From the illustrated incidences, you may note that many businesses couldn't do business as normal due to damages caused.
Apart from fines and compensation, the true cost of food poisoning can be harder to measure as it can include reduced sales as a result of a damaged reputation, following an outbreak. Word of mouth can spread quickly about someone getting poisoned from a meal, leading to friends and family becoming wary of visiting or make a purchase again.
So, every business must consider putting plans in place so that a food poisoning incident never occurs in your business.
