Very possible. I am not fully convinced. The dog had to identify the people who had food in there bags, and tell them apart from all the people who used to have food in those same bags, or were eating on the flight and have food on there breath or hands. A dog trying to identify (for example) canabis would probably have an easier time.
My stance is not “I know 100% that sniffer dogs are a silver bullet”, but the weaker position “The majority of the value of a sniffer dog comes from it actually smelling things, rather than giving the officer controlling it a plausible way of profiling based on other (possibly protected) characteristics.”
