Hi joanne,
I’ve fed Purina for for about 20 years now and have never had insect infestation in any of the bags I’ve purchased over the years.
On the other hand it wouldn’t surprise me that you’ll get many hits if you search “Purina and worms or bugs” because of the large volume is sold. If there is a one in a million problem and 100 million units sold that makes for 100 problems vs a company with smaller distribution of 500,000 units will only experience the one in a million problem once every 2 years.
Insect activity is a post production problem often related to storage both at the distribution center and in the home.
The same reasoning applies to reports of illness. The greater the population using a product the more reports of illness which may or may not be related to the product will be reported.
