Fast food is bad for health. Yup, I agree 100 percent.
These fast food chains make it worse by adding preservatives. Yup, again agreed.
( but they NEED to add preservatives as they cant buy their supplies locally )
But remember, taste also matters. ( those who say it smells and tastes same , have either never smelled them ( let alone taste it) or doesn't have tastebuds)
I personally like KFC's original chicken ( not the grilled or juicy one , thats nothing special) a lot , also the zinger burger and choco-lash( other similar lashes). Its very unique and original, have tried making them but i just cant get that hard crunchy part ( have tried corn-egg-bread-rice- everything that can make it crunchy . so don't say unless you have tried)
Among others , nothing is as good as KFC (IMO) , i prefer to make by own pizza if i have a oven at hand, but pizzahut / dominos also do when i/friends feel like having a pizza. For burgers, as said before i prefer zinger, i dont like mcdonalds unless maharaja mac is prepared fresh. Others are nothing special. Oh and a special mention for WIMPY, they had the BEST chicken burgers, sad wimpy is no more in india. I am talking about Fast food restaurants only.
Now, about this thread,
With the amount of preservatives they add its very unlikly that worms can have a happy habitat in there, my guess is that they dint store it properly/neglected its storage. Yup its KFC's fault for not keeping that in check but as far as i know these big chain firms are very strict on these things( for obvious reasons, look here it happened in kerala we are discussing it here, no one would have cared if it was Raju's chicken )
It can happen again in future, so what can be done ? Dont eat at any KFC ever ? That would be stupid , if you go by that logic you cant even eat at home.
so
1. Eat in a well hygienic restaurant , if you can check their kicthen.
2. A rotton food/ worm infested food WILL taste and smell like a rotton/worm infested food.
3. Always check if they have put fresh veggies in in the dish ( lattuce , tastes good fresh , dont accept dull one, it will ruin the dish)
4. Dont eat just for the sake of it. Eat when you want to eat. ( specially at FastFood restaurants)
5. Yup, as the op said report if threre are serious issues. If you dont have number of authorities, just dial 100.
