I know there are no standards when testing for lactic acid in foods especially since it's concerning spoilage. But has anyone come across limits for lactic acid in low pH foods.

Just to share, we initially apply the local TPC standard then after enough data are collected we set our own in-plant limits. But usually, lactic acid bacteria have difficulty in adapting with below 3 ph. I would recommend to check your historical data or collect data to analyze and set limits.

Ok, I'm going to assume you're making an acidified shelf stable something (correct me if i'm wrong on this)

 

The pickle bibliography is an absolute wealth of information  and you may find what you seek there
