A new pesticide can now be used on food without safety limits
What happened
US environmental regulators just exempted a new polypeptide from safety limits on food and feed. This means the pesticide can be used on all crops without a maximum residue level.
Why it matters
Every pesticide used on food in the US must meet a "tolerance" — a maximum amount of residue allowed on crops. This rule means a new biological pesticide, ASFBIOF01-02 polypeptide, does not need to meet that standard. It can be used without any limit on how much residue remains on food.
The signal
Watch for other biological pesticides to seek similar exemptions, setting a precedent for how these new compounds are regulated.
