However, he noticed that the people had maintained the same traditional method of processing cassava into garri for ages, including the storage method. This method posed some safety concerns because, as the unpackaged garri moved from person to person, it was exposed to many dirty hands. In some cases, rats would defecate on it, yet it would still be consumed, even if the consumer was aware of the contamination. He also discovered that at the markets where garri was sold, the food was exposed to pecking flies, cold and wet weather, sneezes from sick people or allergic reactions, footwears carrying sand, lizards, pet animals, and more.

a person in a foreign country must integrate into the local community, otherwise they can only wait to be excluded by the locals. this has nothing to do with whether to uphold tradition, he always has to find a way to survive living in unfamiliar land. and no one wants their hometown to become an unfamiliar land and then become someone who, although still living in their hometown, is actually homeless in their hearts.
most people are willing to accept gentle and slow change, but the example you gave is too inappropriate. Is it possible that everyone just doesn't like packaging garri, or more likely, packaging garri itself is not as cheap and delicious as locally processed and unpackaged garri.

Come on! O, it's the word "tradition" that's confusing you. Sometimes, read twice for understanding. Well, in the simplest of terms, tradition in this context means "the old casual way of doing things" which in this context is unhealthy and not the "worship of gods, or marriage rites, or whatever" you're thinking as tradition. For instance, eating garri is the norm of the people and it is also a tradition. However, the process of preparing and storing it is not hygienic, and advancing on that would not stop you from eating garri which is the core tradition, neither did it change the tradition of selling garri however, it will advance on its preparation and storage which will be more healthy. Look at AC generators of today, they're far different from old generators but they're serving the same purpose. A 5kw generator used to be very large but today the size is twice smaller than the old ones, yet still producing the same power, now this change in size would save space and also the sound ain't as high as the old ones. This is what this professor was trying to explain, and it is clearly because we lack scientists in the government sector that will educate the public on the dangers of some "traditions". This attitude also affects the Nigerian politics, and national security as well as prosperity. Even politicians and many of you were still thinking that despite using an advanced election method that without party structure, one would loose elections, but people without structure were among the top 4 (something that has never happened in Nigeria), in fact, INEC has to switch of their IREV just to maintain the "Tradition" because something shocking was about to occur. Do you understand? Chai! My guy... Abeg think, think, think! No be everything we go wan argue to prove point.
