d. government inspectors had the authority to shut down the food production at any time.

Explanation:

After the 1992 E. coli outbreak at Jack in the Box, David M. Theno implemented safety measures. One key measure was having record - keeping thermometers in refrigerated delivery trucks. This helps monitor temperature (a critical factor in preventing bacterial growth) during food transport. Option B about meat slaughter location was not the main safety standard from Theno. Option C about multiple microbial testing of employees during a shift is not a standard associated with Theno's post - outbreak measures. Option D about government inspectors' shutdown authority was not a new measure specifically implemented by Theno at Jack in the Box after this outbreak.

Answer:

A. All refrigerated delivery trucks were required to have a record - keeping thermometer mounted inside.
