Safe, high-quality beef

There is nothing more important than ensuring the beef your family and our families enjoy is safe to eat. That's why we are so rigorous in our product evaluation and so passionate in our support of cattle farmers and their commitment to provide safe, quality beef for you and your family.

Five reasons you can trust the safety of beef from cattle fed Zilmax:

1. FDA approved: Tested and verified as safe

More than 30 years of research and development, as well as rigorous testing, support the safety of Zilmax. Before an animal health product is approved, the authorities at FDA scrutinize the research, review the data and assess multiple safety aspects before concluding that beef from cattle fed Zilmax is safe to eat and poses no risk to human safety.1

2. Doesn't accumulate in the muscle or fat

In addition to various food safety and toxicology tests, the very nature of this supplement means that it breaks down and is metabolized by the animal's system. As a result, it clears from the animal quickly and does not accumulate in the muscle or fat.

3. Track record of safety

Before Zilmax was approved for use in the U.S., it already had a solid track record of safety in other countries, some of which have used the product for 20 years. In all that time, there have been millions and millions of meals served with beef from animals fed Zilmax and not a single food safety incident.

4. An expert point of view

"When we talk technologies, we need to talk 'Is it safe for humans?' 'Is it safe for the animals?' and 'Is it safe for the environment?' And, I think the track record with beta-agonists that have been used for quite a while in the United States proves that those three safety factors are there." Richard Raymond, M.D.,
Former USDA Food Safety Undersecretary

5. Growing global acceptance

As consumers in developed and developing countries want to increase the beef in their diets, more countries are interested in registering this product for use. Zilmax helps increase the supply of quality lean beef to feed the billions of consumers globally who seek increasing amounts of protein in their diets. We work with the scientific regulatory agencies in those countries to provide the necessary research and background for review. To date, in addition to the U.S. and Canada, 14 other countries have already registered the product for use, and eight other countries are in the process of reviewing information required for registration.


Zilmax registration is approved in: Brazil, Canada, Colombia, Costa Rica, Dominican Republic, Ecuador, Guatemala, Honduras, Kazakhstan, Mexico, Nicaragua, Panama, Peru, South Africa, South Korea and United States. Registration is in process for Zilmax in eight additional countries: Argentina, Australia, Chile, Indonesia, New Zealand, Pakistan, Taiwan and Uruguay.
