A-133 audit requirement for food banks

[M.Kander@att.net]

Does anyone know if food banks at the sub-recipient level are required to undergo an A-133 audit if they distribute more than $500,000 in commodities under USDA CFDA 10.568/9 or if those commodities plus other government grants exceed $500,000?
These organizations are often churches and local community centers. It seems that the audit requirement should apply at the state level but not the sub-recipient level, but I am not able to find any guidance. Thanks. Mike
