From the cartoons given above, we can see that the doctor is checking the pesticide residues in fruits and vegetables. It wisely reflects the food safety issues which occur in recent years. Food safety related to people's health and it concerns about people's basic livelihood. Since the Sanlu Incident occurred in 20xx, the entire society was increasingly concerned about food safety issue. It was in this context that the food safety issue has been referred to an unprecedented height.
Problems leading to food safety are as follows: 1) using poor quality raw materials in the food manufacturing process; 2) adding toxic substances; 3) excessive use of food additives; 4) abusing of chemical additives and so on. There are many reasons that cause this problem. It is regulators, producers, and even consumers who share the responsibilities.
As Confucius instructed: better late than never. Prompt and strict measures should be taken to turn back this evil trend. The government should launch a massive moral campaign to educate all citizens and draw up tougher laws to crack down on those irresponsible corporations and prohibit them from entering the food industry again. I am firmly convinced that through our combined efforts we are bound to enjoy more risk-free foods in the days ahead.
