Food safety should always be throughout the food chain, one break on the chain will result in compromising the safety of a food product.
It is not just odd that a packaging manufacturer is required to dorn on hair net while an institutional staff is not, it is not right.
But IMO, it is something that hopefully time will remedy as the awareness and the enforcement is not quite there.
What happens is the manufacturer may be doing something to assure food safety, but the next person down the line is not, such as the distributors and retailers. And we are putting much attention on the manufacturers...easier targets perhaps, everything should start with them perhaps.
I came across a spice supplier who would ask their customers to store the spices at a certain temperature, but they themselves are not practising it in the warehouse.
The public would shake their heads and refrain from buying products from a certain manufacturer whose products have been linked to a case, but then turn to frequent local roadside stalls that hang by the rule of one multipurpose wiping towel...
Just comes back to the one possible solution, public awareness and public call for such minimum requirements to be inplace, right now, many of the public are just not bothered.
