Food hygiene assessment in catering establishments in Hay Hassani district-Casablanca

Contaminated food is responsible for a significant amount of illnesses. In Morocco, it has become a worrying concern. Numerous awareness campaigns are conducted to warn the population against the risks of such scourge in ways that will prevent foodborne illness. Lawful commissions are in charge of examining and ensuring food safety in production and catering establishments, in addition to the assessment of food poisoning risks. The aim of this study is to evaluate the hygienic quality of food handling, preparation, and storage in catering establishments within Hay Hassani prefecture in Casablanca. During the period 2006-2012 a total of 1765 food samples were taken and examined for microbiological quality tests. As analyzed, 562 per 1765 samples are declared unhealthy for consumption. We note that some products were highly contaminated as compared to other products (p <0.001), specifically vegetable dishes, and meat dishes. In Hay Hassani district food is generally prepared and sold under unhygienic conditions, adequate corrective measures have been announced to improve hygienic practices.

The effect of spinach supplementation on exercise-induced oxidative stress

AIM

Nutritional supplements have been very popular among athletes and individuals. Spinach is an important dietary vegetable rich in antioxidants which is commonly consumed. This study was conducted to assess the effects of chronic daily spinach supplementation on known markers of oxidative stress and muscle damage following half-marathon in well-trained healthy young men.

METHODS

Twenty well-trained men volunteered for this study. Participants were randomized in an open study placebo-controlled fashion into two groups: Spinach (S) (N.=10) and placebo (P) (N.=10). The participants took spinach supplementation or placebo daily for 14 days before running. Participants ran 21.1 km. The spinach supplementation was prepared at 1 g/kg body weight. Total antioxidant capacity (TAC) was determined as marker of plasma antioxidant capacity. Creatine kinase (CK) was measured as marker of muscle damage and malondialdehyde (MDA), protein carbonyl (PC) and uric acid were measured as markers of oxidative stress.

RESULTS

TAC significantly elevated after supplementation in S group (P<0.05). Acute exercise led to elevated levels of serum MDA, PC and CK (P<0.05). Spinach supplementation maintained PC, MDA, uric acid and CK at lower levels after exercise than the placebo (P<0.05).

CONCLUSION

These results suggest that chronic daily oral supplementation of spinach has alleviating effects on known markers of oxidative stress and muscle damage following a half-marathon in well trained healthy young men.

Effect of methylsulfonylmethane supplementation on exercise - Induced muscle damage and total antioxidant capacity

AIM

The aim of this study was to evaluate effect of 10-day methylsulfonylmethane (MSM) supplementation on exercise-induced muscle damage.

METHODS

Eighteen healthy, non-smoking, active young men were recruited to participate in this study. Participants were randomized in a double-blind placebo-controlled fashion into two groups: MSM (M) (N.=9) and placebo (P) (N.=9). Subjects consumed daily either placebo (200 mL water) or MSM supplement (50 mg/kg MSM in 200 mL water) for 10 days. Afterward, participants ran 14 km. Blood samples were taken before supplementation, before exercise, immediately, 30 min, 2, 24 and 48 h after exercise.

RESULTS

CK and bilirubin significantly increased in P group 24 h after exercise compared to M group (P=0.041 and P=0.002, respectively). TAC increased immediately post, 30 min, 2 and 24 h after exercise just in M group (P<0.05). TAC showed significant increase in M group 2 and 24 h after exercise compared to P group (P=0.014 and P=0.033, respectively).

CONCLUSION

It seems that 10-day supplementation with MSM has allowed to decrease muscle damage via effect on antioxidant capacity.
