Q: In plan English what is the law against shipping yeast nutient to California and why? Besides Ca. Being a BS. State

A: I have not heard this before. I just made a search, and I find no legal restriction on shipping yeast to California. So send all you want unless you know something I don't know or can't find.

A: There are restrictions on shipping yeast nutrient products to California due to state regulations. The primary reason is that California has stricter environmental and health safety laws compared to many other states.

Yeast nutrients often contain ammonium salts like diammonium phosphate (DAP) or ammonium sulfate. In 1999, the California Air Resources Board (CARB) identified DAP as a chemical known to contribute to air pollution and respiratory issues. Due to these potential health risks, products containing DAP are subject to more rigorous shipping requirements and regulations when sold or distributed in California.

Additionally, California's Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, requires businesses to provide warnings to Californians about exposure to chemicals that may cause cancer, birth defects, or reproductive harm. Some yeast nutrient products might contain trace amounts of heavy metals like lead, which are covered under Prop 65.

To avoid potential legal issues and to comply with California's stricter regulations, many suppliers choose not to ship yeast nutrients directly to California or to include the required Prop 65 warnings on their products. However, the specific restrictions and reasons may vary depending on the exact composition of the yeast nutrient product in question.

It's important to note that while California's regulations might seem burdensome to some, they are designed to protect public health and the environment based on the state's assessment of potential risks.
