public list. Only foot-and-mouth (twice yearly, SENACSA-mandated) and brucellosis RB51 in breeding females. Nothing else.

What a weak answer looks like

Total silence, or vague claims like "only necessary vaccines."

Why this question matters

SENACSA mandates foot-and-mouth vaccination twice yearly and brucellosis in breeding females; the rest is discretionary. Industrial brands often add BVD, IBR, leptospirosis, campylobacter and other reproductive vaccines. There are no commercial mRNA cattle vaccines in Paraguay as of 2026, a brand that commits to not using them (if approved) is being thoughtful; a brand that refuses to publish its full list is hiding something.
05 Antibiotics

Do they use routine or prophylactic antibiotics?

What a strong answer looks like

Only individual treatment of sick animals, by veterinary prescription, with that animal leaving the program permanently.

What a weak answer looks like

Feed-grade additions, preventive treatment of whole lots, or "responsible use" with no detail.

Why this question matters

The WHO identifies prophylactic use in healthy animals as a primary driver of antimicrobial resistance. In the US, the 2017 Veterinary Feed Directive eliminated antibiotic use for growth promotion, prophylactic use remains permitted under veterinary supervision. In Paraguay, the framework is less rigorous: oversight depends on the producer.
06 Antibiotics

If an animal needs antibiotics, does it return to supply after a withdrawal period, or leave permanently?

What a strong answer looks like

Leaves permanently. The treated animal is never part of the program again.

What a weak answer looks like

"Yes, after the legal withdrawal period", that's the industrial standard.

Why this question matters

The "withdrawal period" is the legal interval between the last antibiotic and slaughter, designed to let residues fall below limits. A 2023 FSIS sampling study found residues in ~20% of liver and kidney samples from cattle labeled "Raised Without Antibiotics" at 84 slaughter establishments, verification is the Achilles' heel. The AGA standard requires permanent removal, not a withdrawal period.
07 Hormones

Do they use growth hormones, implants, or beta-agonists (ractopamine, zilpaterol)?

What a strong answer looks like

Zero. They publish the explicit list of what they don't use.

What a weak answer looks like

Silence, or vague "export-quality" claims without specifics.

Why this question matters

The FDA approves 7 hormonal compounds for US cattle, estradiol, progesterone, testosterone, trenbolone, zeranol, melengestrol acetate, rBST. Per the most recent USDA-APHIS national survey (NAHMS 2011), 90%+ of US feedlot cattle receive at least one implant. The EU has banned them since 1988. Ractopamine is banned in more than 160 countries (EU, China, Russia). Paraguayan beef exported to the EU must be hormone-free; the Paraguayan domestic market does not have the same public requirement.

How the animal lives

Stress, handling, and space directly affect the quality of the final meat.

08 Handling

Does the animal spend any part of its life in a feedlot or confinement?

What a strong answer looks like

Never. Paddock rotation from birth to harvest.

What a weak answer looks like

"60/90/120-day feedlot finishing", that's the standard industrial model.

Why this question matters

The CAFO (Concentrated Animal Feeding Operation) model is efficient at producing cheap meat quickly, but introduces stress, density-driven disease, and the need for prophylactic antibiotics. The AGA standard prohibits it outright. In Paraguay many "premium" brands finish on grain in pens during the last months, a practice that's hard to verify if not published.
09 Handling

Which animal-welfare standard do they adhere to?

What a strong answer looks like

Explicit reference to Temple Grandin, the Five Freedoms, or AGA. Published protocols.

What a weak answer looks like

Just "we treat our animals well" with no framework.

Why this question matters

The Five Freedoms (UK FAWC, 1979) are the universal baseline for animal welfare. Temple Grandin developed the practical low-stress handling standards that roughly half of the North American beef industry follows. Paraguay has no codified welfare regulation; the topic is left to voluntary programs like ARP's Carne Natural. Without a reference framework, any brand can say "we treat well" without accountability.
10 Handling

What's the stocking density per hectare and the paddock rotation cadence?

What a strong answer looks like

Concrete numbers (e.g., "0.8–1.2 head/ha, rotation every 25–35 days"). Explanation of pasture rest.

What a weak answer looks like

Qualitative answers ("low stocking," "plenty of space") with no numbers.

Why this question matters

Stocking density determines welfare, soil health, and sustainability. An industrial operation can run 3–4 head/ha in the Chaco with visible pasture degradation; a serious operation runs <1.5 head/ha with rotation. Asking for the specific number quickly exposes who speaks in generalities.

What happens after harvest

Every industrial processing shortcut happens at this stage.

11 Slaughter

Do they publish the slaughterhouse where harvest happens and its SENACSA approval number?

What a strong answer looks like

Facility name + public SENACSA approval number.

What a weak answer looks like

"SENACSA-approved" with no facility name.

Why this question matters

Paraguay has a short list of slaughterhouses approved for EU and Russia exports, they meet higher standards than domestic-tier plants. A brand that hides its facility could be harvesting at a lower-tier plant. In 2024, Global Witness linked a Paraguayan slaughterhouse to illegal deforestation and violation of Ayoreo ancestral land, plant transparency matters.
12 Processing

Are aging method and duration stated on every cut's label?

What a strong answer looks like

Type (wet/dry) + days stated on every package. No exceptions.

What a weak answer looks like

"Aged" with no detail. Or aging claimed in marketing but not on the physical label.

Why this question matters

Dry aging (14–28 days in a cooler) concentrates flavor and improves tenderness at the cost of yield from evaporation. Wet (vacuum) aging (7–14 days) is more efficient but different. Both are valid, opacity isn't. If the seller can't tell you how many days your steak was aged, they're charging premium without delivering transparency.
13 Processing

Any post-harvest chemical treatment? (carbon monoxide, ammonia, meat glue, water injection)

What a strong answer looks like

Plain vacuum packaging, no gases, no solutions, no additives. Whole-muscle only.

What a weak answer looks like

"Modified atmosphere" without detail, enhanced-solution meat, "formed" cuts.

Why this question matters

Carbon monoxide modified-atmosphere packaging (MAP CO) keeps meat cherry-red even after weeks, FDA GRAS since 2002, banned in the EU since 2003. Ammonium hydroxide is used in pink slime (LFTB). Transglutaminase ("meat glue") bonds trimmings into what looks like whole steaks, legal in Paraguay and the US, banned as a binder in the EU since 2010. Water injection (up to 15% of billed weight) is legal with labeling in the US.

What you can verify

If you can't verify it, it's marketing.

14 Traceability

Does the package carry a lot code linking to the specific animal, ranch, and slaughter date?

What a strong answer looks like

Yes. They can tell you exactly which animal your cut came from.

What a weak answer looks like

Generic lot code or no visible code.

Why this question matters

SENACSA launched SIAP (Sistema de Identificación Animal del Paraguay) in December 2023 under Law 7221; individual identification will be mandatory for the full national herd by 2026. SITRAP already existed for EU-export traceability. A serious brand uses one of these systems to trace every cut; one that doesn't is running on group-level rather than animal-level traceability.
15 Traceability

Third-party audit, or enrollment in a verifiable program?

What a strong answer looks like

Certification by Control Unión, LETIS, or audited enrollment in ARP's Carne Natural program. They publish the document.

What a weak answer looks like

Generic "certified" with no named auditor.

Why this question matters

Paraguay has no national organic-beef certifier. The gap is filled by international auditors (Control Unión, LETIS) certifying against EU/USDA/NOP standards, plus the local voluntary Carne Natural program from ARP. A brand that calls itself "certified" without naming the auditor is using the word as a synonym for "we said so", nothing more.

Watch these claims

Six marketing traps you have to learn to see

These are the terms most used to project a premium image without delivering the substance. Each one comes with the question that defuses it.

"Grass-fed" or "pasture-raised"

What it means

No legal definition in Paraguay or the US since 2016. May include grain finishing.

The question that defuses it

Is it grass-finished? Pasture from weaning to harvest, no grain?

"Natural"

What it means

In the US, USDA's term only applies to post-slaughter processing, not how the animal was raised. A feedlot animal with hormone implants can legally be "natural." In Paraguay the term is unregulated.

The question that defuses it

Natural in what sense? No hormones, no antibiotics, no grain?

"Hormone-free"

What it means

Technically all beef is hormone-free after processing, endogenous hormones don't survive. The real question is whether the animal got growth implants.

The question that defuses it

No growth hormone implants? No beta-agonists (ractopamine, zilpaterol)?

"Antibiotic-free" / "Raised Without Antibiotics"

What it means

A 2023 FSIS study found residues in ~20% of RWA-labeled cattle, verification is weak. "Withdrawal period met" is different from "never treated."

The question that defuses it

Does a treated animal leave the program permanently, or return after withdrawal?

"Certified"

What it means

Often refers to breed certification (Brangus, Braford), not feed, welfare, or traceability. Breed certification is real but narrow.

The question that defuses it

Certified by whom? Control Unión, LETIS, AGA, or a breed association?

"Export quality" / "carne de exportación"

What it means

Means the facility meets the importing country's standards. It's not an independent certification.

The question that defuses it

Export to which market? EU (hormone-free), Russia, Chile? And is the traceability export-grade or domestic?

What to do with these 15 questions

Bring the questions to any brand you're considering, supermarket, neighborhood butcher, delivery service, or us. The brands that answer with detail are the ones that have something to say. The ones that change the subject, speak in generalities, or bristle at the question are using Paraguay's regulatory gap in their favor. Your palate will notice later. Your budget is already noticing.
