HayRite Safety — A GRAS-Status Biological Hay Preservative With No Acid Handling

Safety classification

✓ Confirmed Withholding Period: None when used as directed (per HayRite product label).

✓ Confirmed EPA Status: 25(b) exempt minimum-risk pesticide. The active ingredient is a beneficial bacterium that does not require traditional pesticide registration.

What is GRAS Status?
GRAS stands for "Generally Recognized as Safe," a designation established by the US Food and Drug Administration (FDA). When a substance holds GRAS status, it means that qualified experts have evaluated the scientific data and concluded that the ingredient is completely safe for its intended use in animal feed. While Bacillus amyloliquefaciens as a species enjoys broad GRAS recognition for many agricultural and feed applications, DB38-specific regulatory documentation is currently moving through standard channels.
‍
✓ Confirmed GHS Classification: Not classified as hazardous under the Globally Harmonized System.

Operator handling

Recommended handling practices when applying HayRite:

• Avoid eye contact and inhalation of spray mist. Standard hay-handling eye protection and dust mask are recommended during application.
• Wash hands after handling. Routine hygiene is sufficient.
• No acid-resistant gloves required. Standard work gloves are fine.
• No respirator required under normal application conditions.
• No special ventilation required beyond what's normal for tractor cab and hay-shed work.

The Biological Advantage over Propionic Acid
The difference in operator safety between HayRite and chemical preservatives is stark. Traditional propionic acid requires strict safety protocols, including acid-resistant gloves, chemical goggles, and robust ventilation to protect the operator from corrosive fumes and severe skin burns. Furthermore, acid-based preservatives require specialized corrosion-resistant applicator equipment to avoid destroying your baler. HayRite, as a purely biological inoculant, eliminates these hazards entirely. It requires no specialized personal protective equipment (PPE), emits no toxic fumes, and is completely non-corrosive to your expensive baling machinery.

Animal feeding safety

✓ Confirmed Treated hay can be fed immediately after baling, with no withholding period.Confirmed Animal Safety

Beef Cattle: HayRite is completely safe for beef cattle at all life stages, protecting the digestible dry matter needed for consistent weight gain.
‍
‍Dairy Cows: HayRite is safe for lactating dairy cows and blends seamlessly into Total Mixed Rations (TMR) without disrupting rumen function.

‍Horses: HayRite is safe for horses and actively benefits equine respiratory health by suppressing the mould spores that trigger respiratory distress.

⚠ Strain Caveat Most published feeding-effect studies use the H57 sister strain (Ngo et al. 2021; Pan et al. 2022). DB38-specific feeding studies are part of our active research program.
