Promofoods concluded that the cans did not, after all,contain chemicals that posed a health risk. This conclusion is based on the fact that the chemists from Promofoods tested samples of the recalled cans and found that, of the eight chemicals most commonly blamed for causing symptoms of dizziness and nausea, five were not found in any of the tested cans.

Besides, the chemists only tested 8 chemicals which commonly cause the symptoms of dizziness and nausea. Thus, this action may lead to neglect other factors which may also lead to dizziness and nausea and even bring about damages to the health of customers. |
