Does In-N-Out Use Antibiotic Beef?

4 min read

As of early 2025, In-N-Out has committed to sourcing beef not raised with medically important antibiotics, but it has not provided a public timeline for full implementation. This fresh-only fast-food chain continues to face pressure from consumer groups to provide more transparency on its progress toward this goal.

Quick Summary

In-N-Out announced in 2016 that it would transition to beef raised without antibiotics important to human medicine, but a specific timeline has not been made public. The company uses fresh, 100% USDA ground chuck from its own facilities, without fillers or preservatives. Compared to some competitors, In-N-Out's policy lacks clear implementation details and third-party verification.

Key Points

  • In-N-Out committed to reducing antibiotic use: In 2016, In-N-Out pledged to work with suppliers to reduce the use of medically important antibiotics in its beef.

  • Implementation timeline is unclear: The company has not provided a public timeline for completing its transition to beef raised without routine antibiotics.

  • Fresh, never-frozen meat: In-N-Out is known for its fresh, 100% USDA ground chuck with no additives or fillers, a separate quality measure from its antibiotic policy.

  • Lags behind some competitors: Compared to chains like Chipotle and Panera Bread, which have strong, established antibiotic policies, In-N-Out's policy lacks public accountability and third-party verification.

  • Antibiotics are still permitted for treatment: The policy allows suppliers to use antibiotics to treat sick animals, aligning with animal welfare standards.

  • Consumer advocacy continues: Environmental and health groups are still pressuring In-N-Out for greater transparency regarding its antibiotics policy and implementation progress.

In-N-Out's Commitment and Policy

In March 2016, following pressure from a coalition of public health and environmental groups, In-N-Out announced a significant shift in its meat sourcing strategy. The company stated it was working with its suppliers to “accelerate a move away from the use of antibiotics important to human medicine”. This move came as a response to growing consumer concern and aligns with recommendations from health officials about antibiotic overuse in livestock production. The routine use of antibiotics in healthy animals to prevent illness—a common practice in crowded feedlots—has been linked to the rise of antibiotic-resistant bacteria, or 'superbugs'.

While In-N-Out's commitment was a positive step, it did not specify a timeline for this transition, which drew criticism from advocacy groups. The company clarified that while it would work to reduce antibiotic use, it would still allow for their use to treat sick animals, a standard practice in animal welfare. This leaves a gray area for consumers who want to know if the beef is completely 'antibiotic-free'—a label that doesn't officially exist for meat. In-N-Out has also not published a detailed, publicly available antibiotics policy on its website, unlike some competitors.

The Quality Control Process at In-N-Out

In-N-Out prides itself on a fresh, never-frozen approach to its food, a process that is central to its brand identity. The company operates its own patty-making facilities in California and Texas, giving it direct control over the grinding and forming process. This internal production model is intended to ensure consistent quality and freshness. The beef is 100% USDA ground chuck, with no additives, fillers, or preservatives. However, this internal quality control over additives is separate from its policy regarding the responsible use of antibiotics on its suppliers' ranches.

Comparison of Antibiotic Policies: In-N-Out vs. Competitors

The fast-food landscape has seen varying responses to calls for reduced antibiotic use. Consumer advocacy reports, such as the Chain Reaction report, have graded top restaurants on their antibiotic policies for beef. While In-N-Out has made a verbal commitment, its lack of a clear timeline and third-party auditing has historically placed it behind more transparent competitors in these rankings.

Restaurant Chain Beef Antibiotic Policy Transparency Level Third-Party Verification Progress & Notes
In-N-Out Committed to moving away from medically important antibiotics; allows for treatment of sick animals. Low, lacks publicly available, specific goals or timelines. No mention of a public third-party audit. Initial 2016 commitment but no recent public updates on progress.
Chipotle & Panera Bread Strong policies for sourcing beef raised without routine antibiotics. High; consistently earn top grades on consumer reports. Verified by third-party certifiers. Long-standing leaders in responsible antibiotic use.
McDonald's Phased out routine use of medically important antibiotics for prevention; committed to reducing overall use. Moderate; publishes some policy details but has been criticized for slowing progress on beef. Varies by region; stronger in some markets like the U.K.. Had strong early moves, but recent reports show backtracking on commitments.
Taco Bell Committed to a 25% reduction in medically important antibiotics by 2025. Moderate; announced reduction goals but still in the process of implementation. Specifics on verification are less clear. Made a public commitment with a specific, albeit partial, reduction target.

The Impact of Industry Practices on Public Health

The concern over antibiotic use in livestock is not just about personal preference; it has significant public health implications. The CDC has labeled antibiotic resistance one of the biggest public health challenges of our time. When antibiotics are used routinely and unnecessarily in animal agriculture, it contributes to the development of antibiotic-resistant bacteria. These resistant strains can then transfer to humans through the food chain or the environment, making certain infections much harder to treat.

Fast-food chains wield enormous purchasing power, and their sourcing policies can drive change within the agricultural industry. By demanding beef raised with more responsible antibiotic practices, companies can help shift industry standards toward better animal welfare and public health outcomes. This is why consumer groups continue to push companies like In-N-Out to not only commit but also transparently report on their progress toward eliminating the routine use of medically important antibiotics.

What Does This Mean for Consumers?

For the average consumer, In-N-Out's policy means that while the company is committed to transitioning away from beef raised with medically important antibiotics, that transition may not be complete. The burgers are not labeled as 'antibiotic-free,' and the company does not claim that the animals from which their beef is sourced have never received antibiotics. Instead, the policy is focused on reducing and eventually eliminating the routine, non-therapeutic use of specific types of antibiotics.

Customers who prioritize 100% antibiotic-free beef may need to consider fast-food chains with more explicit and implemented policies, such as Chipotle. Those who value freshness and local production without additives and fillers—which In-N-Out provides—can feel confident in those aspects of their meal, but should be aware that the journey toward a fully responsible antibiotic policy is ongoing. The lack of a public timeline is the primary issue preventing consumers from knowing when, or if, this goal will be fully achieved.

Conclusion

While In-N-Out is celebrated for its commitment to fresh, never-frozen ingredients, its policy on antibiotic use in beef is a work in progress. The company publicly committed to working with suppliers to move away from using medically important antibiotics back in 2016. However, it has not provided a public timeline for implementation or comprehensive details on its progress. This puts it behind some competitors with stricter, more transparent policies. Consumers who are concerned about antibiotic use in their fast food should be aware of this ongoing process and weigh their options accordingly. In-N-Out's commitment to freshness and no additives remains strong, but its journey toward a truly antibiotic-responsible beef supply is still unfolding.
